This guide will show common Honda transmission problems. Typical symptoms and how to check the transmission fluid and read fault codes yourself. 

Early 2000s V6 Honda models such as the Odyssey and Accord had higher than normal automatic transmission failures.

Newer models are not trouble-free either. 2015-2018 Honda and Acura vehicles with ZF 9HP 9-speed automatic transmission were recalled due to problems with gasket leaks that allowed engine coolant and transmission fluid to mix. If coolant is mixed with transmission fluid, it will damage the transmission bands, requiring complete rebuilding.

Symptoms of Honda transmission failure include:  

  • Transmission slips
  • Lack of response
  • Car jerks when accelerating.
  • Burning smell
  • Car refuses to move when in gear.
  • Transmission slips when changing gears.
  • Whining, clunking, or humming noise
  • Transmission is noisy in neutral.
  • Transmission pops in and out of gear.
  • Transmission slips or won't engage.
  • No 1st, 2nd, 3rd, or 4th Gear
  • The engine revs up before the car starts moving.
  • No reverse
  • Thumps or clunks noises when changing gears
  • Check engine light always on
    • Common codes: P0700, P0730, P0740, P0780, P0705
  • D, D4, or D3 light flashing
  • The vehicle goes in limp mode.
    • Speed limited to 30 mph.

In most cases, one to two symptoms will be present depending on your Honda transmission problem.

Symptoms range from delayed engagement, engine revving up, check engine light stays on, "D" light flashing.

These symptoms are eventually followed by a transmission that slips, goes in and out of gear, and if these symptoms are ignored, they will eventually lead to complete transmission failure.

Honda transmissions that malfunction should be diagnosed as soon as possible in order to prevent further damage.  

How to check transmission fluid on a Honda? 

Check the transmission fluid level as soon as possible. If the level is low, add the recommended amount of Honda transmission fluid.

Signs that the Honda transmission may be low on transmission fluid include delayed engagement, transmission slipping, and rough shifts between gears.

  1. Drive the Honda for fifteen minutes to warm up the transmission fluid, then park it on level ground.parked honda
  2. Turn off the engine. turn off engine honda civic accord
  3. Open the hood by pulling the hood release under the dashboard. open hood
  4. Locate the transmission fluid dipstick. transmission dipstick
  5. Remove the dipstick and wipe it clean. Note the MIN and MAX marks. Reinsert the dipstick making sure it is fully inserted. check honda transmission fluid
  6. Remove the dipstick to determine the fluid level. The level must be in the hatched area. transmission fluid level

This is a straightforward procedure and only takes less than five minutes.

If your transmission fluid level is low, add the recommended Honda transmission fluid specified in your owner's manual.

Low transmission fluid level can cause the engine to rev up when the automatic transmission changes gears. It can also cause the transmission to bang into gear or whining noise coming from the transmission.

How to diagnose Honda transmission problems? 

Transmission problems will, in most cases, generate a fault code. Transmission-specific fault codes get stored in the transmission control unit and will not always set the "check engine light."

Generic OBD2 scanners cannot read transmission fault codes. In addition to diagnosing the check engine light, your scanner needs to diagnose the transmission module as well.

What you need

A scanner that can diagnose Honda transmission problems. Here are a few popular choices.

These scanners can read and clear fault codes from the transmission module.


  1. Locate the OBD-II port under the dashboard.
  2. Turn on the ignition.
  3. Allow your scanner to turn on.
  4. Select your Honda model, then go to the Control Unit.
  5. Select the Automatic Transmission menu.
  6. Scroll down to Read Codes and press enter.

If you have a scanner designed for Honda, it is good to perform a full system scan that will read codes in all modules.

Sometimes a problem with the mass airflow sensor, Powertrain Control Module PCM, or VSS can cause your transmission not to shift, shift erratically, or go into limp mode.

Honda TCC Lockup Solenoid Resistance Test


On Honda equipped with the four-cylinder engine, the problem could be due to the TCC lock-up solenoid. This may be the problem if you are getting fault code P1735.

Using a digital multimeter, you can perform a TCC lock-up solenoid test by meaning the resistance. The TCC solid does not need to be removed from the vehicle; it just needs to be disconnected.

Follow this guide on how to perform a TCC lock-up solenoid test.

TCM Software Update

Honda Transmission Control Module (TCM) may malfunction.

Honda transmission problems can also be caused due to TCM software keeping the torque converter engaged even when it is stopped. This condition puts unnecessary stress on the transmission and can shorten the life of the transmission.

Honda has come up with a transmission software update that can prevent the lockup clutch from staying engaged.

Call your Honda dealer to give them your VIN and ask if there is a transmission software update. The dealer may let you know over the phone or require you to take the car to verify.

Check Battery Voltage

low battery voltage causing transmission problems

Hondas that are equipped with the latest 10-speed automatic transmission are very sensitive to voltage fluctuations.

Low voltage can cause the TCM to reboot, which places the transmission in Park or Neutral.

Honda issued a recall for this problem where a software update changes the behavior on TCU reboot. NHTSA campaign number: 19V299. Honda recalls are Z4J and Y4K.

If your Honda is affected by the recall, take it to the dealer to get it serviced. If not, ensure your Honda battery is fully charged. Read fault codes from the transmission module to find out if the codes are voltage-related.

Change transmission fluid and filter

Only use the recommend Honda transmission fluid. Using aftermarket transmission fluid can lead to erratic shifting or premature gearbox failure.

On high mileage vehicles, metal particles in the transmission fluid can cause solenoid failure. Metal from the torque converter or clutches is carried in the transmission fluid, which then gets into the solenoids.

To fix this problem, you will need to do a complete transmission fluid flush, and in some cases, you may even need to replace the valve body.

  1. Drain out the old transmission fluid.
  2. Clean the drain plug magnet
  3. Add three quarts of genuine Honda transmission fluid.
  4. Check transmission fluid level with engine off.

Keep in mind that the transmission fluid pan only holds about 1/3 of the fluid. The rest of the transmission fluid is in the torque converter, lines, and cooler. To get a 100% transmission fluid change, you will need to perform a flush. If you are changing the transmission fluid every 30,000, it is not necessary to perform a flush.

To extend the life of your Honda transmission, it is strongly recommended to change the transmission fluid and filter at the recommended interval. Honda recommends changing transmission fluid between 60,000 and 90,000 miles depending on the transmission model. In some models, Honda transmission filters are considered lifetime filters and can not be easily serviced.

What transmission fluid to use on a Honda?

Using the correct transmission fluid in your Honda is very critical. The transmission fluid that you must use depends on the type of transmission installed in your car. Transmission and fluid types are listed in your owner's manual.

Here is a list of most commonly used Honda transmission fluids:

The correct transmission fluid is indicated in your owner's manual.

How to fix a broken Honda transmission? 

Call any Honda dealer and provide them with the VIN. Ask if any recalls may affect your vehicle. If not, ask if they will offer a "Goodwill repair."

If the dealer does not cover your Honda, here are some of your options:

Used Honda Transmission

  • This is the cheapest route but the least reliable. A used transmission can be purchased from a local salvage yard.
  • A used Honda transmission will cost anywhere from $350 to $600. A local mechanic can install the transmission for $500-$700.
  • The main disadvantage of installing a used transmission is that there is no guarantee. Even if the used transmission comes with a 30 or 90-day warranty, it may fail at any time after that.

Rebuilding a Honda Transmission

  • Since certain Honda transmissions tend to fail quite frequently, there are transmission shops that specialize in rebuilding Honda transmissions.
  • While they cost more than a used transmission, a good rebuild transmission should last several years.
  • Rebuild transmissions also have a better warranty, typically a 30,000 or 50,000-mile warranty, which is significantly higher than what you will get from a used transmission.
  • A rebuild transmission will be shipped to you or your mechanic. The mechanic will then install it for you for an additional fee. You are looking to spend between $1600 and $2500 in total.
  • Note that some Honda transmission rebuilders require that the old transmission should be returned.
  • You will be charged a core fee, which will be refunded when you return the old transmission.

Remanufactured Honda Transmission

  • The most expensive solution is to buy a rebuild Honda transmission. You can have your local Honda dealer install a remanufactured Honda transmission.
  • These transmissions are rebuilt by Honda technicians and with OEM parts.
  • This route will be more expensive, but it is less headache.
  • Remanufactured Honda transmission comes warranty that is honored by Honda dealerships.
  • Having Honda replace a failed transmission typically costs between $3000 and $4500.

Check Recalls

Honda has recalled millions of Honda Accords, Odysseys, and Pilots due to transmission problems. You can check if there is an open recall for your vehicle by going to the NHTSA Website and entering your VIN.

What are the most common Honda transmission codes? 

While there are hundreds of possible fault codes, here is a list of the most common Honda transmission fault codes.

  • P0766 “ Failed Shift Solenoid D “ This DTC can be stored when there is a problem with a shift solenoid or the valve body.
  • P2703 “ Failed Friction Element D “ This trouble code can be triggered by a failed friction element like a clutch disc.
  • P0720 “ Failed Input Speed Sensor or Output Speed Sensor “ This trouble code is caused by a bad speed sensor on the transmission.
  • P0730 “ Incorrect Gear Ratio “Several problems could cause this issue, including a fault in the transmission control module, dirty transmission fluid, or a bad transmission solenoid.
  • P0657 “ Voltage Problem in the A Circuit This transmission problem is often caused by a short or bad ground on the PCM or PCM wiring harness.
  • P0700 “ Malfunction in the transmission control system “ This DTC is often triggered when there is a problem with the TCM, a wiring harness, a solenoid, or the valve body.
  • P0715  Input/Turbine Speed Sensor Malfunction “ This code typically gets stored when the input sensor cannot read the engine RPM, which can prevent the transmission from appropriately shifting gears.
  • P0717 Input/Turbine Speed Sensor No Signal “ This trouble code is generated when the PCM does not get a signal from the input speed sensor, which will prevent the computer from being able to determine when the transmission needs to shift.
  • P0791 “ Intermediate Shaft Speed Sensor A Circuit This error can occur when there is a problem with the intermediate shaft speed sensor, most likely due to a bad sensor, wiring problem, or a failed shift solenoid.
  • P0793 “ Intermediate Shaft Speed Sensor Circuit No Signal “ The computer will generate this DTC when it cannot communicate with the intermediate shaft speed sensor.

Why do Honda if my transmissions fail?

Not all Honda transmission fails. In those that do, a common problem with Honda transmission is inadequate cooling of transmission fluid.

Transmission fluid that's not cooled enough causes gears to overheat, more especially the second gear. Extreme heat causes the transmission fluid to break down, which causes internal transmission failure.

For models with this issue, Honda issued a recall where a transmission fluid cooler was installed to address the issue.

Which Hondas should I avoid?

  • Honda with the V6 engine and automatic transmissions from 1999 to 2003. The most problematic Honda transmission is the H5 transmission. The early model years had high failure rates. In the latter years, Honda improved the parts used, and the failure rate has significantly decreased.
