I prefer a built auto for towing.I am not talking about a stock rebuild but rather a trans with hard parts, custom converter, and custom valve body. Goerend builds amazing transmissions for dodges. With an Auto you only have to get the turbo spooled once unlike an manual where every time you shift you got to get the turbo spooled again. Yes it cost more but once its built right you won't have to do it again. especially if you buy a transmission from Goerend. He offers a LIFETIME warranty on his transmissions.
