BULLETIN COVERS:
A redesigned accumulator bushing and accumulator bushing retainer clip has been released for all 1993 HYDRA-MATIC 4T60-E (RPO M13) 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 (Figure 2). 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).
DATE OF PRODUCTION CHANGE:
The revised accumulator bushings and accumulator bushing retainers will be 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).
