HERE'S HOW WE MAKE THE 8L90E BETTER:

Eliminate TCC Shudder

We install a fully remanufactured torque converter with an upgraded feed and pressure limit valve to eliminate the torque converter clutch 'rumble strip' shudder common to the 8L90E.

Valve Body and Accumulator Updates

All new accumulators are installed in the valve body, clutch control valve bores are refurbished, and a new pressure regulator valve (with boost valve and sleeve) is fitted to eliminate runaway line pressures.

Improved, Tested Solenoids

Solenoid pressure switches and seals are replaced to prevent the electrical communication errors that lead to limp mode. Our proprietary in-house temperature-controlled testing ensures every solenoid delivers OE+ flow rates and shift control.

Complete Bushing Replacement

We replace 100% of the bushings with new, custom-spec bushings to improve fluid flow, stabilize pressures, and restore hydraulic integrity.

Heavy-Duty, Towing Upgrades

Heavy-duty applications can be upgraded to use a billet converter with triple disc internal clutch to increase torque capacity and prevent slip under load.

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.
