Continuous oscillation of the accumulator pressure control valve in the cast-aluminum body causes bore wear, which can affect accumulator control pressure. Wear at the balance port area can prevent the valve from stroking properly, which causes too much resistant pressure to the accumulator pistons and results in harsh shifts. Wear at the outboard spool can allow line pressure to leak to exhaust, resulting in decreased accumulator control pressure and soft shifts. The oversized Sonnax accumulator pressure control valve for the '95-'97 AX4N, 36948-20K, allows the worn valve body bore to be refurbished and restores pressure control to the accumulator control pressure circuits.
Reamer kit 36948-TL is no longer in production but may be available from distributor inventory.
