"If you can do a clutch job, you can install our kit."

Thank you for your inquiry about the conversion of a Toyota Celica/Supra (1983 to 1985) W58 5 speed transmission into your Triumph (TR2,3,4,or 6). I developed over the last 5 years for use in two of my TR-3s. Friends in our local Triumph Club (DCTRA) asked if I would help them make the conversion, and now I have done many. The 5 speed conversion will allow you to cruise at freeway speeds with less worry about the strain on your motor. The Toyota transmission has proven to be reliable and requires very little maintenance. The conversion utilizes STOCK TRIUMPH hydraulic clutch parts (Pressure plate, clutch slave and linkage, throwout bearing, and cross shaft and fork.) I suggest that you seek out professionals to do the conversion. The process is fairly straight forward, using Triumph hydraulic clutch slave, pressure plate, throwout bearing, and the parts that we furnished. You will be able to bolt in a Toyota 5 Speed Transmission. No welding or machining needed.
