XDP has a large assortment of stock replacement and upgraded parts for the Transmission in your 2004.5-2005 GM 2500HD/3500HD. Hardened input, output, and intermediate Automatic Transmission Shafts are a massive upgrade for your stock transmission. DPC, Sun Coast Converters, and ATS offer Torque Converters that will handle competition-level horsepower and torque. Automatic Transmission Pans from XDP, Mag-Hytec, and PPE keep the transmission fluid cold, extending the life of the fluid. Enhance the shifting of your transmission with a Valve Body from Revmax, BD-Power, or ATS. Upgraded Flex Plates will handle more power and enable better power transfer from the Torque Converter.
A manual style transmission is typical in older diesel trucks, requiring the driver to make all of the gear selections on their own. Manual Transmission Clutches from Valair or South Bend Clutch come with single, dual, and triple clutch plates to handle any power level. Find the parts you need to keep your transmission on the road with the products available at XDP. Upgrade your transmission's input shaft with XDP's Manual Transmission Shafts.
