GR1500 Faceplated TREMEC T56 Magnum Transmission (trans only)
$ 8,395.00
The GR1500 (previously called "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.
Available in TREMEC Magnum, Magnum-F and Magnum XL spec! Choose your ratio below.
The Ford XL Magnums come as a complete kit for a bolt-in faceplated setup for your 2005-2016 V8 Mustang! I can also convert any Magnum XL to GM input for use in chassis that need the furthest back shifter location.
I also offer a strain gauge shifter to allow clutchless shifting on 1-4 gears!
Left: Factory synchro hub. Center: proshifted hub. Right: faceplated hub.
Transmission is available with/without 2JZ bellhousing and you will need to provide the tranmission mount and shifter on your own.
Close ratio: 2.66, 1.78, 1.30, 1:1, .80, .62
Wide ratio: 2.97, 2.10, 1.46, 1:1, .74, .50
