T-5 to 4R70w swap

[andres2882]

So here's the deal, due to a motorcycle accident, I need to convert to an automatic setup that will allow me to drive one-handed. I have been researching all the different possibilities and have effectively decided on swapping in a 4R70w transmission from a 2003 3.8 Mustang into my 1992 GT and to use a Baumannator TCS in conjunction with it - mainly because I want to wire in the ManuTronic feature to use the cruise control as a paddle shifter. I guess I'd just like to run a few last questions by you guys first to settle myself.

1. In order to swap the new setup in, I need only the following: the 4R70 tranny, a 5.0 flexplate, the correct crossmember, and the TCS (as well as shortening my driveshaft and setting up a cooler system)?

2. My setup is for around 350-400 rwhp, will the aforementioned system work for me or would it be necessary to spring for the Baumann Valve Body Recalibration kit or an aftermarket torque convertor?

3. Is there anything I'm not considering that I should?


Thanks!

Sounds like you should be fine with that stock trans and the TCS. Get the converter with that trans also.
You will need the flex for the 5.0, yes.
SHorter driveline, probably, and you will need a 4R yoke or replace the 4R trans tail housing with AOD.
You will need to fab up another cross member from the AOD or whatever to fit, maybe even your T5 will work once fixed.
You will need to use a cooler, you are in FL, so a nice big aux unit should work just fine...try to get the first 12" or so of cooler line for the fittings.

that is a good start.
Sell your T5 stuff in bulk to make up for the price of the auto obviously.

Thanks for the info! Do you have any recommendations about the need to upgrade the stock components at all or should they suffice for my power needs in stock trim?

stock 98+4R would be great.
