PLS Recommend AOD Tranny for 67

93 was the last years for the AOD before the Aod-e came around. i'll have to double check but i'm pretty sure it was still used in the mustang in 93, the 94-up mustangs i know for sure used the E version.

I bought a Performance Automatic AOD with 2500 stall and it runs great in my 66 coupe. I have 3.55 posi out back and I cruise around ~2100 rpm at 60 mph. Good trans so far (and I even chirp second on command ). Good Luck

I thought the stall speed had to be below the cruise RPM, no?

You know, I've never really put the two together. I don't have a tach at the moment so I'm guessing at the exact RPMs at 60. But when in overdrive the motor is purrring along (unlike the C4 I had in it previously with a similar stall converter). I'll have to ask my buddy about that ( i did not buy the T/C myself, it came with the AOD from the performance shop, I'm taking the mechanics word). I guess I really just need to put a nice tach in the car (looking at one of 6-gauge replacements) and see whats going on. My car runs great since the new AOD install. I'll get back when I have precise cruise RPM measurements. Interesting..... Thanks

Got one today for $250. It's from a 91 Gran Marquis. They didn't have any from 5.0Mustang, Cougars or Thunderbirds

And I'm not so sure of the Hex indent in the top of the case. All the ones I seen with that mark were out of 4.6 motor cars.

That makes sense because my friend's 87' mustang with an AOD said his trans is giving him nothing but problems.

If interested....

I have a BUILT AOD. It will handle anything you throw at it. Just needs a Valve Body and converter. Zero miles on the trans since it was built. Just pm me if interested.

Can't go wrong with a Lentech.

I loved my Lenny!

Unless something goes wrong and you have to send it back to Canada. Then the taxes will kill you.

Well the $250 AOD i got from the junkyard was...well, junk. It wouldn't go into 3rd or OD.



I had a reputable transmission shop check it out and they said it was toast, but rebuildable. It didn't have the data tag, but also they were pretty sure it wasn't a '91 AOD.

They said it would be better to take it back to the salvage yard and try another. So I got one from a '89 Cougar this time and it has the data tag to verify that. And it does have the recessed hex casting mark in the case previously mentioned. I did another clean-up and paint and installed it.

I had to do the linkage swap so the shift lever was up instead of down and while I had it off I replaced the seals and modified the arm one inch longer to match the throw of the old C-4 shift lever. I got the new filter & gasket on and sealed the pan.

Tommorow I'll add the fluid, fire it up and check the TV pressure and give it a try. If this one has issues, I think I'll remove it and have the transmission shop rebuild it. They said $650-700 depending on what it needs.

Any pics of the "hex"? I have three AOD's sitting in the garage for various toys. I'd like to verify what they are. I know one is from an 89 Grand Marquis since I pulled the entire drivetrain and put the 5.0L in my Bronco II (another unfinished project )
