IV. Harsh 3-2 Shift Maneuver at 17-20 MPH

Service Action:
At start of production (SOP) 1987, an orifice pipe was added between the 1-2 servo release cover plate and the 3-2 coastdown valve to allow a smoother
second gear apply. The four new parts installed as a set will service certain past model transaxles with a harsh 3-2 shift maneuver condition.
