Description
Our many 42RE performance enhancing upgrades
Our remanufactured 42RE transmission is built for performance and durability, featuring a fully upgraded valve body, throttle valve, manual valve, four-spool switch valve, pressure regulator, and governor plugs. The enhanced valve body is engineered to keep the torque converter charged even in park, boosting longevity and improving shift performance. A high-performance torque converter ensures optimal fluid control, improved balance, and superior power distribution—surpassing OEM standards. Our precision-machined pump eliminates slippage and maintains equal internal pressure, while the custom eight-plate clutch pack and new thrust plate significantly enhance durability under load.
To further increase reliability, we polish critical bushings to a 16 RA or better mirror finish, improving pressure retention and internal efficiency. Each transmission includes a Hayden external fluid cooler for a limited time, reducing heat and extending the life of your unit. Custom-machined output shafts are compatible with both early and late-style yokes, while the oversized reverse brake strut eliminates clearance and drum slippage issues. A heavy-duty five-pinion planetary gear set gives the 42RE exceptional torque-handling capability. Every transmission is dyno-tested and performance-verified before shipping, ensuring you're getting a product that's built to perform and built to last.
