BULLETIN COVERS
A new control valve assembly with a new 1-2 accumulator spring, valve and bushing went into production to reduce the potential for a harsh 1-2 upshift.
This upshift may occur during wide open throttle in a 1988 N car equipped with a KDC model THM 125C transaxle. This condition may be repaired by
installing a 1-2 accumulator valve train.
