This bulletin is being written to correct the procedure when checking the Oil Pump to High Clutch Hub Shim Adjustment.
Step number 3 on Page 7A2-38 of the 1990 GEO Storm Service Manual should read:
3. Place the J 35284-1 bridge and leg assembly, J 35284-19 bridge extension with J 35284-4 gage cylinder and a J 35284-32 high clutch gage pin on the transaxle case (Figure 132).

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.
