I live in Tampa and have had 2 transmissions rebuilt by a company called Zeigler Transmission. They are in a town called Oldsmar... right next to Tampa. They do excellent work. My transmissions were for my vehicles, but I see them working on trucks and RV's all the time. It's worth a call. They even give a nationwide warranty which is good for travelers.
