Transmission Over Temperature

WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.

Using the inputs, the ECM can detect if the transmission fluid temperature is too high. If the transmission fluid temperature and the vehicle speed are too high, a message will be displayed on the DIC to alert the driver the transmission temperature is hot and vehicle speed is to be reduced.
