no, that's engine on, running, in park, and hot. (PAINFULLY HOT most of the time)

Does anybody know if a trans from a 90 or 93 3.8L tbird will fit in my 88? I found them at the local JY and would like to swap tomorrow but I am concerned about wiring issues and driveshaft length. (they told me last week they had 2 or 3 AODs from a fox mustang, but I went back today, and they had jack) GRRRRR

If it won't fit, I am considering simply switching the torque converters out, b/c I think my whole problem is that its not pumping fluid correctly.

Not sure about the 90,but the 93 is probably a AODE, that won't work. as a direct swap.

, you're right. I just looked it up, AODE's came into play in 91.

Thats why it looked wierd to me......

Do you think I would be able to swap torque converters between them though? I think I would like to go that cheaper route if possible.

I would reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeally like to get this done this weekend if I can, cause I don't know how much longer my current one is going to last. Its getting worse by the day.

I did a parts search, there may be a spline difference between the aod and e. 35 spline verses 31 for the E. but size wise everything else is the same. I know this won't help you now, but I may have a stock one at work yet you can have for shipping.

If your transmission is slipping at all, I would park the car right then and there and then either get it checked out or do a filter/fluid change. Especially if the fluid is so dark.

That could also be a really bad idea. A lot of the time, when the fluid hasn't been changed in a very long time and it gets real dark (almost oil like) changing the fluid could mean bye-bye for the tranny, usually within a day or two from the change. I'm not saying this will happen in all cases, I've just seen it happen way too may times. Just happened to my brothers car. He had real nasty looking tranny fluid, so he changed the fluid and filter, and his trans started slipping, then finally gave completely.

K thats fine, b/c they have a 1990 there which was right before the switch to E's. As long as everything is the same size wise like you're saying, then I will be 98% for sure be attempting a full swap out next weekend.(ran out of funding{and time}this week)

Thanks for finding that out for me.

What do you mean? Stock tranny, or torque converter?

Its getting so bad now, that I can smell tranny fluid burning after I park the car. And its not coming off my exhaust pipes either. It smells like old, worn out, fried tranny fluid. And I noticed today that when I tried to check the fluid again, the fluid was so hot that it was as thin as water. I mean, it wouldn't even stick to the dipstick, which was itself so hot I couldn't even hold onto the handle! I could barely see it on there, but when I wiped it off, it came off a solid black, and I just changed it [3] days ago. Ugggh.

Yeah, I've heard of that many times. I know guys who change tranny fluid as soon as they get their car, and then will never change it again, until bad things start going wrong on their own. I was scared to change it when I did.

Oh, and btw, just to make sure this isn't due entirely to a strong case of my own stupidity, there's nothing wrong with running this fluid in an AOD right? It calls for Mercon, but this stuff is [both?]

Check the fluid level without starting it and after the car has been off for a while. Compare that to the running fluid level.

Did it go down? If not, then you have a massive block or your pump is hosed. Check the cooler lines to make sure that they are free of kinks.

PS, the TC doesn't do the pumping, there is a pump right behind the TC that is driven by a couple notches on the TC housing.

Also, I replaced just the TC band on my SC trans a while back. Link here:

I'ts kinda a PITA, but when I got in there the OD band just fell out it was so worn. Replaced it and it ran like a champ.

Not everything got AODEs inn 91. They started in the big 4drs (Towncars). TBirds had AODs until 92. Mustangs till 93 I believe. I don't recall when the F150 switched over. Make sure you get an 87 or later trans as they fixed an oiling issue in 87.

Also, if OD is out make sure you are driving In D not OD. When it shifts to OD, you are slipping the band against the intermediate clutch housing and it will burn, burn like a wicker cabinet. I drove my SC for a long time in just D until i finally got around to fixing the OD band. Just pretend its a C4.

You have to understand the basics of Automatic Transmissions to understand this one. At the factory, Ford adds a measured amount of black magic. As the trans goes down the road, the black magic rubs off into the sludge on the bottom of the pan. The only way to replenish it is to take a sacrificial bath in ATF. Failing this, there is no known cure.

K thx, i'll def check that out tomorrow.

I typically drive in D all the time unlesss i get over 55 for a good while but its not so much that OD band is out, as it is just that the ol girl dont know its time to upshift. It'll shift just fine (in evey gear) when its cool.

My mind is officially boggled.

Sounds like you have VB problems. Most likely the seals have gotten very hard. When I pulled the accumulators on my 92, the seals were rock hard. I replaced them and the crispness came back.

I would look for a good used trans out of a running car.
Gluck.

Ha ha. I drove it home today, let it cool of for approx. 30 mins.
Went out, pulled the stick, wiped it, stuck it back in,(go ahead and have as much fun with that sentence as ya'll would like...) and checked it:

Yep, same place as when it was running.

Up past the line on the backside.

A torque converter ain't your problem, apparently it has seal or valve body problems which have fried the clutches... At any rate, if the fluid had risen 6" on the stick, it's been frying hot and is at death's door...

Any COLUMN shift AOD from another Bird/Coug 5.0/3.8 is as direct swap as is the AOD from a Grand Marquis or Crown Vic(through '91)... The floor shifter trannys use a different shift lever(could be swapped from your old tranny, have to pull pan and I believe the valve body)... The pickup and Lincoln MK-VII AODs are approx one inch longer, don't want one of those... Forget the AODE as well(converters DO NOT interchange), it is shifted by the EEC, ones from a 4.6 won't bolt up anyway...

The shift lever can be dropped by pulling the valve body (I think, been about 4 years) and simply re-installing it. Easy to do. I swapped a 87 v-6 into a 87 v-8 and had to swap it.

This is exactly the information I was looking for! Thanks.

If everything goes right, I'm about two days from buying a 96 Tbird and parking the Cougar. So I'll have some time to work on it now, and plus I know what I need so I'll have some time to get all the right stuff and get it done right the first time.

I appreciate everybody's help.

Also, thanks mods for moving the thread
