"When I pulled the top off it I found that first gear on the countershaft assembly was missing about half its teeth."
Yeah, I reckon that's a pretty good indicator of a bad tranny! LOL
As far as seat springs go, I'd say the seat is ultimately the most important part when it comes to a truck's drivability - both the truck's, and yours!
Sounds like real progress . . . I'm impressed, and envious. Thanks for the update. Best of luck.
