I've seen a lot of versions to how people have corrected a P0700 code on their trucks on this website and I'd like to tell you mine. I ended up having a burned up clutch in 4th gear that contaminated the rest of the tranny. Weird shifting and locking out of 4th gear was my problem. I bought the truck used and it started about 3k miles after I bought it with a minor slippage when the tranny was cold.

Anyone have this happen?
