Gearstar Performance Transmissions

transmission and converter are dyno-tested the equivalent of 100 mph on the street where we check hydraulic pressures, temperatures, shift quality, converter stall and lock-up. We make sure all shift points are at the correct RPM. When you receive your transmission and converter package, you can be sure it is functioning perfectly . Whether it is a Turbo 350 going behind a mild small block or a 4L85E built for a C5R blown LSX, the same expert technicians will be working on either package. At Gearstar, we approach each project as if it was going into our own car or truck.
