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

FIRST
Solenoid 1-2 ON
Solenoid 2-3 ON

SECOND
Solenoid 1-2 OFF
Solenoid 2-3 ON

Third
Solenoid 1-2 OFF
Solenoid 2-3 OFF

FOURTH
Solenoid 1-2 ON
Solenoid 2-3 OFF
