How’s your car clutch working? I have the same problem with my 07 gt500 with a new rst. Just don’t know what to tell my mechanic who installed the clutch for me.Got the car back today from a local transmission shop owned by a friend of mine. It finally shifts like it should, no trouble getting 1st or reverse at all, and shifts buttery smooth. What finally fixed my problem? 40 thousandths shims between the flywheel and pressure plate. Sounds strange, but it seems to have worked. I have a trackday this Sunday the 21st at Pocono with Hooked on Driving, will let you know how the car performs.
