This product is used for the removal, installation and moving of heavy duty diesel truck transmissions. It has a universal adjustable saddle with four brackets that can be lined up with transmission pan configurations. Two safety chains and adjustment hardware are able to secure the transmission to the jack's saddle. It has a wide chassis for load distribution and stability, which also includes integrated trays to hold tools and hardware. The overload and bypass safety valves prevent the jack from being used beyond its rated capacity and ram over extension. A conveniently located release valve knob allows for slow, controlled lowering of the load. There are also four grab handles for jack repositioning.
