4R100 Transmission and Torque Converter
The 4R100 build process and upgrades have made this transmission of the strongest in the industry. Here are just a few of the things we have done to give this unit superior performance and durability. Our 4R100 transmission features a heavy-duty recalibration kit installed to reduce slippage and increase durability. We use upgraded locking snap ring for coast dutch and spiral lock snap ring for clutch address OE design flaws and eliminate premature failures. A 4R100 one piece rear case bushing improves internal fluid flow and lubrication. We feature a center support that has been machined and modified to accept a snap ring. The new pressure regulator and boost valve system eliminates delayed engagement, shudder, and 5.1) ft shifting.
Every 4R100 utilizes our Tru-Flat stator qualification and machining process. Each unit features a completely upgraded long-spline center shaft drum on all diesel and V10 units. An upgraded HD billet single-clutch torque converter is on all diesel and V10 units. A completely remanufactured pump with new line bore bushings eliminates leaks and provides superior flow and durability. Every 4R100 torque converter is tested for leaks, lockup, concentricity, and balance. These upgrades exceed OE requirements and eliminate the possibility of front seal leaks, premature bushing wear, and vibration. Our all new performance-spec bushings improve internal fluid flow control and pressures. Every bushing and machined surface are polished to a mirror-line OE finish of 15 RA or better.
