    Another bum transmission, what should I do?

    !Question! Just hoping to confirm an AOD is an AOD is an AOD. '86 Mark 7 tranny will work in our cars correct? ('91 grand marquis)

    I dropped everything off at the transmission shop earlier this week they dropped the pan, & the Mustang AOD I bought off of 1980c10 is probably bad. The guy showed me the pan and while the fluid is still reddish, there's DARK GREY goo coating the entire pan and he said he thinks that indicates torque converter issues.

    So now the car is in the shop and I have no transmission to put in it!

    The shop is pretty honest, they've been around forever, and I've had them put a tranny in an old Taurus I had years back. They're quoting between $1300-1500 for a rebuild with a shift kit and a one or two year warranty (which is probably a pretty good deal).

    Do I bite the bullet and have them completely rebuild the transmission and install it and then wait until I can afford to have exhaust made before I can even start the car? Or do I drive 65 miles away and pick up a boneyard trans out of an '86 Mark 7 for $300 & can afford to do the exhaust and be driving by the end of the week?

    Thoughts? Advice? Thanks!

    the dark grey for an AOD means clutches... The torque converter in those doesn't have clutches. They literally throw fluid from one side to the other (in a manner of speaking) to get things moving. Basic soft parts rebuild should only be about $800 total. If the bands or worse (other hard parts) need replacing... it goes up from there. Remind him that it's a non-electronic trans... aka... no lock-up torque converter... All the clutches are in the trans itself.

      Well the 13-1500 is for a full rebuild with shift kit & warranty, and I took them both trannies, the one Shawn (1980c10 said would shift into 3rd or 4th) they pulled that one partially apart in front of me (as the torque converter is out of it, & said it was definitely slipping and it isn't fixable cheaply because of the pitting on the metal bands/whatever.

      I have to let them know what I want to do on Monday, so definitely keep the suggestions coming.

        I believe the Lincoln AOD's are longer than the Ford/Merc.

        The problem with the junkyard trans is it could be in the same or worse shape than the one you have. What are they charging you to install the trans you have? Is it worth a gamble that it may last a while with new fluid.

          It's $350 for an install, and I'd think the 1300-1500 complete rebuild includes install. And it may be worth a gamble to put the trans I got that came out of 1980c10's purple Mustang, with new fluid. Some hard shifts, but didn't seem like it was slipping or anything when I rode in it.

            You have witnessed this tranny operating? Well, then IMHO I'd let them install it for the $350. After that, install your exhaust and then maybe start a small fund for the day it gives up.

              If you know it works and need the exhaust, go that way. The hard shift could have been a tight adjustment on the cable.

                Lincoln trans is longer. Doesn't fit a Mercury.

                I ran a trans in my car that had the pan totally coated in clutch material for a while. Shifted fine, no problems. If you know it worked, I'd stab it in there and save your dimes for when it eventually dies. It may be 100k miles though, or maybe it won't be.

                  +1.As the trans in my 84 has 240k and when i first got the car it had the same issue with the stuff in the pan and it hasn't given me to much grief yet. After a few flushes and some trans cleaner she is shifting smooth and is finally down shifting out of overdrive with more adjustments at the tv. My dad always said if it ain't broke don't touch it as I'm slowly learning this. But i don't drive my fords like a bat out of hell so I'm assuming this is why she keeps on going. If you feel that the trans out of the other car is good still than go with it but a new trans would be nice but its a wallet burner.

                    Yeah, mark 7 tranny is longer.
                    It is JUST the output shaft: if that's the only way to go, I can send you a short output shaft (and matching housing). You have to tear the trans down to swap the parts, but, you don't have to pull apart drums.

                    But you should be able to get a junkyard tranny for waaay less than $300. In my neighborhood, cores are like $75, even working ones; and $300 should get a fairly recently rebuilt one. We're talking craigslist. Mostly, mustang guys who have swapped to a manual, or put in a performance trans, etc., and want the old one the hell out of their backyard.

                    I actually still have my old transmission-- it was rebuilt 20,000 miles ago and is in great shape. I rebuilt another, to learn how, and put in a 2" overdrive band and shift kit
                    It's a 1990, so it has the E9 valve body and 4-hole output shaft (more lubrication for... the planetaries and direct drum? better ask alan @dirtydog or dan @silverfox to be sure). Anyway. More modern/better stuff than I think it was 1988 and prior.
                    We went through it all, had it completely apart, it's in great shape inside.
                    I'll sell it for $300. The overdrive band shows light browning, so it's trivial to replace it for $15 while the trans is apart. I'll do that for you. A $15 3-4 accumulator is an advisable upgrade. Dan @silverfox can do a good job with a valve body for you; I don't trust myself on that. The $100 one with modest improvements is working great for me, fwiw.

                      I'm not positive that clutch material in the pan, perfectly correlates to the condition inside.
                      I'd look to the fluid first: not whether it's dirty, but whether it's BURNT.

                      I'm new to the game,
                      but I've already seen many transmissions with fluid like engine oil that shifted fine before, and after, flushes.
                      I've seen my own transmissions with light dustings of clutch material in the bottom, and no problem.

                      And I saw a friend's transmission with a light dusting of clutch material, that slipped in 3rd and 4th-- because his tv cable fell off.
                      There was even less clutch material than other transmissions I've seen the pans off of, but, the fluid was definitely burnt, that was the real distinction. It smelled burnt, and side by side with a good trans, the fluid had lost color (more watermelon pink than cherry red) and gained opacity. You can tell a difference between good oil that has dirt suspended in it, and oil that is itself burnt.

                      Other issues won't be visible in the pan. The same friend then bought a craigslist "performance" trans that won't shift at all! Clean as a whistle 40 miles later, you'd suspect nothing from looking at the pan, nothing wrong with the install... something's f*cked up.
                      We tried putting his original valve body back in, no help there. Next we're going to look to the governor, and after that it'd be a tear down... maybe the guy who did the modifying left out a sealing ring or something.

                        $1300 is fair for an install with shift kit and warranty. Can it be cheaper? Yeah... but they're not ripping you off, no one's making a fortune on trans rebuilds I don't think.

                        Hard parts are unusual to go bad in these; mostly a stock clutch & seal rebuild should be OK. Everyone tells me that the planetaries last forever, and maybe sometimes the reverse drum clutch might go, or an inexpensive bushing here or there.
                        If you do need a hard part for the trans you have, I might have a spare for not too much $, and certainly alan or dan can hook you up. Even planetaries are $60 rebuilt from transtar industries/ transtec, or $30 used. These transmissions really are cheap cheap cheap.

                          A Lincoln trans won't fit unless you get a 2 door Lincoln Mark 6 driveshaft.

                            too high if its a stock rebuild without a 2 inch overdrive band and diode instead of a roller clutch. you might be better of having alan come get it and do the rebuild he also does converters as well. if your going to spend the dough might as well have him do it, hell ill even help with the rebuild and install if you do!

                              this just in from what alan told me the direct clutches are fried in the trans. i still think you might want to find out exactly what all they will put in your trans for 13-1500 find out and get me a list compare with alans pricing and parts and then go from there.
