Troubleshooting Honda Transmission Problems

Have troubles with your Honda transmission? Learn the typical symptoms, 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. Newer models have their own issues. Honda has released software updates for harsh or jerky shifting on its 9-speed automatic in the Pilot, Odyssey and Passport, a torque converter warranty extension for some 2017 to 2019 six speed models, and a recall for 2014 to 2015 Civic CVTs (details below). On the 2016 Pilot, Honda bulletins also addressed 9-speed transmission warmers that could let coolant and transmission fluid mix, with an extended warranty on the warmer (bulletin list). Coolant in transmission fluid destroys clutches and usually means a rebuild.

Which Transmission Does Your Honda Have?

Transmission	Typical models	Fluid
4 and 5 speed automatic (4AT, 5AT)	Older Accord, Civic, CR-V, Odyssey, Pilot	Honda ATF DW-1
6 speed automatic (6AT)	V6 Accord, Odyssey, Pilot, Ridgeline (mid 2010s)	Honda ATF DW-1
CVT	Most 2014 and later Civic, CR-V, Accord 4 cylinder, HR-V, Fit	Honda HCF-2 (check manual)
9 speed automatic (9AT)	2016 and later Pilot, 2018 to 2019 Odyssey LX to EX-L, Passport, some Ridgeline	Per owner manual
10 speed automatic (10AT)	2018 and later Odyssey upper trims, Accord 2.0T, later Pilot and Passport	Honda ATF Type 2.0

Your owner manual names the exact fluid. Honda says not to mix HCF-2 with other fluids (Honda CVT manual page) and not to mix ATF Type 2.0 with others in the 10-speed (Honda 10AT manual page); damage from the wrong fluid is not covered by warranty.

What Honda’s Own Bulletins Say

Torque converter judder on six speed V6 models

Honda bulletins for the 2013 to 2017 Accord V6, 2017 Ridgeline and 2014 to 2017 Odyssey describe judder from the torque converter clutch, and state that “the torque converter is not at fault.” The fluid breaks down early after repeated high heat. The fix is a software update followed by three DW-1 fluid flushes, covered for 8 years or 80,000 miles (Honda SB 17-018, SB 17-044). The 2012 to 2014 CR-V (a five speed automatic, not a CVT) has a similar judder fix with software and fluid (Honda SB 15-086).

Real torque converter failures (2017 to 2019)

On certain 2017 Accord and Odyssey, 2017 to 2018 Pilot and 2017 to 2019 Ridgeline, a cracked lock-up piston can make the D indicator flash with a transmission overheat message and code P0741. Honda replaces the torque converter and has extended coverage to 10 years or 150,000 miles (Honda bulletin 23-076).

CVT surge, judder and flashing D

On the 2013 to 2014 Accord four cylinder CVT, Honda fixes surging or judder from a stop with a new lower valve body and software (Honda SB 13-053). On 2016 to 2018 Civic 1.5T, 2017 to 2018 CR-V and some 2018 to 2019 Accord CVTs, a flashing D with code P2817 gets a software update (Honda SB 19-047). These carry normal warranty only.

9 speed harsh or slow shifts

For the 2016 Pilot, Honda updates the PCM and TCM together for surging, slow downshifts and hesitation, then allows up to 30 miles to adapt (Honda SB 16-008). For 2018 to 2019 Odyssey, 2019 Passport and Pilot Touring and Elite, harsh upshifts get a TCM update that takes about 500 miles to fully adapt (Honda SB 19-124). Ask your dealer whether your VIN has open software updates before paying for repairs.

Symptoms

Symptoms of Honda transmission failure include:

• Transmission slips
• Lack of response
• The car jerks when accelerating.
• Burning smell
• The car refuses to move when in gear.
• The transmission slips when changing gears.
• Whining, clunking, or humming noise
• Transmission is noisy in neutral.
• The 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 into limp mode.
  • Speed is limited to 30 mph.

Depending on your Honda transmission problem, one to two symptoms will usually be present. Symptoms range from delayed engagement to engine revving up, check engine light staying on, and “D” light flashing.

These symptoms are eventually followed by a transmission that slips and goes in and out of gear, and if these symptoms are ignored, they will eventually lead to complete transmission failure. To prevent further damage, Honda malfunctioning transmissions should be diagnosed immediately.

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. The Honda transmission may be low on transmission fluid, including 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.
2. Turn off the engine.
3. Open the hood by pulling the hood release under the dashboard.
4. Locate the transmission fluid dipstick.
5. Remove the dipstick and wipe it clean. Note the MIN and MAX marks. Reinsert the dipstick, making sure it is fully inserted.
6. Remove the dipstick to determine the fluid level. The level must be in the hatched area. 

This straightforward procedure 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 usually generate a fault code. Transmission-specific fault codes are stored in the transmission control unit and do not always set the “check engine light.”

A basic OBD2 reader may show a generic P07xx code, but it often misses Honda specific transmission codes and live data. Use a scanner that reads the transmission or powertrain module directly.

What you need

A scanner that can diagnose Honda transmission problems. The YOUCANIC full system scanner can read and clear all codes on any vehicle’s control module.

• YOUCANIC Full System Scanner

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

Instructions

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 recommended that you 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

The problem for Hondas equipped with four-cylinder engines could be the TCC lock-up solenoid. If you are getting fault code P1735, this may be the problem.

By meaning the resistance, you can perform a TCC lock-up solenoid test using a digital multimeter. 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

The Honda Transmission Control Module (TCM) may malfunction.

Honda transmission problems can also be caused by TCM software keeping the torque converter engaged even when stopped. This condition puts unnecessary stress on the transmission and can shorten its life.

Honda has developed 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 inform you over the phone or require you to take the car to verify.

Check Battery Voltage

Hondas 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, in which a software update changed the behavior of the TCU reboot. The NHTSA campaign number is 19V299.

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. Then, read the transmission module’s fault codes to determine if they are voltage-related.

Change transmission fluid and filter

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

Metal particles in the transmission fluid can cause solenoid failure on high-mileage vehicles. Metal from the torque converter or clutches is carried in the transmission fluid, which then enters the solenoids.

To fix this problem, you must complete a transmission fluid flush; sometimes, you may even need to replace the valve body.

1. Drain out the old transmission fluid.
2. Clean the drain plug magnet.
3. Refill with the same amount that drained out, using the genuine Honda fluid your owner manual specifies, then check the level.
4. Check the transmission fluid level with the engine off.

Remember 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. You must perform a flush to get a 100% transmission fluid change. If you change the transmission fluid every 30,000, performing a flush is unnecessary.

To extend the life of your Honda transmission, it is strongly recommended that you change the transmission fluid and filter at the recommended interval. Most current Hondas tell you when to change the fluid through the Maintenance Minder: sub item 3 means “Replace transmission fluid,” and Honda suggests about every 25,000 miles if you often drive at low speed in mountainous areas (Honda owner manual). Do not wait for the message if you tow or see judder; Honda notes fluid can break down before the service message appears (Honda SB 17-044).

What transmission fluid to use on a Honda?

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

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

• Honda ATF DW1
  • Automatic transmission Hondas
  • Replaced Z1
  • Most common
• Honda MTF
  • All manual transmission Hondas
• Honda CVT Fluid
  • Continuously Variable Transmission
  • Civic Hybrid,
  • CRZ, Civic GX HX,
  • Insight
• Honda HCF2 Fluid
  • Second-generation CVT transmissions
• Honda ATF-TYPE 3.1
  • 2016 Pilot (9-speed)
• Honda ATF-TYPE 2.0
  • 2018 Odyssey (LX, EX, EX-L)

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 to $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 anytime.

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 rebuilt 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 rebuilt 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 the old transmission to 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 rebuilt 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

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

NHTSA recall	Vehicles	Problem	Remedy
04V176	About 1.1 million V6 Accord, Odyssey, Pilot and Acura models (early 2000s)	Second gear overheating can break gear teeth and lock the transmission	Cooler line modification; transmission replaced if damaged
15V574	2014 to 2015 Civic CVT, 2015 Fit	CVT drive pulley shaft can break, causing loss of drive or wheel lockup	CVT software update
19V299	2018 to 2019 Odyssey (10-speed)	Low voltage can reboot the TCU and shift to Park while driving	Battery terminal fix and TCU software

Sources: 04V176, 15V574, 19V299. In 2002 Honda also extended transmission coverage to 7 years or 100,000 miles on about 1.2 million 2000 to 2001 Accord, Odyssey and Prelude and Acura TL and CL models (just-auto report); that coverage has long expired.

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 “A bad speed sensor on the transmission causes this trouble code.
• 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 A short or bad ground on the PCM or PCM wiring harness often causes this transmission problem.
• 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, preventing 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 Transmissions Fail?

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

Transmission fluid that’s not cooled enough causes gears to overheat, especially the second gear. Extreme heat causes the transmission fluid to break down, which causes internal transmission failure. Honda’s 2004 recall (04V176) addressed this on about 1.1 million V6 Accord, Odyssey and Pilot models and Acura MDX, TL and CL: the dealer modified the transmission fluid cooler return line to send more lubrication to second gear, and replaced the transmission if the gear already showed heat damage (NHTSA 04V176).

Which Hondas should I avoid?

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