Sonnax Performance Pack HP-4R100-01 offers innovative, heavy-duty calibration for firmer shifts under load without sacrificing low-speed drivability. Precision components upgrade the 4R100 for maximum performance and durability by recalibrating pressures and shift accumulation. Durable, improved parts target commonly worn areas in the transmission to repair damage and prevent future wear and tear.
- Recalibrated shift accumulation, with tunability for great HD shifts
- Improved accumulator valves for greater clutch durability
- Improved pump components to minimize leaks and maintain pressure, TCC performance and lube
- Sure Lock overdrive retaining ring prevents loss of 4th
- Includes internal parts for setup and to prevent common failures
This year I have installed 4 of the HP-4R100-01 kits and have been so satisfied with the reaction of my customers that I installed one in my own truck. Great product! Thanks Sonnax!
