On the way to school today my tranny decided to take a poop. But any way what Im wanting to know is what kinds of transmissions has everyone had luck with. I have a 2003 F250 and it has the 7.3. It has a garett 38r turbo, air intake, dp tuner. Im wanting to get a built tranny and I will probably end up getting injectors in the near future. It will be pushing over 400 hp. Any suggestions will be greatly appreciated.
