The GR1000F is a faceplated T56 Magnum featuring faceplated gears on 1-4, custom billet shift forks, cryogenic treatment of the gearset, and rem polishing of the gearset. The process starts by taking a brand new Magnum transmission direct from Tremec, disassembling and removing the factory synchronizers. These are replaced with hubs that have 7 teeth. This makes engagement unbelievably quick.

I also offer a strain gauge shifter to allow clutchless shifting on 1-4 gears!
