Troubleshooting BMW Transmission Problems

A common problem many BMW owners face is the automatic transmission not shifting or erratic shifting. The first sign of BMW transmission problem is the Trans. Malfunction Drive Moderately message pops up on the screen.

Symptoms of BMW transmission problems vary. Your BMW may be running fine and then all of the sudden you get a transmission fault warning plus the car goes into Safe Mode/ Limp Mode. The transmission will no longer shift or go in reverse. 

Symptoms

  • Transmission stuck in gear
  • BMW Transmission slipping
  • Transmission malfunction message
  • Transmission shifts hard, not smoothly
  • Transmission malfunction drive moderate
  • Erratic shifting or bumping in one or more gears
  • The engine revs up and refuses to shift
  • Transmission Failsafe Prog. Warning
  • Lag between gears such as 1st to 2nd, 2nd to 3rd
  • Gear ratio fault codes
  • Erratic shifting when changing gear

What to do? 

Troubleshooting BMW transmission problems yourself is possible. Often times not only can you fix the problem yourself, but you can fix the problem by replacing only the defective part instead of replacing the transmission. Let's start with the most simple and basic troubleshooting steps.

Restart Engine

restarting your BMW will often get the car out of safe mode and fix transmission problemIf your BMW displays a transmission error message or is stuck in gear, the first thing you should do is find a safe location, turn off the engine and restart the car.

Wait at least one minutes and start the car. This may reset the transmission and the transmission malfunction message may turn off, which should allow you to get back on the road. 

If your BMW is back to shifting normally don't assume there is no problem. There is a high chance that you will experience the same transmission problem again.

While the problem may not seem major, if you ignore it, it can eventually get worse to the point that your BMW will no longer shift gears.

Reset automatic transmission 

If you have noticed that your BMW has erratic shifts or is not responding properly the problem may be fixed by following a few simple procedures that will allow you to reset BMW adaptive settings. This procedure is very simple, requires no tools and only needs a couple of minutes. 

BMW Transmission Reset Procedure

bmw automatic transmission reset
  1. Turn on the ignition. If your BMW has Start/Stop button, press the Start button but DO NOT press the brake pedal. 
  2. All the dash lights will turn on.
  3. Now, press the gas pedal all the way to the floor and keep it pressed. (Ensure the kick down switch is pressed )
  4. Keep the gas pedal pressed for 30 seconds. (During this procedure engine should be off, ignition still on.)
  5. Release the gas pedal.
  6. Start BMW and drive normally.

This will reset your transmission shifting to original factory settings. In other words, the BMW will erase the transmission shift points. For the next few driving cycles, your BMW will be monitoring your driving patterns; it is NOT recommended to drive aggressively.

Hopefully, this fixed your problem but if the symptoms will return again continue to the next step.

Read and Reset EGS Fault Codes

The next step is to read the fault codes. You will need a BMW specific OBD2 scanner that can retrieve fault codes from BMW modules. 

Typically you will be able to get a good scanner in the $100-$150 range. Generic OBD2 scanners won't help you with this task.

If you use a generic OBD2 scanner you will get generic fault codes such as P0720 or P0732 which don't provide enough details on what could be the cause of the problem.

What we used: Foxwell NT510 for BMW 

Alternative scanners: Top 10 Scanners for BMW

You should at a minimum read fault codes from the Transmission Module (EGS Unit), but a full system scan is recommended. Sometimes you may find there is DSC or ABS fault code. It is possible that a fault code in these systems can put your BMW automatic transmission into Fail Safe mode even if there is nothing wrong with the transmission. 

Erase all the codes. This will erase any stored codes and current codes. If your BMW transmission is working properly, great. If your BMW is still in Failsafe mode read the codes again. 

Check Transmission Fluid Level

check bmw transmission fluid levelIf transmission malfunction drive moderately error message pops up on your BMW, one thing that you should always check is the automatic transmission fluid level. If the trans level is low, even slightly, your BMW will go in limp mode to protect the transmission.

It is typical for a small amount of oil to leak especially in high mileage BMW. Add the missing transmission fluid, but do not overfill the transmission above the recommended level as this can cause shifting problems as well. 

Typical signs that the transmission fluid level is low, is that your BMW displays the Transmission Failsafe Prog." Warning if you try to accelerate by flooring the gas pedal or when accelerating as you are making a turn.

This happens because more transmission fluid is required during acceleration or the fluids gets pushed to one side of the trans oil pan when making a turn. Which means there is no transmission fluid for the oil pump which causes the transmission to go into FailSafe or Limp mode.

How to check BMW transmission oil

  1. Drive your BMW for 15 minutes to warm up the automatic transmission fluid. Make sure to allow the transmission to shift through all the gears. Transition fluid temperature should reach around 100 degrees F. during this driving cycle. 
  2. Park your BMW in a level surface or lift it up on a lift. 
  3. Let the car in park and at idle. 
  4. Remove the drain plug from the transmission oil pan. 
  5. A very small amount of transmission fluid should drain from the oil pan if the level is full. 
    If the level is low, there will be no oil coming out. 

Change Automatic Transmission Fluid

BMW may say their transmissions are sealed for life and require transmission fluid change. We don't believe that claim. Our recommendation is to change the transmission fluid every 60k miles.

What you will need: 

Only used the recommended transmission fluid for your BMW.

  1. Filter and Gasket Kit
  2. ZF Lifeguard fluid
    • 4.5 qt if only draining oil pan
    • 9.5 qt for full system flush
  3. Fluid Transfer Pump
  4. Torx Socket
  5. Drain Pan

If you experiencing random shifting issues, consider changing the automatic transmission fluid and filter. There is a lot of discussions and often disagreement whether you should or should not change the automatic fluid in a BMW especially on a transmission that is sealed for life.

In our experience, fresh fluid and transmission fluid will only help to extend the life of the transmission. The only times that things get worse, is when there is an already existing issue with the transmission. 

A BMW automatic transmission holds about 9.5 qt of ATF fluid. That is full system capacity, which includes all the oil in the transmission, oil pan, and torque converter. If you are not going to flush the whole system but only drain the oil pan you need about 4.5 qt of oil. 

Common BMW Transmission Problems

Transmission Mechatronic Sleeve

bmw  mechatronic sleeve locationCheck for an oil leak at the electrical connector. The mechatronic sleeve is located on the passenger's side of the transmission near the end of the automatic transmission. This is where the wire harness from the Transmission Control Unit (TCU) connects the transmission.

This is usually near the back of the transmission. If you unplug the wire harness, you may notice an oil leak at this plug. If there is any oil, not only it means you are losing oil, but the communication between the ECU and the mechatronic valve body is interrupted.

To replace or check for leaks you will need to get your BMW up on ramps. Remove the splash shield from under the transmission and unplug the wire harness.

What you will need: BMW Mechatronic Sleeve ( Part #: 0501 216 272 01)

DIY Instruction: How to replace BMW Mechatronic Sleeve, Alternative Guide

Mechatronic Bridge Seal adapter 

Mechatronic adapter Another reason why a BMW may display “Transmission Fault” warning message on the iDrive screen is due to a cracked adapter (trans seal grommet)  for the mechatronic valve body.

Under normal condition the grommet allows the fluid to flow from the transmission to the mechatronic valve body without any fluid loss.

This allows transmission fluid to make it to the mechatronic without any pressure loss which in turn allows normal gear shifting.

The grommet or the plastic adapter can crack over time, which allows the fluid to leak at this port. When this happens the fluid pressure at the mechatronic valve body is reduced.

Because the fluid pressure is reduced the solenoids in the valve body cannot open and close properly which triggers the transmission fault or erratic shifting.  

This part is easy to replace and comes in plastic or aluminum.

The OEM part sold at BMW is usually plastic, but upgraded aluminum adapters can be purchased online and last longer than the plastic version. 

This problem is common on these BMW transmissions: 6HP26, 6HP28, and 6HP32. An improved Aluminum Part Number SFC-MA-001 is available.

Another indicator that this part is broken is that you will get the “transmission Fault” popup typically when you move the shifter from drive to reverse. You usually back up a few feet and put the transmission back in drive.  

What you will need:

BMW Mechatronic adapter  (Part #: 0501 215 783 01)

List of cars most affected by this problem: 

  • 2001–2008 BMW E65/E66 7 Series
  • 2004–2006 BMW E53 X5 V8
  • 2003–2010 BMW E60 5 Series
  • 2005–2011 BMW E90 3 Series
  • 2003–2010 BMW E63/E64 6 Series
  • 2007–2013 BMW E70 X5 Except 4.0d
  • 2008–2012 BMW F01/02 7 Series (except 760i/Li and Hybrid 7)

Mechatronic Problem

bmw mechatrnoicIf you read the codes, you may get fault codes related to the valve body also known as the BMW mechatronic. BMW ZF mechatronic are notorious for problems with 2 to 1 st gear downshift or shift flare during the upshift.
 
These harsh upshifts and downshifts are often due to a TTC clutch failure, overheating, damaged solenoid, worn selenoid springs and other problems with the mechatronic unit.
 

If you checked everything above but are still having problems with your BMW transmission the cause most likely is the mechatronic unit. If you are looking to save money, you can consider replacing only the solenoids in the mechatronics unit/valve body.

If you decide to replace the solenoids yourself, remember to change the foam strip that goes between the solenoid terminals and connectors. 

You can buy a cheap BMW transmission solenoids online. Check the price of BMW Mechatronic Solenoids here and follow this guide on how to replace them.

If you want a unit that has already been remanufactured and tested, you can buy a remanufactured BMW Mechatronic unit online. If you have some basic DIY skills, you can replace the mechatronic unit on a BMW.

Keep in mind that the unit often needs to be codded to match your BMW VIN. Before you purchase a replacement mechatronic unit, check with the seller or BMW dealer if programming or coding is required. 

It is possible to replace BMW mechatronic yourself. 

If you would rather let a mechanic do the work, this repair can cost anywhere from $1500 to $3500. If you decide to have the dealer replace the mechatronic on your BMW, it will usually cost anywhere between $2100 and $3500.

It is recommended to reset the transmission module after the Mechatronic replacement. Drive the vehicle around for about 15-20 minutes making sure transmission cycles through all the gears several times to recalibrate the shift points. 

EGS Transmission Control Module Software Update / Reflash

BMW often comes up with software updates for the automatic transmission. These updates change the shift points which improves the shifting.

In some cases, it has been reported to fix erratic shifting problems or SAFE MODE issues. You will need to call your BMW dealer and ask them if there is a software update for the transmission for your particular car. You will need to provide the dealer with the VIN number of your BMW.

Transmission Stuck in FailSafe Mode

We have seen cases where the BMW transmission will get stuck in second or third gear and will not come out of failsafe mode even if you restart the car. In one case this problem was caused by a dead battery that stored hard codes.

Even though the BMW battery was replaced the car remained in Failsafe mode. Typically a BMW will go into failsafe mode if the voltage is under 9 volt.

If a hard code is stored in the EGS module you will need a BMW Specific Scanner to clear the fault codes from the EGS module. Low battery voltage can also cause the transmission to not go into Drive or Reverse.

Temporary Fix, 2 Tip 1 

Often the transmission issue may be with due to a problem with the first gear only. To verify that the problem is with the first gear, set your BMW transmission in Winter mode, which forces the transmission to start in second gear.

If your BMW shifts normally when in winter mode that means there is an issue with the first gear. Keep the transmission in winter mode, until you get your BMW transmission repaired. 

BMW Stuck In Park

If your BMW is stuck in park and the shifter won’t come out the problem could also be the brake light switch or park solenoid. 

BMW Transmission Shudders

BMW that are equipped with twin turbo may experience shuddering symptoms, especially during a long trip. To verify that this is the issue, it is recommended that you stop your car and let it cool down.

If transmission shuddering symptoms go away when the engine cools down then it is possible that the problem is caused by the twin turbos.  Check engine light may also come on. Symptoms often happened between  50-70 mph. 

Another reason why you may experience transmission shudder is due to issues with the torque converter. This is often due to the fact that the torque converter lock-up is wearing out and not locking the torque converters. 

BMW transmission shudder may also be caused due to spark plug or fuel injector problems. If the check engine light is on, make sure to scan the codes from the ECU so that you can get a better idea of why the transmission shuddering is happening.

Hi we had are x5 gearbox reconditioned 2 years of and then last week it came up on the dash transmission fail self mode and it won't go past 3rd gear what can it be

Cindy , 2019-01-31

Tony - did you solve your problem, I have something similar now with my 2006 5 series

Hi

Hoping you can provide some help.

Further to your post, I’ve had an issue with limp home for 2000 E46 323i.

What occurs is that if the Air Con is on and I come to a stop (eg at a traffic light or stop sign, etc) the gear symbol comes up in the dash and transmission goes into limp home mode.

If I have the Air Con off there is no problem, or, if I turn the Air Con off before stopping again no issue.

The issue seemed to have commenced after a mechanic replaced the radiator fill bottle and hoses due to a crack in the bottle, I’m not sure he replaced the transmission thermostat at the base of the bottle or not. I had initially thought this may be the problem as it is difficult to replace the bottle without cracking that thermostat, I understand if that thermostat is damaged you get the limp home happening as well. However, as above I find limp home only occurs if Air Con on at time of stopping car.

Thanks

Mark

Hi Mark,

There is a good chance that you have a problem with the cooling system. When you turn on the A/C the radiator cooling kicks in automatically. If the car detects a serious cooling system issue, it will put your car into limp mode so that you know plus the transmission doesn't get damaged.

Do a full system scan and see what codes come up.

Engine fault ,reduce power is coming on the screen .
Have a BMW 525 D 2010 model ...The drive is not as peppy as it used to be what could be the issue .

Terry Mulligan, 2019-01-06

I have a 2008 BMW X5 with 82000 miles, the trans is going into limp mode malfunction. WE stop the car and shut off wait a couple minutes and it drives ok. This happens now and then,i have a Foxwell scanner 510 and it says clutch c fault. I reset and cleared the code and it will drive normal. Could this be a electrical problem, maybe a bad ground? Any thoughts would be great. Thanks

Debbi Snyder, 2019-09-29

Did you ever get to the heart of the problem? My 2005 BMW X5 is doing the same thing and I have not been able to get any answers. Thanks so much!

Mike.99.528i, 2019-01-11

Agreed best Tech post ever, A+ Work. One question, are these trouble shooting steps genetic year to year (will steps mentioned above work on a 01' 530i?)

JT750Li,325i, 2019-03-06

Conceptually should be very similar, just confirm parts and keep looking for the gold nugget posts..
also when you find a good search phrase.. i.e. BMW mechatronic valve sleeve replacement (or whatever)

.. then use that same phrase in different Search Engines as well as adding " .pdf " to the end - etc,. etc.

I have a 2006 BMW 320i M-sport, the Transmissions brings error code CC-ID 254 – Transmission Malfunction Emergency Program. I usually stop the car, turn it off completely then turn it back on after some time, the second thing is the gear slightly struggles to shift from 3 to 4 producing a squicky sound. I tried to reset the transmission but error keeps coming back.

So i just bought a 2005 645ci bmw, the second night of owning it i had tried to see what it can do in sport mode. I was doing around 140mph and the trans went into limp mode. When i check to see if my battery was good it reads 14 volts running with no accesories. With all my acceseries running such as radio, fan, headlights and heated seats on it only read around 12 volts. Could my alternator cause this problem?

Thomas Clark, 2019-03-27

My 2013 328i had an error code B7F668 and the transmission made a big bang. I turned it off and it cleared and has been fine for 5,000km then I had a transmission fault again today but no error code recorded on the DTC list.

I have a proble with my BMW 525i 2008 model just change the gearbox and and filter but the it still does not change gears and still has the transmission fault mesaage on the screen

Hi i am new to the bmw world and recently purchased an 06 automatic 330xi. It runs and drives great under normal conditions. I have noticed that If I really step on it causing it to hold in gear longer it will hesitate on shifts above 4k or so rpm and jerk a little. It seems to have an issue a higher rpm shifting to the next gear. I have not checked the fluid level yet nor do I know when the lats trans service was done. The car has just over 150k on it and was a well maintained 1 owner car.. I did not notice this on the test drive since you really have to get on it to make this happen. It typically does not register as any sort of fault but did yesterday for the first time. I tried getting it up to around 5k in 4th gear (using the manual shift feature) and it seemed to not want to go into 5th, even though it said it had on the dash. I tried shifting again and it really didn't like that and immediately gave me an error message. I am assuming it tried to go into 6th gear from 4th and this is why I received the message. I reset it and the message went away. I plan on doing a filter and fluid replacement in the near future and was wondering if I could get any advice on what may cause this issue. Other than this the car up shifts and down shifts smoothly without issue under normal driving conditions. Thanks

2007 530xi trans just gears down on the highway n resets after I shut it off but then happens again ? 128,000 on it

Martin N, 2019-04-16

1998 328i hard shift (Bang) got better after fluid and filter Change. It went away completely when I replaced the two forward shift solenoids and did the band adjustment (4L30E GM transmission). Now there is a pause when I shift from reverse to Drive first thing in the morning then an occasional odd shift in D, but not in 3rd. Next I’ll try resetting the Transmission and check fluid levels again just for good measure. I’ll post an update if the reset helps.

05 BMW 325ix AWD 5 speed automatic transmission with Steptronic, 156,000 miles on car.
VIN#- WBAEU33495PR15614,
DoP- 08/04

Electronic Transmission Control Module
indicator warning lamp
1.) came on under normal driving
2.) holding gears longer before shifts
3.) very hard up & down shifts
4.) speratic as to what rpm/Rd. speed downshifts will accure
5.) higher rpm long it holds the gear
6.) have all gears as normal (not it limp mode)
7.) if foot on brake pedal accelerator pedal is inactive

Things I've tried to fix this:
1.) put it in P, shut car off, set E-brake, removed key waited couple mins and restart. no difference!
2.)turn key on to pos#2 but didn't start engine, pushed & held accelerator pedal to floor for 30sec. restart car. no difference!
3.) scanned engine codes- 1st time got code for MAS voltage drop. miss fire bank 2. fixed by removing and cleaning MAS and replacing wire clip on electrical plug. rescanned no codes!
4.) scanned trans codes. no codes!
( note: when I clear codes from engine or trans turns light off on dash untill restart and runs for 30-45 sec. can here trans/engine change tones when running and light turns back on)
(note code scanning done with cheap Walmart and a cheap Bosch pocket scanners)
5.) just put car on ramps. So to look for leaks, loose wires and check trans fluid level. will do these in the morning.
Great job on Wright up just as others have said!
Your thoughts would be highly appreciated!!!

Have BMW 325ix up in air. Very, very little seepage around drain/fill plug like 1/2" diaimator around drain/fill plug. Front trans axel/differential leakes. Have degreased entire underside of car dried off ran car for approx 1.5hrs to help aid in drying.
Need to level car in air to check fluid and top off still. Then top off front and rear differentials, and transfrecase. I guess at that point I will drive it a bit to see where frond diff leak is and if there is any other leeks. Unless you have a next step better suggestion?? Looked all over net can't find anything about any BMW with malfunction light on but not in limp mode. It does kill any acceleration via gas pedal if you step on brake. Noticed this putting it up on ramps. Another thing I noticed is that cruise control will not turn on because of this. It was working just mins before light came on dash. My aribag center clock spring is bad I'm pretty sure. Does that have any relation to my problems??
Any reply , help or pointing me in right direction would be much, much appreciated!!
Thanks Robert

Hi Guys,

I have a 2008 330i convertible which is showing a transmission faulty warning light. The garage recommended changing the fluid and filters, which I didn’t. After leaving the garage (20 minutes of driving) the warning light came back on.

Any advise, before I spend even more money.

Many thanks

Hello, I was hoping that someone out there could help me I was just given my first BMW it's a 2003 530i... " love it " but for some reason it went into the safe/limp mode. It was fine when I parked it the next morning my battery was dead I got a jump and boom it was in this mode..i did just read it is possible my battery stored some bad codes. My battery light does come on every time I hit the Has But then goes a way when i let up....Has this happened to anyone else? Maybe you could point me in the right direction to find a special BMW code reader/reseter.
I hate to put my business out there but I don't have any money since my ex emptied my account 2 weeks ago.. Won't be cheapest would be great...
Thank you

@Travis barrette. I have the same vehicle. Had issues with alternator, charging etc. I put in a new battery. Also monitored voltage each day. I found it only started charging after a few miles. I got a replacement control module for the alternator. Also stopped all the oil leaks that were dripping onto the alternator. Now okay. My theory : Oil was leaking into the alternator. Overnight this would accumulate. So in the morning the oil, being an insulator, was stopping the alternator from charging properly until I had driven a few miles. By this time, centrifugal force had thrown off the oil and the alternator resumed charging.

My 2002 BMW 325I it has run great no problems then I pulled into a parking spot and it was slipping got out and transmission fluid was all over rear of car and car would go into all gears but not go and continue to leak. Any ideas

Rolando, 2019-08-24

I have a 2011 740I and the gear shift selector will not go into park. It goes into all the other gears so I'm able to drive the vehicle. When I park I have to leave the vehicle in neutral and apply the parking break. Dealership said the mechatronics is failing so it needs replacing. Of course they want a ton of money to do this. Do you think I can just replace the solenoids and get the shifter to go back into park or could it be a fluid level problem? Thanks

Hi!
I was wondering if I have a 2005 530i bmw and I wanted to put a 2004 330i transmission in it. Is that possible at all!

Thanks

I've encountered the following problem.
Got an F25 N47 automatic transmission Sdrive.
After replacing the engine control, the automatic transmission shifts to safe operation mode and reads the following error message (420321) does not shift in or out of 2 gears. Cables are OK.The measured voltage was 11.3 in the positive cables.I've already done the adjustment and calibration and nothing has improved.

2006 530i
I've done the solenoid swap, bridge seal, mechatronic sleeve, installed new fluid but trans won't move. Plugged in my Foxwell scanner, with shifter in Park, Nuetral and drive is shows to actually be in first gear. Did I get the shift arm back together wrong? It looked just like the picture in your article, could I have had it slide the wrong direction when installed?? If not could I clear it with my scanner?
