Has anyone done a Mk 10 modern manual trans conversion? Possibly a 6 speed? Considering performing one on my 1963.
Lots of cars came from the factory with manual 4-speed + overdrive, works well and is a pleasure to drive.
Not over here in the states they didn’t. 4 speed manuals with overdrives are hard to find. I’m looking for a manual gearbox pedal assembly for a Mk X right now as well.
A modern 5 or overdrive 6 speed that would fit would be great!
The common one I have heard about is a Tremic. Believe they are 5 speeds. Should fit OK as manual are usually less bulky that automatics but you still have to find a pedal box, clutch master, and pedal and may have to shorten or lengthen the propshaft. Once drove an XK150 with one of these boxes and it worked very nicely.
I did a conversion in a V12 XJ, some of the boxes can handle a lot of torque
You do need to source and/or modify many items such as flywheel, pedal box, clutch plates, clutch actuating cylinders, tailshaft, speedo, etc etc
Maybe the Tremec would be better for USA, but I believe there are similar issues with fitting one of them as well
A rusty donor manual XJ would be another alternative
