Hey all, just joined here to see if I can get some help with my mustang!

The deal is I have a 1994 Mustang GT with the 5.0L and AODE transmission. Recently, it stopped going into forward and now only goes into reverse. Now my options seem to me are to:

1) Send it off to be rebuilt (probably will cost $$$)
2) Find a junkyard one
-Only problem is there isn't a tranny behind a 5.0 at any yard near me, so I was thinking about hooking up one behind the 3.8L instead (not sure about if it will last)
3) Or my third option after doing some research was to find a 4R70W tranny from either a F150 or any other Ford car/truck that was sitting behind a 5.0

Obviously, if possible, I'd like to do the third option, but still unsure whether electronically it will work or if it will even hookup (I'm assuming yes since it is the same engine)

Any thoughts?

Rebuild your existing tranny with performance clutches/steels, 4R70W gearset, mechanical diode one-way intermediate clutch, and a performance valve body. Then top it off with a higher stall rpm converter, external tranny cooler, and tranny temp. gauge.

Do you need to do anything to the computer to swap the gearsets?

Well that sounds all dandy, but that seems like the most expensive route. I'm looking for the least expensive if possible... just need it to run and drive, not doing any racing or performance type events

Unless you can find a used one, just getting it rebuilt is the "cheapest" option.

When I got mine done, I also got a slightly higher stall put in it (2500 I believe. Isn't stock 2200?) a shift kit, new cooler lines and the rebuild.

Cost a little over $1300 all said and done.

Well, that is why I am asking if its possible to get a 4R70W trans from a 5.0 F150 and hook it up just fine since they are more abundant around here and only cost ~$300. Is there anything else I would need to make this possible?

My other option is getting a AODE from a 95 Mustang that was behind a 3.8. I just wasn't sure if there were any differences between the 5.0 and the 3.8 AODEs

Yeah it's possible. You could get a 4R70W from a 2WD 5.0 F150 or 2WD 5.0 Explorer, preferably '94-'95 so it'll be a straight swap.

The 3.8 AODE has fewer clutches so it won't hold the same HP as the 5.0 version.

Send Dan Silverfoxbody a PM and ask him, he sent me a built 4r70w valve body to put in my aode transmission, along with some other parts to make it hold up to 1000 HP

So it is a straight swap? There is one very close out of a 1994 F150 5.0 that I can pick up... Think I might go ahead and do that. Any other last minute chimes before I get myself into something that I don't want to?

Still waiting on my mechanic... In the meantime, will the valve body from the AODE fit in the 4R70W and work correctly? It had a shift kit put in a while ago, just wanted to check and see if I can easily transfer that.

My shift kit is made for the AODE and the 4r70w I'm pretty sure.

Should be a direct swap as long as the donor tranny is from the same year so that the wiring connectors are the same.

Ran into some issues...

According to my mechanic, the shifting mechanism is different on the truck than on the Mustang, and there seems to be an issue with the speedometer gear (can't remember the exact issue). Can anyone shed some light on this issue? I'm hoping these two things aren't problematic and can be resolved shortly! Thanks!

Speedometer gear shouldn't be a problem. Just count the number of drivegear teeth there are on the tailshaft of the new tranny and let us know. If you also tell us which axle gears and tire size you have, we can recommend the correct speedo gear.

Currently don't have the tranny in front of me, but wouldn't all trannys out of a 94 F150 have the same number of teeth? As for axle gears and tire size, as far as I know it's all stock, the wheels are 17".

Speedometer gear isn't that big of a deal either way, but the shifting mechanism is. Any idea on how to get around that easily?

I honestly didn't expect the shifting mechanism to be different from the Mustang AODE. How exactly does it differ?
