    I am about to remove the AOD transmission from a 1992 Grand Marquis to swap into my Comet. Other than the transmission itself, what else should I grab off the car that I will need for the swap - flex plate? torque converter? shift rod? wiring?

    Thanks

    You'll need the engine plate, and grab the plug off the backup light switch.

    Are you positive it a AOD & not AODE? The AOD was only used approx half year in the '92 before switching to the AODE(which won't bolt to a 5.0 as the bell configuration was altered with the trans change)... Yes there are two different bolt pattern 4.6, similar deal to five & six bolt 289...

    Not positive. I just assumed it was an AOD. Thanks for bringing that to my attention. Is there a quick way for me to tell the difference - should I just look at the bolt pattern?

    The AODE will not have a TV cable, is fully electronic... Also the AODE uses a three bolt starter vs the two of AOD... AOD saus Automatic Overdrive on the pan, I believe AODE mentions electronic...

    I owned a early '92 Grand Marquis with AOD and a '93 with AODE(basically same as late '92)so am familiar with those, G'luck...

    BTW if it is AOD you'll need a TV cable from a carbed or maybe CFI 3.8/5.0, one from the 4.6 isn't going to work...

    The AOD will only have one electrical connection, a 4 pin round connector for the reverse lights, and the neutral safety switch, and they also say "metric" on the pan.

    I definitely have an AOD transmission, thanks for all the help with identifying it.

    As I was working on removal today (separating the torque converter from the flexplate) I encountered some difficulties. I know that the four nuts attaching the two have to be removed, but as soon as I apply any force everything starts to rotate counter-clockwise.

    How do I get it to stay still in order to loosen the nuts? Also, any idea how to get a socket in there? I am trying to wrench it and keep things from turning with zero success.

    If I can't separate the torque converter, I can still get the transmission out right?

    I've had good luck with clamping a pair of vise grips to the flex plate when the starter is removed. That will stop the engine from turning. As far as a socket, you'd need a super short one with a small breaker bar. I usually use a box wrench. Make sure you have a " stepped " one so that it sits squarely on the nut and it's not tilted or you will strip the nut. :)

    Edit: if you have to, you can pull the trans out of the torque converter, but you'll make a huge mess! You'll also run the risk of bending the flex plate!

    Not a good idea to try to pull trans with torque converter still attached to flexplate, at the least you'll probably damage the front pump bushing...

    If it has the large round rubber plug on the driver side of the block(I know the 4.6 with AODE do), pull that out and rotate engine till a converter nut is visible... Use a ratchet or breaker bar with extension and socket to remove the nut, move on to next one...

    BTW I forgot to mention the converter will still likely "roll" just allow the socket to contact the edge of the opening, that will stop movement and nut should be fairly easy to remove...

    AODs don't have the rubber plug.
    Sometimes you can get a boxed end wrench on one of the nuts in the starter hole, and use that to hold it, or get a socket to fit on the bolt on the front of the crankshaft, and have someone hold it in place, just don't strip any of the nuts....

    You well may be right, I never had the trans out of the AOD car...

    The opening for AODE is in the block, not anything on trans it's self...

    Well a new day brought success. I was able to insert a small ratchet extension into a hole on the flexplate to stop things from turning. Using vise grips I was able to get hold of each of the nuts and turn them off. It was easy once I figured out a strategy.

    Getting all the bolts out of the bell housing was relatively easy with a series of extensions on my ratchet. Separating the transmission from the engine was a challenge but I eventually got it out. Some pictures of the AOD transmission and the donor car. Thanks again to everyone for their help.

    You'd have had a much easier time if you took that little tin plate off of the bottom! (y)
    Edit: By the way, what was wrong with the donor car? :)
