Our most popular performance transmission, we have been modifying and improving this trans since it was first introduced in the early 80’s. We offer several versions of this trans for applications up to 575 horsepower. This trans has a low first gear ratio of 3.06 to 1 and an overdrive ratio of .70 to 1 which translates into stump pulling low end and a 30% reduction in cruise rpm.
This trans was built with a Chevy only bolt pattern, but we have a package for Buick, Olds, Pontiac, and Cadillac people so you can enjoy the benefits of this excellent transmission too.
We also provide a custom rebuild service for those interested in keeping the original trans but need an upgraded version to handle additional power mods. Call for more details.
