Transmission Mode Switch: Description and Operation
Shift Mode Switch In Center Console
Wiring Diagram
PURPOSE
The transaxle shift mode selector switch is used on the automatic transaxle to allow the operator of the vehicle to select a normal or performance
(aggressive) shift schedule.
OPERATION
The Norm/Perf switch is a simple On/Off switch. The PCM supplies a 12 volt signal to the Perf/Norm switch. When Perf mode is selected the
PCM circuit will be pulled to ground. When the switch is in Norm mode the circuit is opened and the PCM pin will be at battery voltage.
Initial shifts after a cold start are completed in normal mode even if the performance mode is selected. Performance shift schedule timing and
pressures are based on learned normal mode shift characteristics.
LOCATION
The switch is located on the console near the gear select lever.
