TCC Light Pulses (Flashes) when in Reverse

Created by Craig Morton, Modified on Wed, 27 Oct, 2021 at 9:25 AM by Craig Morton

Applies to the A750 Transmission


When moving through the garage shifts ie: Park into Reverse, the Lockup module detects reverse and disables the Lockup Solenoid in the transmission. This is to avoid a situation where the transmission will make a loud gurgling sound that customers interpret as a problem.


The customer will see that the TCC light will pulse for the duration of the time the vehicle is in Reverse and stop six seconds after the vehicle comes out of reverse.


This is expected bahaviour
