MY1982 GMC RTS Coach with an Allison Automatic Transmission

Customer Question

MY1982 GMC RTS Coach with an Allison Automatic Transmission was running fine. After being in storage for about three years it suddenly stopped shifting into drive. It shifts fine in the lower gears. at about forty miles per hour the engine suddenly slows down and the transmission shifts into second gear and stays there and maintains a constant speed of about thirty miles per hour and stays at that speed. It stays at that speed. Any ideas what the problem could be? I have had it in several shops including Detroit and no one has beenable toggle me an answer what the problem could be.
