Temperature Too High

Temperature too high

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

Other information:
- To replace the oil, see Transmission fluid, replacing Transmission Fluid, Replacing.

Resetting the adaption and oil quality counter





Resetting Transmission fluid change counter

Resetting Transmission fluid change counter

Hint: The transmission control module (TCM) has a counter for the oil quality. The counter counts up if the transmission is exposed to too high a load or an ambient temperature that is too high. If the counter is not reset when the oil is drained or changed, there is a risk that a diagnostic trouble code (DTC) will be stored in faulty circumstances. Therefore it is important that the "Transmission oil change" counter is reset.

Note! This applies only when the transmission fluid is changed and when the fluid is changed when repairs are carried out to the transmission temperature sensor.




- Ignition on.
Reset the counter by clicking on the VCT 2000 symbol.
