A/T - 700R4 Snap Ring Jumps Out of Place

TSB 86-29 (June)

SUBJECT: 700 R4

COMPLAINT:

Reverse clutch retainer snap ring jumps out of place after rebuild.

CAUSE:

Retaining snap rings crossed during rebuild between the reverse input clutch and lo-reverse clutch. The size of these two rings is close enough that positive identification cannot be made visually by looking at O.D. only.

SOLUTION:




Check the thickness of the two snap rings. The reverse input clutch snap ring is .063" thick. The lo-reverse clutch snap ring is .054" thick.
