I have a 1992 Lincoln Town Car I don't know if it has an aod transmission or an aode transmission

it has to fit,sure.
and have correct gear ratios
4r70w this is only series number, not any actual transmission #
the TCM (part of PCM) must like it, for sure ratios.

the old box has tag on the side, and is bingo for full and real p/n#

any ford 85-95 auto from the 5.0 v8 will work for you, hope this helps. Ford AOD 4 speed auto.

if not wrong you have an AOD or AODE

they call that trans an AOD

IF IT WAS ME I WOULD PUT SAME YEAR TRANSMISSION BACK IN CAR.THE EARLY 90S YOU HAD AOD - E TRANSMISSION.

Several variations of the 5.0l V8 for the Lincoln 1987 Mark VII. 150 hp (112 kW), (112 kW) 270 ft-lbf SEFI (1986-1987) w/ AOD 4 Speed Automatic.
200 hp (149 kW) SEFI 285 (ft lbs)(1986-1987 LSC) w/ AOD 4 Speed Automatic
225 hp (168 kW) 300 lbf.ft (407 Nm) SEFI (1988 - 1992 ALL) w/ AOD 4 Speed Automatic
Thank you for using Fixya and hope this helps you.

There is only 1 transmission for a 1994 Licln Town Car. Its a AODE, Automatic Overdrive Electronic trans. Earlier trans were AOD, non electric. Before that it was a C-6. After the AODE, your transmission, was a 4R70 trans. The trans will need to be rebuilt or replaced with a salvage yard unit if its slipping, or making noises. If you have it rebuilt, make sure you get at least a 3yr/50k warranty. Most salvage yard trans will make it 12m/12k, so if the rebuilder is confident about his or there rebuild, he should give you that. The original one lasted how long? 1-800-950-4644 ext 203, Jeremy can help you. Rockauto.com for just parts. Hope this helps you.

According to Haynes Auto Repair Manual, section on automatic transmissions, the 1994 Towncar has the AODE transmission
Baumann Electronic Controls website
URL: http://www.becontrols.com/tech/ch1alphabet.htm
has following:
The Automatic Overdrive (AOD) transmission was introduced in 1980 as Ford's first four-speed automatic overdrive transmission.
The AOD-E transmission is essentially a beefed-up electronically-controlled version of the AOD.
If this doesn't answer your question, you might troll around the website.

the model of the trans is "AOD"

Low planerty gears, not a problem.
