Well i was sealing gaskets on the engine and took it out for a test run. I got back and parked the truck and let it run hopeing i had solved the problem. Thinking I had, I moved it back to its parking spot. Went to put the truck in reverse and the shifter never clicked when moved it from drive to reverse. And it was still in drive. Got under the truck pulled linkage apart off tranny and moved it no clicking sounds moves real smooth like. Since it decided to drift onto my mothers blue berry bush i had to move it. So I got my pickup to pull it back Turned out that it still has park and drive(or atleast first) Did the linkage inside the tranny come apart? Is that possible? I haven't hardly done anything hard with it since I built it last Summer. Oh ya TH350 tranny. Any Help Greatly apreciated.
