The truck shows 266,000 miles and I don't know if the tranny has been gone through, and I've only driven it about 10 miles so all I can really say is it shifted nicely for me and didn't make any wierd noises. I could take it down my road and back just to double check if need be. I'm up in Redding area. If you have any friends who need parts it would be easier for me to sell the whole truck. It has a recent engine (around 30,000 miles) but the carb needs to be rebuilt.
