Lex - Thanks for the input and I carefully considered what you say, and reading up on the Supra forums the Auto TT is not all that and you are right to some degree.....However it is a step up from the SC400 stock tranny...right?
I think the stock SC400 built tranny will still lack the improved shifting and gearing that is in the Supra TT tranny...Again stock those TT supra trannies do mid 4 second range 0-60mph with just under 300whp or so...How bad can that be at stock? With 400whp I think you may achieve the high 3's or low 4's possibly with a good traction setup...Boost logic trannies get good and bad reviews.... HP holding capacity is increased but everthing else remains the same pretty much.....People are dumping those boost logic built tranny's alot. Ryan (sc400tt) says he dumped his and didn't like the feel at all...One other guy said the same...Supra TT auto trannies are smoother and perform pretty well at stock...Not all that but an upgrade for under $1000 hopefully...Got it down to $800 cash now...Trying for $600 cash and making this guy sweat. He has no bits as this tranny has been sitting dry around his yard for over 2 years now..The crashed car has 73,000 miles.........
I just think Toyota made that tranny to support 300whp and not 200whp (like our SC400's) so it has to be better.....I just want to know if it will take well to the Sc400...Not much info to go off of when pertaining to this proposed tranny swap...
WD - Independant transmission codes is what I read...Longer first gear, more clutch plates, swap is doable and easy from what has been said...Hope it is all true as I am about to find out....
