What P0736 means
- The fault code P0736 indicates that there is an incorrect gear ratio detected in the reverse gear of the transmission. This fault code typically points to a problem with the transmission, such as slipping, gear synchronization, or a malfunctioning shift solenoid specific to the reverse gear.
Possible symptoms
- Malfunction Indicator Lamp (MIL) or Check Engine Light illuminated
- Transmission slipping or hesitation specifically in reverse gear
- Difficulty engaging or disengaging reverse gear
- Harsh or delayed engagement of reverse gear
- Decreased reverse driving power or torque
- Potential overheating of the transmission
Possible causes
- Low transmission fluid level or contaminated fluid
- Worn or damaged transmission components, such as clutches or gears in the reverse gear
- Faulty shift solenoid or pressure control solenoid specific to the reverse gear
- Malfunctioning torque converter
- Internal transmission damage or mechanical failure specific to the reverse gear
- Incorrectly programmed or calibrated PCM
Related parts
- Transmission Shift Sensor: Gear Shift Sensor communicates the position the gear shifted to. Problems lead to difficulty in shifting gears
Possible solutions
- Check the transmission fluid level and condition, and add or replace the fluid if necessary
- Inspect the transmission for any signs of damage or wear in the reverse gear components, and repair or rebuild as needed
- Test and replace any faulty shift solenoids or pressure control solenoids specific to the reverse gear
- Test and replace the malfunctioning torque converter, if necessary
- Perform a thorough diagnostic of the transmission to identify any internal damage or mechanical issues specific to the reverse gear
- Ensure the PCM is correctly programmed and calibrated for the specific transmission and reverse gear
