What if: Swapping a 5R110 or 6R140 behind a 7.3L PS

Well, here is my new "What if"....aka, can it be done, if so how question. :no:

First of all, is bell housing of the 5R110 or 6R140 identical to the 4R100? And if so, is there stand alone computer for the TorqShifts to talk to the 7.3L PS?

I looked at the ratio's of the 5 & 6 Speed autos. I like the deep 1st gear, deeper then the 4R100. Looking at the 5 speed, I like the idea of more gears before getting to 1:1 ratio. With the 6 speed, one could, in theory, swap a 3.73 axle ratio into the rear (2.50 final ratio) and still have a similar ratio as w/ a 3.55 & 4R100 (2.52 final ratio)

4R00
1-2.71
2-1.54
3-1.00
4-0.71

5R110
1-3.11
2-2.20
3-1.54
4-1.00
5-0.71

6R140 Ratios:
First - 3.97:1
Second - 2.32:1
Third - 1.52:1
Fourth - 1.15:1
Fifth - 0.86:1
Sixth - 0.67:1

I haven't really looked hard in swaping. I know that there are stand alone computers for the E4OD and the 4R100, but I don't know about the newer transmissions that came behind the 6.0, 6.4 & 6.7.

Thanks to anyone who replies! :thup: (Last topic I put up, no one replied to my battery question.....)
