We just completed this Toyota 5-speed transmission conversion for a client on his 1971 Triumph TR6. The kit we used was supplied by Herman van den Akker of HVDA Transmission Conversions. Herman has done an excellent job of putting these kits together and the installation was very straight forward.
We are usually not big fans of doing 5-speed conversions but as overdrive transmissions are getting harder to find, and prices are going up and up on the transmissions and parts, this may be the best route to go in the future. When Herman’s kit is installed, you visually can’t tell that the car has been updated with a 5-speed.
The transmission mounts in the original tunnel with plenty of room to spare and the shifter is placed in the same location as the original. On the road, the Toyota transmission is nice and quiet and it is sure great to be able to put it in 5th gear and watch those rpm’s drop. Please feel free to post any comments or questions you have.
