So about a little over 1000 miles ago, I replaced the entire clutch system in my 2012 GT Mustang including the Pilot Bearing, Throwout Bearing, Flywheel, RST Twin disk clutch, and Clutch line. I also followed up with a Barton Short throw shifter with Two Post Bracket. After installing everything, it was literally impossible to shift any gears until forcing everything into place for at least 1 day. Since then it has been very difficult to shift into first and reverse, but the other gears(2-6)...
