is this a tranny problem?
 

is there a way to know if what im havin is tranny problem?
well right now i changed the clutch cuz i thot it was the clutch but the truck wont still run when revved..i checked the set screws & all are intact...so now im guessing its either the diff or tranny..how can u tell which is which?the only problem is truck wont moved when revved

does the truck roll freely when shut off

yeah it rolls freely ..also rolls a bit while engine is running but wont run

Eliminate some things. When you rev it, does the clutch bell put power to the spur? If the spur is getting power, then check the output shafts. If they are not spinning when you rev it, then its in the tranny. If they spin, and the truck still doesnt move, then you somehow blew both diffs. Highly unlikely though.

thanks guys ..i found out it was the nut that holds the spur keeps backin off even if i tighten it ...
