Fit.. yes. But first of all are you sure you have an actual AOD? What is the trans code on the calibration decal on your truck?

I would hope that you know whether you have an AOD or not. The Grand Marquis info is incorrect. It's either an AOD or it's a 1994, it can't be both. 1993 was the last year for the AOD. A 1994 would have the AODE. Though based on the AOD, AODE's are electronically controlled and NOT a direct swap. For About $1000 you can buy the electronic controls from Baumann or somebody and adapt the AODE to work but I suspect that's not what you have in mind.

With so many people that use "AOD" as a short form to describe any automatic transmission with overdrive the question has to be asked I think.. just to be sure. And I forgot but Ford started using the 4.6L in these cars in '92 so I'm not sure a '94 would have the same trans bolt pattern even if it did have an AOD in it, I believe the very first 4.6 did use the old windsor bolt pattern but that was changed after only 1 or 2 years.

I have the "O" with a "D" inside it on my shift selector and no overdrive off button on the shifter and the bolt pattern on the pan matches the AOD. I talked to a guy at Aamco and he said it was an AODE but I'm not sure if that is true or not. I've been looking at '93/'94 trannys but I think any 87-93 would be easier to find and install. Any advice or things to look for on those years?

Yeah that sounds like the AOD, the trans code on the drivers door pillar would be T.

AODE was never used in trucks and it was only used in cars for a couple short years. But all kinds of people and companies routinely interchange the terms AODE and 4R70w.. the latter being the trans that was used in trucks. The AODE has a computer controlled electrical locking torque converter but is otherwise the same as an AOD, the 4R70w is 100% computer controlled. All 3 of these transmissions use the same case and oil pan so just looking at the pan doesn't tell you much. 4R70w trucks have the OD cancel button on the shifter and a standard looking gear indicator pattern, and the trans code is U.

The latest trans you can find will be the best in terms of build quality.. there were a lot of updates done over the years, and one from a truck is better than one from a car. The AOD did appear in trucks as late as 94 or 95 but it was rare, late 80s to early '90s it was much more common.

No, that's not correct.

The AODE was 100% computer controlled just like the 4R70W. The biggest difference between the AODE and the 4R70W is the gearset. The AODE used the AOD gearset with 2.84/1.55/1.0/0.67 ratios. The 4R70W 2.84/1.63/1.0/.70 ratios.

A little bump here for a second question, didn't want to start another thread. Would a 1991 f350 AOD bolt up to my f150? Thanks in advance

F350s never had an AOD from the factory. E4OD and C6.

The AOD and AODE gear set used 2.40/1.47/1.0/0.67 ratios.

The 4R70W gear set used 2.84/1.55/1.0/0.70 ratios.

I was thinking somewhere along those lines, the guy says it's an AOD but I don't want to drive all the way out there to find out it's not. I didn't think it'd be so hard to find an AOD in north California, I just need to find a tranny that will fit and sell the ole girl so I can try out an IDI lol
