REV. ACCUMULATOR BUSHING AND RETAIN CLIP/CONV. CLUTCH REG.

SUBJECT REVISED ACCUMULATOR BUSHING AND RETAINING CLIP/CONVERTER CLUTCH REGULATOR LINE-UP

MODELS/YEARS 1993 VEHICLES EQUIPPED WITH THE 4T60-E (RPO M13) TRANSAXLE

A redesigned accumulator bushing and accumulator bushing retainer clip has been released for all 1993 HYDRA-MATIC 4T60-E transaxles. The redesign has improved the 'holding' capacity of the accumulator bushing by increasing the bushing retainer window to accommodate a more robust retainer clip (380).

Also, a new design has been released for 1993 on the 4T60-E transaxle "Converter Clutch Regulator" line-up. The new design has eliminated the valve bore plug (329) and spring clip retainer (314), and replaced them with a converter clutch regulator bushing (384). The bushing is secured in place with converter clutch retainer (383), which was previously retainer (337).

The revised accumulator bushings and accumulator bushing retainers were implemented into production at the start of the 1993 Model Year (SVP 93). When servicing prior 4T60-E transaxle models (1991 and 1992), it is essential that the old (prior) accumulator bushings and accumulator bushing retainers be used (THE OLD AND NEW ACCUMULATOR BUSHINGS AND RETAINERS ARE NOT INTERCHANGEABLE).

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.
