So my 6 speed is giving me some problems already, the one thing that I thought wouldn't be a problem and the big reason why I custom ordered the truck!

For years and intermittent metal clanking noise when taking off - like a couple tin pie pans banging together a couple times. but worked fine up until recently a big 'crunch' in parking lot and then weird shifting all the way home - would not go into reverse or L at all. Shifting felt gritty like something was blocking the path of the shifter. Also cruising around parking lot there was noticable drag, even with the clutch in, if it was in gear there was drag. Popped out of gear and no drag. Some random hard shifts. Then next day, all seemed fine? Goes into reverse and L again, though maybe with a bit more effort. Obviously something major wrong in there still. I don't trust it especially on out of state trips until I get the internals looked over.

Looking for someplace hopefully between Columbus and Mt Vernon area.

Thanks for any recommendations!
