Jaguar 5 speed Conversions

The VJT5 5 speed is the first 5 speed conversion for Jaguars that maintains a factory fit that requires no cutting. This 5 speed is based on the Borg Warner World Class T5 5 speed platform. It is assembled using components to make fitting in various Jaguar applications possible. Currently VJT5's have been installed in XK120-150, E-type 6 cylinder, E-type 12 cylinder and the Mark II saloon. The shifter locations remain where Jaguar intended them to be. Because these units are hand assembled with closer tolerancing, they perform much better than the production transmissions used in Mustangs, Camaros and Firebirds. Special input shafts are used to keep standard Jaguar pilot bushings, and special tailhousings and output shafts are used to bring shifters out in the proper location. Converting to VJT5 allows for cheaper replacement parts and longer parts availability.

We also make E-type 5 speed knobs and billet racing shifters for that special touch!


The VJT5 is fully synchonized in all 5 forward gears. It has a non synchronized reverse gear. All mainshaft gears are on needle bearings and all blocking rings except for 5th gear are of fiber composition with a dual cone design on 1st and 2nd gear. The weight of a 6 cylinder VJT5 is 68lbs. These gear sets are rated at 330 Ft. Lbs. static torque.
