wondering what would be a good choice for an auto trans that will be farily easy to put in my 88TA. Has to be handle quite a bit of power. I KNOW my T-5 wont last more than a minute or two once i get the new engien put in, and a friend of mine keeps saying he wants my engine/tranny setup i currently have for his camaro. I know NOTHING about auto trans AT ALL!!! i have switch a few cars form auto to manual, but never from manual to auto. only trans ive heard much about at all is a TH400, any good?


in case you've seen any of my other posts, my build has taken a bit of a turn, i guess my girlfriend really like my TA so instead of making it a tin can, i will be pretty much doing the opposite, redoing the entire interior, fiberglass door panels, black everything. yadda yadda

 

how much power? what's the purpose of this car? motor specs? cam specs?

need overdrive for highway use?

 

I ran a T-5 for 3 years behind a 12 second LT4 with a Centerforce Dual Friction clutch doing 3k+ rpm clutch dumps. so before you go on about KNOWING it won't last, give us some specs on the engine you plan to install and that will help give you a reccommendation. I HIGHLY doubt you'll need a TH400.

 

350 bored .030 over, forged 383 crank, forged rods, forged pistons, 224/224 114LSA cam, Weiand Team G intake, Demon 850 blow thru carb, double hump or vortec heads (havent decided yet) twin T70 turbos, twin A/W intercoolers, MSD 6BTM ignition

 

You could run a th350 for 500hp + if you build it right, and you can get them built pretty dam cheap.

Thiers a guy around here who will build it to handle 500hp, for $400

 

gonna need it to handle a little more than that, the engine naturaly aspirated would be close to that

 

Well first of all, i would opt for the vortecs(ported of course) and a built th400 for your application, and by the way, select a blower cam for your application also, they will have on to fit your requirements.

 

Mike's Transmission. The TH400 I'm running came from a car that had a blown BBC putting out around 1000 hp. It was built by these guys.

 

Honestly i would like to have a manual transmission i just dont know what type of trans would be good. How much can a stock T56 handle?

 

turbomustangs.com

read it and read it and read it

you know a blow thru 750 type carb is good for 1100 hp right? Furthermore, check that site out and realize that cam is a poor choice for a blower, get a split duration for your heads. a twin turbo 383 is a nice choice, but it seems like you need to research it a bit more before proceeding, if you have the cash for twin turbo and a T56 then run aluminum heads and good luck.

 

450ish hp. do a G-Force upgrade and its "rated" to 900hp and 900 ft-lbs


and I take back what I said in my first post, TH400 with a manual valve body would get you your "manual" transmission if you wanted to go that route, or check into the G-Force kit. its not cheap, but worth it if you want to keep a manual trans.

 

OK, also i htought i remembered hearing that there are a couple different size TH400, like a short one and a longer one from a full size car. which would be used?
