4T65EV Transmission

Temperature too high

Checking the oil cooler and hoses
The cause of the diagnostic trouble code (DTC) was insufficient oil cooling in the transmission. Check the oil cooler and hoses for signs of damage and blockage. Then replace the oil.

Other information:
- To replace the oil, see Gearbox fluid, replacing Removal and Replacement.

Resetting the adaptation





Resetting the adaptation

Resetting adaptation and the counter for "Transmission oil change"

Hint: The transmission has torque controlled adaptive pressure control. Pressure control means that the transmission regulates the pressure itself during each gear shift. This avoids harsh gear shifting. Each gear shift is evaluated by the control module and stored in the memory. This allows for compensation for wear and tear in the transmission and clutch. It is important that the adaptation in the memory is reset after the transmission has been repaired. This is to ensure normal operation. The oil is replaced during repair; the "Transmission oil change" counter must be reset. If the counter is not reset when the fluid is drained and replaced, there is a risk that a diagnostic trouble code (DTC) will be stored in incorrect circumstances.

Note! This applies only if the transmission or one of the components in the transmission have been replaced.




- Ignition on.
Click on the VCT2000 symbol to reset the adaptation and counter.
