Family Owned & Operated for over 50 Years!
The Automatic Transmission Clinic actually began in Grand Rapids Michigan by Robert Longstreet. He brought the business to our current location in 1961. In the early 1970s Bob added Kalamazoo Marine Gear as a second company in the same building. The company quickly became know through out the world for rebuilding outstanding marine transmissions. Mark Gernsback, a long time employee, became a partner and eventually full owner of both companies when Bob retired in the late 70s. Craig Lynn was hired by Mark in 1978. After taking a few years off to learn more general mechanic skills, Craig came back as a partner. Mark retired in 2008 and Craig took over as sole owner. We at the Transmission Clinic pride our selves in providing an outstanding product for a fair price.
