AW55-50/51SN / AW50/51 Transmission

Temperature too high

Checking the wiring and component
The diagnostic trouble code (DTC) was caused by the transmission being subjected to high loads and high temperatures. It is therefore important to change transmission fluid and to check the function of the transmission.
Replace the oil according to Gearbox fluid, replacing Removal and Replacement.

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.
