NAG1 Automatic Transmission
Brake/Transmission Shift Interlock Mechanism - Description
DESCRIPTION
NOTE: Some shifter assemblies may have a small external trim cover to actuate the Brake Transmission Shifter/Ignition Interlock (BTSI).
The Brake Transmission Shifter/Ignition Interlock (BTSI) is an electronically operated system that prevents the transmission gear shifter from being
moved out of PARK without the proper driver inputs. The system contains a solenoid that is integral to the shifter assembly. The solenoid permits shifter
movement out of PARK when the brake is depressed and prevents shifter movement into REVERSE unless a shift into REVERSE is permitted.
A BTSI override (2) is provided on the side of the shifter mechanism (1) to allow the vehicle to be shifted out of PARK in the event of an electrical
failure.
