CAMPAIGN: AUTO TRANS CONTROL CABLE ADJUSTMENT/RE-ROUTE
Subject: AUTOMATIC TRANSMISSION CONTROL CABLE
Models: 1992 G1, G2, AND G3 VANS
DEALERS NOTIFIED VIA DCS MESSAGE ON SEPTEMBER 12, 1991 TO STOP DELIVERY OF INVOLVED MODELS
General Motors of Canada Limited has determined that certain 1992 G-Vans, equipped with an automatic transmission, fail to conform to the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 102, "Transmission Shift Control Sequence," Starter Interlock, and Transmission Braking Effect." Some of these vehicles may have a mis-adjusted transmission control cable that, under a certain sequence of operation, allow the engine to be started with the transmission in gear. This condition could cause the vehicle to move in an unexpected direction and cause a vehicle crash without prior warning.
In order to comply with CMVSS 102, and to correct this condition, the shift cable routing will be inspected and the cable adjustment reset using a revised procedure.

SERVICE PROCEDURE:
INSPECTION:
----------- Inspect for a red/orange round sticker on the right hand side (passenger side) of the radiator support, next to the hood latch. If sticker is present, proceed to Step 28 below. If sticker is not present, proceed to "Repair Section" below.
REPAIR:
-------- 1. Inspect the cable routing past the brake pipes in the engine compartment to ensure routing is as shown in Figure 1.
NOTE: If the cable is routed correctly, proceed to Step 9.
2. If the cable is routed incorrectly, it will be necessary to remove the shift cable at the transmission end.
3. Remove the shift cable from the transmission manual shaft per Step 16 below.
4. Loosen the locking tab from the cable conduit per Step 17 below.
5. Using pliers, compress the cable conduit top and bottom, retaining barbs until the cable can be removed from the transmission retaining bracket. See Figure 2, Note 1.
6. Remove the cable from the retaining clips in the engine compartment.
7. Reroute the cable per Figure 1.
8. Reinstall the cable in the engine compartment clips, and into the transmission retaining bracket.
9. Remove instrument panel extension screws "A" (Qty. 2). See Figure 3.
10. Remove engine cover screws "B" (Qty 2). See Figure 3.
11. Release engine cover over centre latches "C" (Qty 2). See Figure 3.
12. Slide engine cover rearward until the seats restrict rearward movement.
13. Shift cable must be routed above spark plug retainer and bracketry and outboard past such items as rear A/C pipes, CIC servo and bracket, as applicable. Cable must be allowed to assume its natural routing.
14. Place steering column transmission shift lever in NEUTRAL position. For tilt steering columns, adjust the column 2 detents down from the full up detent position.
15. Observe and ensure transmission cable assembly is routed freely from the front of dash, past the brake pipes, and in the engine compartment as shown in Figure 1.
16. Remove shift cable nylon ball receiver from transmission manual shaft lever ball stud. See Figure 2 "B" Use screwdriver to snap receiver from stud.
17. With a stubby screwdriver inserted into slot at Point A, pry upward against the cable release until the cable is free to move in the adjust body.
Locking tab will move outward approximately 1/2 inch. It is not necessary to completely remove the locking tab. See Figure 2.
18. Install a #64 (3-1/2" x 1/4" x 1/32") rubber band on the steering column shift lever as shown in Figure 4 to preload it while ensuring it is in the NEUTRAL detent to its maximum clockwise position.
19. It is essential that the shift cable conduit slides freely in the adjust body. See Figure 2. Note 2. If the conduit does not slide freely, route the cable past any obstructions such as air conditioning pipes, spark plug retainer, etc.
20. At the transmission manual shaft, place the lever into NEUTRAL position (2 detents from PARK; PARK is full clockwise). See Figure 2 "B."
21. Attach plastic shift cable ball stud receiver onto transmission manual shaft ball stud with the flat side toward the lever as shown in Figure 2.
22. Push transmission shift cable locking tab back into its seated position. DO NOT touch conduit while locking the tab.
23. The shift cable system is now properly adjusted.
24. Remove rubber band from shift lever, and ensure vehicle will start only in PARK and NEUTRAL.
25. Reinstall engine cover.
NOTE: DURING STEPS 26 THROUGH 37 APPLY SERVICE BRAKE AND FEATHER RELEASE TO VERIFY VEHICLE IS NOT IN GEAR.
26. Position gear shift selector in Park.
27. Turn ignition switch to start engine. Engine should start, but vehicle must not move.
28. Position gear shift selector in Reverse.
29. Move selector toward Neutral to remove free play. Do not move out of detent.
30. Attempt to turn ignition switch to the start position. Switch should not turn.
31. Move selector to Neutral.
32. Repeat Step 27.
33. Move selector to Drive.
34. Repeat Step 29.
35. Repeat Step 30.
36. Repeat Step 3 1.
37. Repeat Step 27.
38. Verify PRNDL needle alignment. If adjustment of the PRNDL needle is required place steering column shift lever in NEUTRAL position. DO NOT change the alignment by readjusting the transmission shift cable or moving the PRNDL housing. The tilt steering column needle is adjusted by tapping the steel retainer sideways with a screwdriver; the standard (non-tilt) column needle is adjusted by loosening the pointer retainer screw and adjusting as required and retightening the screw.
39. Install Campaign Identification Label.
INSTALLATION OF CAMPAIGN IDENTIFICATION LABEL

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
