Ever wanted Overdrive?
how much for a Ramzilla4 that is rated at 800hp? 5230? for that kind of money I can buy a 4l80e, with a brake and convertor, that is rated at 1200 hp.....

as I said ealier, my trans buddy has build some 518's, and while they worked they were a boat load of money for what you got from one. and the 518 does not have a controller available, the 4l80e has several controllers available, a couple of them will plug right into my f.a.s.t. ecu. so another words, no toggles. the trans will still function electronically. what it came down to, in my situation, was that the 4l80e was a far better choice. my trans buddy wis willing to build me a 4l80, with all the tricks done to it, including the 300m input shaft, 36 element sprag/drum assembly, red clutches, a 5 disc billet/stainless lock up t/c from
http://www.tcsperformance.com/ for an old aquarium that I have no use for. if he were to build me the 518 i would have had to given him some additional cash, and i would have gotten an inferior transmision, according to him. for what it is worth, this guy has been in business for 20 plus years. and he is not just some trans shop out in the desert. he has been invloved with countless desert race teams. had his hands in on some Ford R&D a few years back, so i trust what he tells me.....not to mention he stands behind his work. if I ever bust this 4l80e that he is building for me, just pull it out and bring it back to him, no questions asked. no time/mileage limitations.
