Change to a different trans
ok, third time is a charm...this is the third E4OD I have torn up with my motor and I want to try something different.
Right now I have:
351W -> E4OD -> Borg Warner 1356 x-fer case -> 3.55 rear end
I want to change to a 4r70w but not sure what transfer case will work or what other adjustments will be needed (drive shafts)?

What are you hurting?
I know places like Lentech can build a pretty stout AOD that the mustang guys would use. A friend runs one behind a 427ci Windsor in a 75 F100.
I would think the E4OD would be worlds better and stronger overall. Just too big for a car.

You'll need a computer to make it shift. There are aftermarket computers that will work with a 4R70W.

A 427ci windsor in an F100 (assuming it has the biggest carb possible) is probably putting out 420 or 450 HP if na. Those numbers are just a little less than what my motor produces now. Mustangs are built to handle the power so I have to think it is possible.

Yes, the Windsor made 500 hp at the flywheel n/a.
Agree, the weight of a 4x4 truck will likely not be good on a smaller transmission.
I just don't see why the E4Od won't survive? What is breaking? Are these all "used" transmissions? Or rebuilt to a specification to make them survive. There are guys with turned up PSD's that have no issue with them.

A guy locally I talked to convinced me he could build a strong enough E4OD like what would go behind a diesel but I am starting to lose faith in the ability for my E4OD to hold up since this is the 4th rebuild.

No you don't. Listen to Mark, he knows what he is talking about.

Here is the interface for the software I use to adjust my trans...do we still need to discuss this now?

For clarity have you actually had the exact same trans rebuilt 3 times or have you had 3 different transmissions in the truck? In either case converting to a later E4OD would be easier than swapping to a 4R70w as that would require a different PCM and wiring changes.

He wasn't talking about a tuning computer he was talking about a control computer(PCM), are you using a Ford PCM or something aftermarket?

See that sounds like an electronic control problem, the probability of having the exact same mechanical problem with 2 different transmissions is next to zero and that false neutral sounds an awful lot like something that would result if there is a problem with the MLPS sensor. We have been saying this here for years, these transmissions are 100% computer controlled and you have to make double sure you don't have any electronic control issues before going into the trans or you just may waste a whole ton of money fixing something that isn't broke. Now there are some known weak points with the early E4ODs but I don't know if they manifest themselves in that manner, an E4OD expert could advise you better.

1 month after I got the latest trans installed, I had a trans flush because I wanted to make sure the solenoid pack remained clean.
I really do understand what you mean about making sure all the electronics are sound, it is something I will triple check.
