AOD Casting numbers January 04, 2008, 10:27:15 PM first, i got an 87 sport coupe with the 302 and the stock AOD. It had already had been rebuilt before i got the car and about a year ago my transmission cooler fittings dumped all my fluid and i still had to drive it home. it burned it up good but i put an after market one to band aid it for a while and it worked but now as you could guess its done for. i got a guy at work that bought a 302 that came with a AOD and he wants to put a C (3-4 i cant remember) so he wasn't using it so i bought it off of him. i noticed it was stamped 54 on the bell housing and the tail shaft needs to be swapped out, also the manual shift lever is turned down where mine is up. but i can fix all that but i got a question. once i got mine out i noticed that everything looked the same (aside mentioned above) but the stock one from my car is stamped 31x where the one i bought has 54. I've seen in other swaps people using the 54 stamped AOD for their applications so i was figuring that the 31x was stamped b/c in it's stock configuration it has the shorter tail housing with the electronic (digital) speedo. but i was wondering if theres anything else I'd need to look for? i mean i know an AOD is an AOD is an AOD (as long as its not an AODE, so I'm not too worried, but just thought I'd ask you guys...also anyone know how much trans fluid and the recomended type to use? i misplaced my owners manual (put it up TOO GOOD) Quote Selected

AOD Casting numbers Reply #2 – January 05, 2008, 05:44:36 AM Don't know about the numbers,but the the one you want to get was set up for a floor shifter "lever down",can be flipped.The fluid any name brand merc 5 fluid will due.I think it's somewhere around 8 qts. to fill. Quote Selected
AOD Casting numbers Reply #3 – January 05, 2008, 07:03:07 AM 12 quarts Dexron/Mercon fluid. Type V fluid is designed for Ford transmissions built after 2000 or thereabouts. Quote Selected
AOD Casting numbers Reply #4 – January 05, 2008, 09:28:38 AM Large cast numbers on the transmission case generally mean nothing... AFIK it's a number in the casting mold to identify it... Don't think I've seen two with the same number...BUT if the tail housing is too long, the shaft is longer as well... Likely it's from a Lincoln Mark VII, those have the down pointing lever for the floor shifter and are longer than Bird/Mustang unit... Quote Selected
AOD Casting numbers Reply #5 – January 08, 2008, 12:14:27 PM Yeah, the numbers on the bell housing designate what mold it came out of. Use Mercon V in it, because that is what replaced Dexron III/Mercon. Its not licensed anymore, so you will probably have a hard time finding some leftover. Mercon V is backwards compatible in the older transmissions, but not the older fluid in the newer transmissions. Also, make sure you flush your cooler and lines really well, otherwise the old nasty stuff from your blown up trans will get into the new one and burn it up too, probably the reason your first replacement blew.

Anybody ever heard of such a thing? Quote Selected
AOD Casting numbers Reply #7 – January 08, 2008, 01:04:27 PM i've heard even crazier things from people who hang on every word someone on the interweb says. The only thing that i've seen different is the tailshaft.. thats it. an AOD is an AOD is an AOD as long as its not AODE. even when i opened it up to fix the manual shift lever the internals were exactly the same (i ran out of time and my dad finished it up for me since im using his garage)btw thanks to slowfoxbird for the heads up, i forgot to do that (havnt ran it at all since the driveshaft has to be shortened, the splines on the new tailshaft isnt deep enough for my stock yoke, so instead of taking the hog out and fixing it and im not ganna alter the yoke either so im just ganna shorten the driveshaft, its cheap.)

AOD Casting numbers Reply #8 – January 08, 2008, 03:46:55 PM i JUST opened the box of ATF my dad got me and this is what i haveValvoline DEX/MERCFine print: "For vehicles requiring Dexron-III/Mercron"Would this be better or just as good as mercron v? (dont ask where he found it unless i go over there tonight to measure the driveshaft and pick it up to go have it shortened, actually i think i might do that) it came in a brown box without any names on it.

Anybody ever heard of such a thing?He's FOS... The Stang tranny is a bit better than the Bird unit even if it is only mostly valve body calibration... The Stang also has a larger O/D servo("B" vs "C")... AFIK, only bands in the transmission are for reverse and O/D... Other forward gears are by clutch engagement, amount of clutches can vary by engine application...Best transmissions would be the ones from the Super Coupes and Pickups(but AFAIK the P/U tranny is longer like the LSC version)... The SC tranny has a bit better calibration in the valve body and the large "A" O/D servo... The P/U has "A" servo plus larger (2" vs 1.5") O/D band... Quote Selected

[COLOR="Red"]DO NOT PUT MERCON-V IN AN AOD!![/COLOR]Yeah, do like me and use "F"... Hey it's been in there since '99(changed a few times), still goin'...Ran "F" in the sick AODE in the Grand Marquis for 98Kmi(from 33K to 131K, over nine years) when it finally started losing line pressure and would drop out of gear idling(Yeah wife about finished it off at the power puff drags)... Front seal is still tight, but it's leaking around the outside of the pump... Pump housing gasket may have fixed that, but would have still had the 1-2 shift issue, so it's outta there... Interestingly the pan is clean on that transmission...Yeah I put DextronIII/Mercron in the new one... Quote Selected
AOD Casting numbers Reply #13 – January 09, 2008, 09:04:30 AM All OD bands in AODs were the same, 1.5", the only difference is the apply servo. 1, 2, and 3, are clutch packs, OD and Rev are bands. Jim, that Mustang guy must have been thinking about the SuperCoupe trans, and thought that all 'Bird trans were the same... For sure you want the "A" servo if you can find one, or just get an aftermarket servo and pop in there, and it will have even more holding power than the A servo. I have never heard of or seen bigger bands in trucks,but then again, AODs are a little old to be coming in anyway. They do usually have the longer tailshafts like the Lincolns do. V8Demon, who told you not to use Merc V in an AOD, that is what is replacing the old stuff because it is backwards compatible with the older transmissions. Won't hurt it at all. We can't even get Motorcraft DexIII/Merc anymore, it all supercedes to the Merc V. Quote Selected
AOD Casting numbers Reply #14 – January 09, 2008, 03:32:11 PM I agree with slowfox,I went to my trans guy he says the same thing "back compatible",seen the lables on the drums.Merc 5's a bit more slippery than the old,Witch I'm not sure if thats good or bad!.I've been runnin it in mine.
