4R70W into ex-AOD Fox

[Ozz]

About halfway thru the swap and ran into some problems. I tried searching but this isn't exactly a common swap so I came up empty-handed.

I didn't get any instruction on what to do here and we have no clue. Hopefully I can find some insight here. I'd *like* to get some work done on this tomorrow (if not finish, ugh) but of course I can't talk to my builder until Monday. So:

1. The AOD I took out has the shifter lever pointed DOWN as mounted on the transmission; the new 4R has it pointed UP. The AOD has a stud & flats design for the shift cable and the 4R has a ball/socket type attachment. Did my builder mess up the pieces here, or am I supposed to do something I'm unaware of?

2. There's a 4-pin connector that came off of my AOD. My 4R has a sensor with 5 wires in it, for SS1, SS2, SS1/2 ground, TCC and I believe TCC ground. Now we have no instruction on which wires are supposed to go where ON MY CAR, nor have we been able to dig up a schematic to my 92 to figure out what each pin on the 4-pin connector is for. If we had that, we could figure out how to make the harnesses work with each other.

3. Should I need a Trans. Range Sensor or a connector for it?

4. Regarding the sensor on the speedo gear casing. On the stock AOD I have a sensor that plugs into a harness of the car. I believe it's for cruise control. It's piggybacked off of the setup that the speedo tooth gear slips onto before going into the transmission housing. On the 4R, there's a similar connector already in place elsewhere. Should I connect the harness from my car into the provision already on the 4R or should I piggyback it like it was in the first place? If not in the stock location, why the difference?

Thanks for any help!!

Isn't a 4R70W an electronically shifted trans? If it is I'm curious how you are going to control the shift points.

Dave, did you post on Clickclick?

I know you're after quick answers and you might have the best chance over there.
The Corral (as you know) has some good guys but they don't seem to always be around super often.

Good luck bud.

I MEANT to but for some reason, probably being burnt out from the day, I didn't. I did hit Corral and PM one of the guys I know on CCR directly though. I'll go there now. Thanks for the reminder

edit: just went over there and my partner in crime has already taken care of it

The guys at Baumann Electronic Controls can answer and and all questions you have about the 4R70W tranny. The one in my truck was acting like it was near death and a simple phone call to Baumann fixed it cheap.

Thanks for the link man - we've got it figured out though thankfully! We did it the hard way, but hey - that's how you learn a lot!

Here's an update for anyone who cares. I put it in my winter project thread and thought I'd copy it here. I KNOW there is no other info out there (if it is, it's insanely impossible to find) for a 4R70W swap into a Fox, so if this can sit in a search database for someone else to find it later, then great

Saturday was our intended install day. Sunday was a free day to finish up whatever we needed (in retrospect: lol). My builder and I agreed on whatever it took to make it a all-in-one install. Didn't end up that way by a longshot

The first problem was the harness plug on the 4R, no instructions as to wire what and to where. Couldn't reach the builder all weekend so it had to sit until we found (today) the pinout schematic for the stock plug. Those were for my neutral safety switch and backup lamps. Gotta have both of those! Also the gear lever was incorrect in both position and style. Had to overnight from Ford the proper 4R gear lever along with an MLPS which the builder didn't know I would've needed. Upon asking him about it it became obvious, but DAMN I wish that would've been taken care of or told to me in advance.

Anyway we let it sit Sunday because we had no news to work with, so the trans. cooler was installed and I degreased and cleaned the entire undercarriage and all the lower suspension and bottom end of the engine that I could reach. I was tempted to take my exhaust, some chassis parts and lower suspension stuff to the powdercoater while we were waiting to get back to the install, but surprisignly I was able to leave it alone and just get it real clean.

And finally today we bolted it all up to trial fit everything, and it was a success. The wiring is done, the harnesses are run, the blowby vac tube is installed, the cooler is finished, and all we need to do is rubber-plug the 4R, put in a new dipstick tube, and put on the MLPS and harness. Then of course the driveshaft and exhaust, say a prayer, and test it all out.

The parts on order will be here tomorrow and we should have it running by the early evening provided we don't run into any more stupid problems.

Let me tell ya, the 4R swap into a Fox body is not exactly easy. There are *NO* tech articles out there, the automatic gurus weren't sure of too much about it (it's a rare swap, so it's to be expected), and even my builder wasn't sure of a few things! That's a bad omen if I ever heard one, LOL. But I owe the success of it so far to my buddy who has been able to figure out all the wiring craziness, make the harnesses, and so on. He also figured out we'd need the MLPS before anyone said anything Without that I definitely wouldn't have gotten this far He's the one who lent me his lift for the rear disc job, as thanked in 50&SF. Gotta love friends with lifts!

This is going to be baaaaaaaaaad once it's all said and done
