I would recommend just wiring up the reverse solenoid to the E brake, I cut my spring and didn't like it. I also tried a lighter spring and that feels a lot better but I'm always afraid that I would throw it into reverse going from 4th to 5th, but that's just me.
Pure, I am lucky because in my car (FG XR6 TURBO) The manual comes in just the Tr6060 and the auto comes with the German ZF 6 Speed. Could you reply your thoughts. Aussie by the way
