Agreed on the converter. Soooo much better fluid transfer efficiency compared to the stock unit, truck will feel completely different.
im looking for 500hp range in my 04 automatic, really want a built trans but prices are high i was wondering if ill be fine doing maybe tc, flexplate, valve body, and billet input shaft, then getting airdog II 165 and using a bully dog power pup that i got for a real cheap price, that should get me what like 450hp? id rather have a built trans cause of the upgraded clutches and steels and billet servos and all that, but they're all in the $4400 to $4800 range, thats high unless i get 6500 out of my dodge dakota im selling, owe 3k on it so 3500 would be mine and maybe some of my tax money? opinions please
