Shift Controls

The Hydra-matic 4T60-E uses two ON/OFF shift solenoid valves with a 2-port design that provides for all forward gear ranges. These shift solenoid valves work together in a combination of ON or OFF sequences to direct fluid pressures to the various shift valves and apply components. The following table shows the solenoid state for each gear range.

Park, Reverse, Neutral
Solenoid 1-2 ON
Solenoid 2-3 ON
