P0736

2017-10-10

Description:

  • 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
