Developed by Chevrolet Performance engineers, the 4L75-E Supermatic has been proven, in real world conditions, to be one of the most robust automatic transmissions on the market. Featuring a torque capacity of 650 lb.-ft, this makes the 4L75-E suitable for many of Chevrolet Performance's most powerful crate engines. The Supermatic 4L75-E is the size of the 4L65-E transmission so it's smaller than the 4L80-E but offers more torque capacity than comparably sized product offerings. The 650 lb.-ft. torque capacity makes it the flexible alternative to the 4L80-E when transmission tunnel clearance is an issue.
