I recently brought my Bullitt to the dealer to have the 1-2 shift fork replaced. When I got the car back, nothing had changed, it was still grinding on the 1-2 shift when cold. The dealer is in the process of ordering a new synchronizer. Here's my thought, if the tranny is only grinding when cold, wouldn't that be a problem with the fluid, and not a mechanical part? The tranny works fine when it's warmed up. So, what has changed? As far as I know, the only thing that has changed would be the viscosity of the trans fluid. I also remember reading that some people here have had good results when they changed to a syntheteic tranny fluid. What do you think?
