When I rebuilt my 68 mustang, I used a 351 from an 1987 LTD Crown Vic. I kept the C4 tranny and now I am looking to put in an AOD.
I have the opportunity to get an AOD from a 1990 Mercury Grand marquis. Is this a doable swap? Is the bell housing for this tranny removable?
I know I am looking between 1987 and 1993, what other donor trannies are available? What trannie provides the best/easiest swap for this move?

Thanks in advance...

The AOD bellhousing is integral to the case, not removable....

But a 351 W block has the same bolt pattern as the 302, should match right up. And the AOD should be strong enought if you haven't breathed on it too much. If you need to make it stronger check performanceautomatic.com, they have AOD kits.....

AOD should make it very drivable, the 0.667 final lets you cruise easy, or instead bump the rear ratio for more jump off the line....

If, in the event the AOD from the 90 Grand marquis doesn't work out, what other vehicals are good AOD donors for my set up?

I forget what year they converted the AOD to electronic controls -- '96 maybe?

Before that they were basically all the same, so about anything that took a 5.0L should work, Lincolns, Tbirds, pickup trucks, Vics, Marquis.....

There were some minor differences in shift calibration but I doubt you would ever notice...............

Lots of AOD info

Here's a bunch of detailed info on AOD's, AOD/E's and 4R70W's -

This should give you all the info you want.

I rearead your post and noticed you're
swapping into a 68 - that should be a
great improvement!

I've got a 70 that I'm also hoping to
fix up like that, with a later efi engine and an auto OD trans. I currently have an
89 Lincoln Mk VII LSC that came with an AOD. I've beefed that trans up quite a bit and added an Art Carr mild stall lockup converter, which was a great improvement because stock AOD converters are quite low stall speed.

Here's some info on the AOD trans type swap into older Mustangs - by the way, all AOD type trans have the same basic exterior dimensions, incl AOD/E's and 4R70W's, although the mod motor tranny's won't bolt to a Windsor block.

In the article I linked to in the last post, it shows where some of them have longer tailshaft housings by about 1".

Let us know how you make out, it will likely be next year before I can do mine.

If I remember right, that Mustang Steve site has info on swapping an AOD into earlier Mustangs.

Also, send me your email, I've got a little write-up on the swap from info I've gathered together.
