Hey guys. I've now driven my '70 sporto for about 2500 mi and have swapped out the tranny fluid for synthetic royal purple which helped smooth out the shifts greatly. The only problem I still have is that after not driving the car for a few hours (say overnight), it grinds when shifting into reverse. After a block, it doesn't make a grind whatsoever when shifting back into any gear from neutral. Any suggestions? RPM is fairly low when cold, ~750 rpm and idles smoothly. The car has only 91k original miles.
