Well now comes the hardest part, whose trans to go with? I know I will get the BTS and John Wood answers after all the reading I have done. And it's hard not to go with one of those 2 after all the reading LOL. Just hard to make a decision when dropping that much coin and none of them are local, so you either install it yourself or spend some more coin to have it installed. Also the cost of shipping and fluid on top of it and being so far away if something did happen. Only know of a couple local builders, besides your everyday trans shop. One is Janis transmission, but not known for diesels, mainly for race cars. The other is Redline Diesel Power, but they're mostly known for the Cummins. Only one I have any personal experience with is John Wood, my brother went with his when his let go. Damn life decisions LOL.
