The 1984 OZ model 200-4R transmission used only in the Hurst/Olds does not use a 3-4 accumulator spring. Please correct your 1984 Cutlass Supreme Chassis Service Manual on page 200-4R-11, Fig. 200-4R-17 to indicate the spring is not used on the 1984 OZ model.
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.
