This bulletin is being reissued to correct the year identifying the revisions that were made to the snap rings.
THM 700-R4
Beginning September 1, 1982, all THM 700-R4 transmissions were built with a revised design snap ring for both the reaction sun gear and the lo and
reverse spring retainer to case (see illustration below).
When disassembling or inspecting any THM 700-R4 transmission, it is not necessary to remove the snap ring from the reaction sun gear unless you
intend to replace it.
When servicing any THM 700-R4 transmission reaction sun gear or lo and reverse spring retainer to case snap ring, replace it with P/N 8647337. When
installing the snap ring, do not over expand it.
