Tool required and sold separately. Wear is commonly found at di errant areas in the ZF5HP24 pressure regulator valve bore. Wear at the inner portion of the bore causes high pressure spikes leading to broken drums, pistons or other parts, as well as restricting converter/lubrication ? ow. Wear at the spring end of the bore allows line pressure to exhaust resulting in low line pressure, soft shifts and burnt clutches. ? The Sonnax oversized pressure regulator valve kit 139740-01K restores valve-to-bore clearances so the pressure regulator valve can maintain correct pressures. Features & Benefits: Annular oil grooves support the valve and reduce wear rate. Restores valve-to-bore clearances maintaining correct pressures.
