Posted on by Amos

COMPLAINT: The vehicle may display a “Chatter” and/or a slipping condition when the selector lever is placed in the Reverse position. All forward gears are OK.

CAUSE: The cause may be, leaking of reverse feed oil, created by a bent or warped spacer plate, a bent or distorted l-2 accumulator tension plate, or the checkball that is retained by a sleeve in the l-2 accumulator housing not sealing because of debris and/or damage to the checkball seat in the housing. Refer to Figures 1 and 2.
