4 Spd slight grinding when shifting.

hi, If it was stuck in reverse, then side cover is not aligned properly. loosen up side cover, shift trans into reverse, tighten cover down, now it will come out of reverse easier. prob find it will shift easier in gears. 1965 trans used a ball and detent side cover. the reverse arm has a shoe, which has to match the shoe on 1-2 arm for things to operate correctly. if not, it binds the shifting.
