Firepunk is hard to go wrong with.
I searched high and low far and wide and can't find anyone at all with anything bad to say about them, and they run a very successful race truck too. The guys who do that know what works and what breaks better than anyone.
Durb, I consider upgrading the 47re/48re absolutely mandatory. A better valvebody will increase the transmission's internal line pressure which makes the shifts firmer. Slippage = wear and inefficiency.
More pressure also makes the lockup clutch hold better. That is mandatory if you upgrade to an aftermarket "billet" torque converter, the stock pressure is inadequate.
Firepunk can set you up with a valvebody that will flow trans fluid while in Park. The stock trans doesn't! And not all valvebodies correct this.
The stock transmissions in the old Dodges have the potential to be extremely stout, but they're lacking in a few key areas as delivered by the factory.
Good info, they were high on my list because they have one of the better prices. I will give them a call next week.
