I installed a BM ripper shifter about 2 months ago with no problem, ran well pushed the car hard between now and then just fine but just today, my c5 keeps slipping out of first gear for some reason. All the other gears work ok, but i had to start off in second just to get home today. The first gear though either slips out (even when im pushin to keep it in) or slips and grinds. Any ideas? Im about to take the console apart and try to figure out whats going on tonite
