HERE'S HOW WE MAKE THE 4L80E BETTER:

Pump and Valve Body Upgrades

We install an updated Sonnax valve body and pump to improve pressure control, shift quality, and reserve capacity.

Improved Sprag and Piston Durability

An updated, 34-element intermediate sprag and molded rubber pistons are installed to ensure optimal holding capacity and eliminate lip seal separation.

Upgraded Bushings

Every bushing is replaced with a new, custom-spec unit to optimize fluid flow and maintain stable pressures. We also install an upgraded, no-walkout rear case bushing with a flanged design to prevent it from slipping out of its bore - a known, damage-causing factory flaw.

Premium AFL Valves and Shift Solenoids

Our upgraded actuator feed limit valve and all-new shift solenoids ensure proper hydraulic pressure for positive shifting - no more missing shifts leading to limp mode.

Enhanced, Tested Torque Converter

Our fully remanufactured torque converter is rigorously tested for leaks, lock-up, concentricity, and balance - gone are the front seal leak, early bushing wear, and vibration issues common to the 4L80E.

HERE'S WHY OUR TRANSMISSIONS LEAD THE INDUSTRY

Every transmission we touch gets the same treatment:

Teardown and Triple Clean – Every transmission is disassembled, inspected, and cleaned three times. We also chase all threads and install all new bushings during this process.

Valve Body Rebuild and Test – Our most experienced team members rebuild and inspect each valve body before testing it using our C.A.R.S. testing system, which simulates real-world use and validates the valve body.

New O-Rings, Gaskets, and Seals – Once the valve body is tested, the transmission is reassembled with all new o-rings, gaskets, and seals.

Dyno Testing – Our custom dyno testing machines spin and load test every transmission to verify it’s ready for the road.
