Overdrive Range, Second Gear: Notes

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

As the speed of the vehicle increases, the Powertrain Control Module (PCM) receives input signals from various engine and transmission sensors. The PCM uses this data to de-energize the 1-2 shift solenoid (SS) valve in order to shift the transmission into second gear at the appropriate time.
