i have a 68 mustang with a efi conversion 5.0 ho and a t-5 swap. well the trans was doing great for 500 miles. then i got on it for a bit and now 1st and 3rd are harder to go in to gear. the shifter is a pro 5.0. im guessing mabey a bent shift fork but im not as familliar with the t-5. thanks in advance
