Ex,
Now a little more confused. Pulled the top off the box and drained the gear lube. Thought I would at least see the culprit... but no luck. Everything looks fine...synchros centered and detents working. I gathering that by the reverse pin you mean the interlock pin that goes into the shift rail for 3rd and 4th. Can't really tell if that is in but the tranny doesn't seem to be selecting multiple gears. Reverse idler and slider seem to pull back fine but...I did find somethin' unusual. With the tranny in neutral, I can easily move the reverse cam with your hand and move the reverse gear. It would seem that the detent is not in or no spring in:confused confusedthe reverse shift rail. Everything seems centered and adjusted perfectley. No metal or telltale came out when I drained the gear lube. I did find my speedo problem which quit working after a few minutes of driving.. speedo gear flattened out. Obviouisly need the oddball reverse cut nylon speedo cable gear. Still stumped. Its like the main shaft is bound up in the tail section but reallly don't understand what could cuase that other than a massive rear bearing failure.
