Chevrolet Performance Supermatic 4L85E 4 Speed Automatic Transmission
This new extreme duty GMPP 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 completely brand new transmission and contains no remanufactured parts or components and is a direct bolt-in for Gen I small blocks and all big blocks.
Features:• Additional heavy duty clutch plates
General Motors limited 12 Month warranty. Click on Document tab above for full details.
Note: Transmission does not include torque converter
