I have been using Gearstar transmissions for the better part of 15 years, in many of the projects here at SportsFab in Milford MI. Not once have I ever had one come back defective, in any way!

MICHAEL BEGLEY

You would be hard pressed to find a group of guys that know more about transmissions. We are blessed to work with them, and they build a quality piece that you can always count on.

BRIAN DOWANRD

Gearstar provided me with one of the best automotive purchases I’ve ever made. A custom built 4L80E transmission for my 800 HP street / Strip Camaro. Highly recommended if you want the best.
