We;lcome to the site Blown2V. I also have an '03, but mine is the Mach1. I had to have some work done on my 3650 Tremec transmission to allow me to go from 2nd to 3rd in a racing situation. It simply hit a wall and would not engage. So, I had a heavy duty clutch installed along with all new heavy duty syncronizers and a short throw shifter. It slides into 3rd every time now. That heavy duty clutch plays hell with my left leg in heavy traffic though. I used to live and work in Alief. I do not miss the traffic of Houston.
