T 18 Top Cover parts kit
My T18 , If not dead on with the shift from 3rd to 4th, would fall into the reverse gate and I would get a grind, I figured the plunger spring broken, or collapsed .purchased the kit, Installed , had everything needed to rebuild the top of the shifter box, Spring in the reverse gate was broken , and a new one was included . Tightened this old box right up, A+ rating
