Most likely your OD clutch pack is going, does it function fine in the other 3 gears? This happened to me once and i had to rebuild, in fact its sitting in my storage unit collecting dust if you want to just swap one in. PM for pricing.

What color is the fluid and does it smell burnt? Most likely its the overdrive clutches and will require a rebuild. Its too bad you dont live close to me. I'm a technician at an Aamco and I could have gotten you a deal.
OD band is fried. My 93 is the same way and I am just too lazy to fix it, plus it doesn't really get driven on the interstate but at around 70mph it is turning aroudn 4k rpm.
If you are going to keep the AOD then when the rebuild it then at a MINIMUM have an A+ overdrive servo put in. The AOD in Mustangs have a "B" servo and it doesn't have enough clamping force to keep the OD band from slipping especially at WOT. WOT on a stock AOD while in OD is a big
.
The best thing to do if you have the funds is to have the smaller OD band, I believe it is 1 1/2", replaced with the wider 2" AODE OD band. But this means replacing some other components in the trans which means more money.

Expect around a $1000 labor and around 200-300 in a soft parts rebuild, then they'll probably tack on 15% to 30%, then add on the sales tax. So I would expect to pay a total of between $1500 and $2000. I would guess it will be right at about $1700. If its a good Aamco they should have your car done within a couple days. It normally depends on how fast the builder is because the guys who yank transmissions can have it in an out in an hour.

This sounds good and all, but if you have Aamco or most any other main stream transmission shop install the better parts, it will void the warranty. Most transmission shops will only warranty a trans built to factory specs.
I hope you don't plan on having them rebuilt JUST the O/D band. If you're gonna pay to have 'em tear it apart, do it ALL, do it ONCE, and have 'em do it RIGHT.
Personally, I'd just hunt for a used AOD and either have a basic gearhead throw that in there, or do it yourself. Then buy a manual on tranny rebuilds/build-ups and practice rebuilding/beefing up the original on a bench while you drive around on the other in the meantime. Hunt the classifieds, eBay, Craigslist, etc. for a used tranny, probably can score one for $200 to $300. Might have to pay someone $300 at most to have 'em swap it out for ya'.

If he only wanted them to replace the overdrive they would void the warranty.
If I were going to keep an auto, I would get something stout like an Art Carr AOD and put it in. The stock rebuild you get from a shop will be nice and will shift like new, but it will really hold back the performance potential of the car.

Thats what he said he was gonna do. He said I mite not need a total rebuild. How much would something like this cost?
Thanks Daggar
True but the factory specs on an AOD in a Mustang suck. The OD band is extremely weak. And if he plans on doing anything performance related with the car he will more than likely end up with the same problem down the road.
Would it be possible for them to rebuild it to the T bird Super Coupe specs since they came from the factory with a "A" servo? If they can do that and keep the warranty then I would at least do that.
If you get another AOD to swap in get one from an 89 or later. They have better oiling features and some of the deficiencies of the earlier AODs were remedied. Also keep in mind that there are two different length AODs. I believe it was the Lincolns and the trucks got one that was a little longer and you would need to shorten your driveshaft. Just keep that in mind if you hunt down a used one.

Whether or not you can work out getting it built to T-bird specs is totally up to your negotiating skills.
