No I haven't had the trans out, yet. actually is still sitting on the trailer, (easier to get underneath) and we still had snow on the ground till last week here in MI.
don't know either, Bought the truck from a guy in MO, was an old guy down the roads truck was running till mid late nineties then sat in a open shed. don't know why it was parked.
fairly obvious that its was kept inside most its life the underside, cab, frame and mechanicals are clean and solid.
I have Heard of complete clutch diaphram failures but never seen one. I was hoping to get some ideas before rolling it off and commencing to tear into it.
