Section: 7 - Transmission

Bulletin No.: 67-71-40A

Date: September, 1996

NOTE: This bulletin supersedes Technical Service Bulletin number 67-71-40 dated April, 1996.

VEHICLES AFFECTED

1995-96 Chevrolet Camaro and 1995-96 Pontiac Firebird with HYDRA-MATIC 4L60-E Transmission (RPO M30).

CONDITION

Some owners may comment that during cold ambient temperature conditions the ignition key may be difficult to remove when the transmission is placed in the park "P" position. This condition may be temporarily resolved when the shifter lever is wiggled several times.

CAUSE

The park lock cable assembly may bind due to shifter assembly geometry thereby not releasing the ignition key. In addition, the "brake transmission shift interlock" (BTSI) solenoid may bind due to interference between its wiring connector retaining strap and the ashtray and/or due to cold ambient temperature conditions.

For Pontiac vehicles only

- The sliding tape close out in the console trim plate assembly may also interfere with the BTSI solenoid causing it to bind.

CORRECTION

Revised transmission control assemblies are available to address the binding conditions. These shifters have revised stampings. In addition, the "brake transmission shift interlock" (BTSI) solenoid rod has a revised coating to improve sliding characteristics.

Replace transmission control assembly per Section 7A of the applicable Service Manual. See parts information located at the end of this bulletin for applicable part numbers.

NOTE: In order to prevent binding, insure all excessive cable lengths are routed away from the shifter assembly and the wire harness which passes in front of the shifter assembly is not holding the cables up off the floor pan. Also remove section of orange retaining strap between the BTSI wiring harness and the retaining tab.

NOTE: DO NOT REMOVE Retaining Tab From BTSI wiring connector.

For Pontiac only

- The revised trim plates have additional material clearance from the closet tape to eliminate the interference with the BTSI solenoid. Replace console trim plate assembly per Section 8C of the applicable Service Manual. See PARTS INFORMATION located at the end of this bulletin for applicable part numbers.
