HARD SHIFT - 2ND GEAR LOCK-UP LOCK PIN

1984/1985 SUNBIRD, 1985 GRAND AM AND FIERO WITH ISUZU TRANSAXLE

If a condition of hard shifting or second gear lock-up is experienced on a five-speed manual transaxle after internal repairs, it may be caused by missing or incorrectly installed lock pins. This is especially true in the case of items #39 and #41 in the illustration. These two pins are slightly different in length and shape; and if installed in the wrong position, may cause one or both of the above conditions.

Item #39 Part #94250114 -------- --------------- Length .482" to .486" long (12.3mm) Cosmetic Difference Spherical Ends

Item #41 Part #94250116 -------- -------------- Length .510" to .514" long (13mm) Cosmetic Difference Conical Chamfer on each end.

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.
