Metal from the torque converter or clutches is carried in the transmission fluid, which then gets into the solenoids. Metal particles in the transmission fluid can cause solenoid failure on high-mileage vehicles. Using aftermarket transmission fluid can lead to erratic shifting or premature gearbox failure. Only use the recommended Honda transmission fluid. Read the transmission module’s fault codes to determine if the codes are voltage-related. If not, ensure your Honda battery is fully charged. If your Honda is affected by the recall, take it to the dealer to get it serviced. Honda issued a recall for this problem where a software update changed the behavior on TCU reboot. Low voltage can cause the TCM to reboot, which places the transmission in Park or Neutral. Hondas equipped with the latest 10-speed automatic transmission are very sensitive to voltage fluctuations. The dealer may inform you over the phone or require you to take the car to verify. Honda has developed a transmission software update that can prevent the lockup clutch from staying engaged.Ĭall your Honda dealer to give them your VIN and ask if there is a transmission software update. This condition puts unnecessary stress on the transmission and can shorten the life of the transmission. Honda transmission problems can also be caused due to TCM software keeping the torque converter engaged even when it is stopped. Honda Transmission Control Module (TCM) may malfunction. The TCC solid does not need to be removed from the vehicle it just needs to be disconnected.įollow this guide on how to perform a TCC lock-up solenoid test. This may be the problem if you are getting fault code P1735.īy meaning the resistance, you can perform a TCC lock-up solenoid test using a digital multimeter. The problem for Honda equipped with the four-cylinder engine could be the TCC lock-up solenoid. Honda TCC Lockup Solenoid Resistance Test 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. If you have a scanner designed for Honda, it is good to perform a full system scan that will read codes in all modules. Scroll down to Read Codes and press enter.Select the Automatic Transmission menu.Select your Honda model, then go to the Control Unit.Locate the OBD-II port under the dashboard.These scanners can read and clear fault codes from the transmission module. The YOUCANIC full system scanner can read and clear all codes on any vehicle’s control module. What you needĪ scanner that can diagnose Honda transmission problems. In addition to diagnosing the check engine light, your scanner must also diagnose the transmission module. Generic OBD2 scanners cannot read transmission fault codes. Transmission-specific fault codes get stored in the transmission control unit and will not always set the “check engine light.” Transmission problems will, in most cases, generate a fault code. The Honda transmission may be low on transmission fluid, including delayed engagement, transmission slipping, and rough shifts between gears. If the level is low, add the recommended amount of Honda transmission fluid. How to check transmission fluid on a Honda?Ĭheck the transmission fluid level as soon as possible. To prevent further damage, Honda malfunctioning transmissions should be diagnosed as soon as possible. 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. Symptoms range from delayed engagement, engine revving up, check engine light staying on, and “D” light flashing. Usually, one to two symptoms will be present depending on your Honda transmission problem. Thumps or clunks noises when changing gears.The engine revs up before the car starts moving.The transmission slips when changing gears.Symptoms of Honda transmission failure include: If coolant is mixed with transmission fluid, it will damage the transmission bands, requiring complete rebuilding. 201l5-2018 Honda and Acura vehicles with ZF 9HP 9-speed automatic transmissions were recalled due to problems with gasket leaks that allowed engine coolant and transmission fluid to mix. Newer models are not trouble-free either.
