how much does your AOD take? Reply #15 – August 04, 2006, 03:19:06 AM TF 347, the flexplate is the same, you will need different bolts for the tranny and bellhousing, I bought a shifter but it was not really needed unless you want to be NHRA legal. I was bracket racing every weekend so I changed the shifter. The TCI AOD will only hold 450 hp cause it is still a lockup converter. When the AOD shifts into 3rd the "pencil shaft" that is the high and OD input shaft locks the torque converter to the input shaft eliminating slippage by the converter, sucks for performance great for gas milage. Now there are simple fixes to this, one option is a 1 piece input shaft that can be ordered from lentech and installed by your tranny guy. You will need a converter that is for your 1 piece input shaft as well, It will no longer lock up either. No problem if you want to put that power to the ground, cause you will not need a trunk full of clutches and bands for that wimpy stock AOD. What you need to make that performance motor work is a performance tranny, either way you will have to give up something (c4= No OD, AOD= Lightweight wallet) That is why I went with the C-4, I can buy 2 of those trannys for the price of 1 lentech, If i cared about gas milage the car would be a honda and I would be jaming to the latest techno track while thinking a fart pipe would be cool. Hell no, when I get cut I bleed american red, white and blue. Cars need brutal face distorting torque and nitrous, broken parts are sacrafices to the god of speed and you and I both are the priests of that religion. Quote Selected

I dont have a hardened imput shaft and havent had anybody around to help me get the trans down to see if thats the problem...Im not thinking that it is since the fluid is messed up....Are you saying your trans is STOCK! If you are Im headed to the s yard!:giggle: Yes my trans is a NEVER apart '89 Super Coupe AOD. I bought it with 40K, still had the factory cherry bomb rolling around in the pan. Only mods are a Trans Go shift kit and the hardened inner shaft I already mentioned. I doubt I'd trust one these days, as you're not likely to find a low milage unit. Its up to approx 75/80K and is still shifting decent, although not as hard as when I first installed the kit... I'll need to have it rebuilt before the 347 goes in. Quote Selected

The 1-2 acspoogeulator is still there. Quote Selected

No Juice... Had the B&M 2000 stall and street tires... Blotched the first run, only went 14.4(eased it out the hole with a 2.4 60ft). Next run with a fair 60ft(2.15) it snapped the inner on the 2-3 shift, should have gone a 13.8 or so(still went 14.74 with only two gears). Was running 19lb inj, stock 55mm M/A meter and a stock 5.0 stang exaust system. Quote Selected
how much does your AOD take? Reply #22 – August 07, 2006, 11:51:55 AM Oh..it was special! we got the trans down and the torque convertor was stuck in place, spining it made a sound like a skweeky belt, after a little tug of war with the tranny it came off with the 3rd imput shaft still inside it, with some chunkys, the 2nd shaft wobels inside the first, and 1st wobels inside the torque convertor and something is clanking around in there. the trans pan had some chunkys and was full of friction material, now the first time I took it down it was too (w/o the chunks;) )but the tranny guy said it wasent worn so I passed it off like it needed to break in or something, but I dont think it should have that much in the pan after so little use this time. Oh it was also suposed to have a hardened imput shaft too. So I guess no matter what trans i go with I need a new torque convertor anyways... QuoteI'll need to have it rebuilt before the 347 goes inOh yea... you have some new plans? I suggest you upgrade your tranny better than a rebuild:D And my car seems to be twisted so you might want some mighty sub frames too!:giggle: If I had it to do all over again I would have went with a stroked 351 or a world block, cuz right now I want to upgrade but I dont think I can push too much more hp. I love a good stroker motor it builds Rs quicker than shiznit! Quote Selected
help me pick a tranny... Reply #23 – August 07, 2006, 01:30:24 PM Okay after looking at trannys I have some questions..I dont see an AOD (besides a lentech) that holds more than 450hp so Im looking at C4s and C6s..what would be the pros/cons between these? Does the C6 hold more power? I saw most of the competition trannys were C6s..Auto/manual? Youd have to be quick to hit that 1st shift! Probly would want a shift light or something right?then... the forward or reverse shift patern? Is it just a preference or does it depend on your shifter?I need a torque convertor that shares the same bolt pattern as my AOD so I dont need a flywheel.26 or 31 spline? More is better? usually is....I Just want to make a good decision and be happy with the tranny I get.:D I watched some highway races this last saturday, some were lookin for the cougar to be fixed so Im in a hurry now! maybe Win some of my money back!

how much does your AOD take? Reply #25 – August 10, 2006, 04:34:35 PM well the first question would be, what kinda of gears are you running?If its a 3.73 or 4.11 it will be hard to hit, but that all depends on how fast you can shift. TC'shiznit it, al though alot slower, with a stick, or so I would imagine.You also gain hp to the ground if you can get a stick that will handle the power, but then you lose alot of consistancy. Now, you have the gas and clutch to worry about, but it would make it alot more fun to drive IMHO. but clutching in traffic will get to you sooner or later.Really its up to you. Quote Selected
how much does your AOD take? Reply #26 – August 10, 2006, 11:54:59 PM Tranny Woahs, This is the question that everyone on this post should ask themselves when they build too much hp for the "factory" parts. AOD is an awesome tranny, just expensive, an AODE is another alternative, I believe it is the same length, handles more torque and does not have the "pencil" 3-4 shaft. C-6, hello modifications and welder (the x-member, driveshaft, shifter), Tremec TKO (face it T-5 is worse than the AOD) bangin gears rocks, based on your rear gears(3.73-4.10) I would find the highest first gear available cause shifts come awefully fast when you have 500+ hp. You will most likely never need another tranny if you have a manual, but cluthes are another story. Go with AOD/AODE or a C-4 they are the most cost effective and least amount of time intensive. I believe the AODE takes a computer to run, does anyone know? Maybe it is like a 700R4 or 2004R and you just need a switch. BTW if your input shaft is not broken in 2 then I would say it is hardened. Just your hub on the torque converter is not. I would try another hardened input shaft and a non locking torque converter with furnace brazed fins and roller brarings (precision Industries, TCI, High end B&M) after I cleaned the tranny and see if the AOD still works before spending another dime. After I bought all of the right stuff for my AOD it was the clutches that let go and the case broke not the input shafts. I bet it was the input shaft and it still works fine. BTW do any fwd gears work? if 1&2 work it has got to be the shaft, your shaft was harder than your converter and destroyed (I love using that word) the front lockup hub inside the converter. If you have the tranny apart have your tranny guy install a 1 piece input shaft and buy a lentech or precision converter that will work. I hope this helps. Quote Selected
how much does your AOD take? Reply #27 – August 11, 2006, 10:34:33 AM My 1st and 2nd still worked but not as firm when I got the trans down the torque convertor was stuck in the tranny! We had to get it out by pushing it in and out with the help of a hammer!:shakehead The TC is junk it jingels and clunks not to mention that the input shaft is still stuck in there...:rolleyes: I couldnt find a clear answer for how to install a c4, so I took my AOD to my tranny guy and he said hes never seen that before!:eek: Anyways hes taking it apart to see if its still good, he said the material in the pan was probly from the torque convertor cuz he runs the same trans on 800hp cars and if everything is still fine on the inside Ill go with a one piece shaft and a non locking convertor.
