Automatic Transmission Pans from XDP, Mag-Hytec, and PPE will help extend the transmission fluid life by keeping it cool.

In older diesel trucks it is common for them to have a manual style transmission which requires the driver to do all the gear selections on their own. Find the parts you need to keep your transmission on the road with the products available at XDP. Valair or South Bend Clutch Manual Transmission Clutches are available with single, dual, or triple clutch plates to handle any power level.
