4L70E Transmission Rebuild Kit Parts

The GM 4L70E transmission is a 4-speed automatic transmission that offers the ability to withstand more horsepower and greater torque capacity than the 4L60E and 4L65E designs. The 4L70E was originally only fitted for half-ton GM trucks and SUVs, but is commonly found in street rods and muscle cars due to its ability to be easily adapted. Raybestos Powertrain offers premium friction materials like the Gen2 blue, GPZ, and Stage-1 friction clutch plates to help the 4L70E transmission go above and beyond its potential as a stock unit.
