Odd shifter problem, need advice

More then likely you have the wrong pedal assembly for your pressure plate. Change the pin spread from 5 1/4 to 6 inch. You will get more release of the pressure plate. This was changed due to the the complaint of pedal being harder to push with the 6 inch spread. This can be done by welding 3/4 inch extension on yours. It will shift easier. Especially into reverse and first
