Vehicles equipped with ZF5HP24 transmissions often suffer overheating, lube-related failures and TCC apply problems. These issues can be caused by excess wear in the lubrication valve bore, which allows crucial pressure to escape the circuit. Bring these symptoms under control and restore normal operation by reconditioning the bore and installing Sonnax oversized lubrication valve kit 139740-03K.
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
