About 4R100 Transmission
Rated at up to 1000 lbs. per foot of torque, the 4R100 transmission is one of the toughest automatic transmissions available. Ford debuted it in 1999 and began to phase it out after 2003, but odds are, your Ford truck is still going strong. However, if this beast of a transmission has already served you well and it is time to replace it, begin by searching the vast inventory on eBay. Look for 4R100 7.3 transmissions with brand-new gaskets, seals, sealing rings, clutches, bands, pump bushings, and solenoid packs. In addition, many feature upgrades to the boost valves, pressure regulators, and snap rings. Steel accumulator valve kits and shift valves complete the durable, tough-as-nails package. Consult your repair manuals to make sure you find the transmission that fits your Ford's model, year, trim, and specifications. Rebuild kits are also available, featuring splined forward crutches, steel modules, gasket sets, molded pistons, bands, filters, and bushing kits. Regardless of whether you replace or rebuild your 4R100 transmission, you can have your Ford back in its top shape in no time.
