Chevrolet Performance Supermatic 4L85E 4 Speed Automatic Transmission

This extreme duty CPP transmission is built by GM using their already heavy duty 4L85E transmission with the addition of extra clutch plates, increased fluid pressure, and a revised firm shift valve body. The Chevrolet Performance staff then took this transmission and validated it against their ZZ572/720 HP / 685 Ft. Lb. torque engine and found that they could not break it! This is a direct bolt-in for Gen I small blocks and all big blocks.


• Additional heavy duty clutch plates
• Direst bolt-on for small and big block Chevy engines
• Improved and revised valve body calibration
• Gear ratios: 1st 2.48, 2nd 1.48, 3rd 1.00, 4th .075

General Motors limited 12 Month warranty. Click on Document tab above for full details.

Note: Transmission does not include torque converter
