Ok I haven't had much luck from the mustang forums on whether or not this transmission will work. I figured if anyone would know it would be you guys. Anyway, I have a '96 Mustang GT with the automatic 4R70W. It slips pretty bad so I searched around on the net and found a guy with a 4R70W from a '93 Lincoln Mark VIII. He says it will work but I'm having trouble confirming this? I don't want to go through the trouble of installing new seals and putting it in the car if it's not going to do me any good. Here are pictures of it and the model numbers. Thanks for any help guys.

On the Tag:
PKE-D1
F4LP-AA
025595

Bellhousing:
32

Body of Transmission:
RF-F4AP-7006-AC

Tailshaft:
RF-F3LP-7A040-AA
Basic-4

Inside bellhousing plate:
G36
7A105-AA

If it really is from a Mark, then yes it will fit and it will work if you swap out the TCC solenoid. I guess a quick way to make sure it has the modular bellhousing is to see if it has 3 starter bolts. IIRC, the 5.0/3.8 bellhousing used 2 starter mounting bolts. Hope this helps!

Yeah, it will work if it's from a MK, but that is a serious step backwards for your car. Anything prior to 96 was so much of a pile of junk internally that they aren't worth their weight in scrap prices. I can't use them as cores because I have to throw most everything away. Starting with the case.

I wouldn't do it, but thats just the advice of someone who specializes in these transmissions ;)

Yes it has 3 starter bolts. Someone on the mustang forum also mentioned the 3 year gap in technology. I guess I'll just rebuild my tranny. Do you guys know of a good manual for rebuilding the 4R70W?

93 is a boat Anchor & not a very good one at that....

Guys will reccmmend the inexpensive ATSG but IMO if you have not rebuilt one before it's WAY too thin on detail so get a REAL Ford Manual off EBAY.

Secondly you can rebuild the 96 like I did here:

But in the end by the time you buy the hard parts needed to get a 96 right you might as well buy a used 98 or newer & Overhaul it - Good luck & the dude in next Thread is overhauling his now so...

I think that came from a 94 Mark VIII. The Mark VIII trannys are better than a stock 'Bird tranny because the roller clutch has more rollers. However, everyone is correct in telling you a newer tranny is even better than that because of the mechanical diode instead of the roller clutch.

Here's a list of tranny numbers I posted awhile back:

Where is that located? Do I just use the one from my stock tranny?

It has plenty of good uses, Boat anchor, weight for the back of a pickup truck and the best one of all.....scrap value

So will it get me by while I rebuild the tranny that came out of my car? Im wondering if it could be something simple with my stock tranny? It was slipping and had trouble switching gears sometimes. If it's a bad torque converter or solenoid that would be great. If that's the case I wouldn't even mess with the older 4r70w. I just figured I could still drive my car and rebuild the tranny at the same time if that's what it needs.

I prefer not to answer the "how long will it last" questions. It may last forever if you have a show car that doesn't get driven, it might not work when you put it in.
