GearStar Ford E4OD/4R100 Level 4 transmissions come with a custom billet Yank Performance multi-disk lockup torque converter. This is the first of many upgrades that go into making sure that each transmission is not only built for performance applications to handle up to 700 crank horsepower or 650 crank-foot pounds of torque. This is a perfect option for heavy towing applications, featuring expanded capacity forward, direct, intermediate, and overdrive clutch packs. Level 4 units have a hardened drive shell, high volume pump, custom-machined intermediate and overdrive pressure plates; and they include a Transgo valve body reprogramming shift kit with shift command. These transmissions come with all new electrics, including the wiring harness, all sensors and solenoids—along with all new bushings, bearings, and seals. Every transmission is assembled by one of GearStar's five expert builders. The transmission packages arrive dyno tested with 100 miles already on the product, which means the break-in procedure has been done and they're ready to go! Select the model with options preferred for your vehicle.
