I see a few TBs made for the 5at. Any ideas on which one is the best? I have been looking and looking for something as far as a simple electronic transmission controller with no luck. I am trying to find ways to not void the warranty, with no luck

no thoughts anyone?

JMO.. but if you mod anything on the tranny, you own the warranty

TBs? You mean valve body upgrades? What are you trying to accomplish?

And forget the warranty once you mess around with any of the internals...
