I have an '04 f150, I have blown the transmission(4r70w) twice in it now and now I'm pursuing changing the transmission completely. What exactly is linked in the computer system between the engine and transmission? Would a new transmission controller allow me to change the transmission or would their be some disagreement in the computer system? Is their a new efi computer, pcm, for the new modular 5.4L. What other transmissions would bolt directly to my motor, what adapter plates are avaliable?

-don't factor in transfercase or the driveshafts fitting

 

A 4r100 out of a Superduty or Lightning will bolt up no problem. As for the computer part, I have noooo idea. My guess is that Mike Troyer could take care of it...

 

Find out if the superduty w/5.4L comes with a 5speed, that should tell you if that trans will bolt up and the computer will cooperate. I know there are groups of people who crack PCM's, do their own tunes, etc and I'm sure there is a forum for them @ the XCal's website. Definitely post over there and I'm sure someone will work something out for you.

 

I checked the ford site the new 07 can have the 5.4L with the torqshift 5 speed, would this work, any pcm work needed, where could I buy a built torqshift 5 speed ready to bolt up and go? thanks

 

I do not see that anywhere, I just checked.

 

you'll need the PCM that comes with the torque shift tranny and a 5.4 engine then have that tuned to your truck..

I thought you were talking about the F150 w/5speed. I doubt the PCM will run the instrument cluster in an F150, so keep that in mind.

 

why not just buy a c4?

 

Cause it won't bolt up. And it's his daily driver...I'm pretty sure he likes his overdrive...
