AOD issues April 08, 2010, 11:23:42 PM (Edit: This was originally an add on/reply to another thread, but I had the mods move this to its own thread. I felt like it deserved it. Thanks mods.)Similar situation here, if you guys could help me out, I would very much appreciate it. I have 88 v6 w/ AOD. Heres the story...: last wkend I was driving back home on the free way, doing about 75 and everythings going normal, when all of a sudden the car lurches and feels like the tranny swithced into 3rd gear for a second, then goes back to normal. It stays normal for the rest of the ride until I get off the ramp, and when I go to accelerate it feels reeeeeaal nasty. I dont know squat about transmissions, but what it felt like to me was that the *tourque converter was slipping???* kinda like it just didn't want to grab and complete the drivetrain. And it was having some trouble upshifting too, from 1-2 and 2-3. 3-4 was normal. I got it home, and checked the fluid, and fluid was waaaaaaaaaay to far up the stick. I wasn't sure if it was a bad reading, so I checked it again, and got same thing. It's been doing it for the last week, but since this car is my dd I had to drive it, I just been taking it easy. I finally got paid today, went and bought a siphon and pumped out all the extra fluid. I pumped out and entire HALF GALLON of extra fluid!!! I don't even know how that happened (I'm never taking the car to express lube again). I thought that would fix all, but when I went to test drive it today, it got worse! Now its doing what he said above. When I'm at a stop light or the like and give it gas, it doesnt matter how hard I hit the throttle, the same thing always happens: car gets up to about 5/6mph and lurches hard, and I lose all momentum, feels like its slipping into neutral, the rpms go up to about 25-2800 and it catches, happens again about 2-3 more times, and lurches back and forth every time, and then it shifts straight into 3rd all the way to upper 40mphs and shifts seamlessly into 4th, which is strange cause I always used to have a nice "ker-plunk" every time it went into OD. Sorry for being so long winded, I just want you guys to understand what I'm dealing with, cause I'm really worried. I had a similar situation happen before to another car(pos windstar)and that was quite an expensive repair job that I DO NOT have the money for right now. I am going to try a complete fluid/filter this wkend, cause the fluid is *dark brown/BLACK* and I am hoping that might fix it. If anyone has any idea what else might be wrong I would surely appreciate any help. Thxp.s. i took a video of the tach as this was happening; this is from stop at a red light and it looks like I gunned it but its only about 1/4 throttle at most. Its acting really crazy, was hard to keep the camera still cause of the lurchinghttp://www.youtube.com/watch?v=9bYliX1hBt0 Quote Selected
AOD issues Reply #1 – April 08, 2010, 11:54:41 PM The darker the fluid is, the worse shape the tranny is in, more likely then not. How is your TV cable/linkage? http://www.coolcats.net/tech/troubleshooting/shift.htmlIf your transmission is slipping at all, I would park the car right then and there and then either get it checked out or do a filter/fluid change. Especially if the fluid is so dark.If it is the TV valve, park the car. Do not drive it. a tow would be cheaper then replacing the transmission. When I bought my car, the stupid tv cable was already "fixed". Vacuum line with a zip tie. It is probably tighter then the replacement part, and it has been there for quite some time. Quote Selected
AOD issues Reply #2 – April 09, 2010, 12:11:29 AM Just to be certain you were checking the fluid with the car running and hot and it was reading way too high right ? The symptoms you describe sound pressure related , but also similar to low fluid Quote Selected
AOD issues Reply #3 – April 09, 2010, 12:15:32 AM what exactly is he talking about when he mentions bushing? I have a plastic clip-esque device on my tb mount that the tv cable runs through, but I dont think theres anything wrong with it....Pics: Quote Selected
AOD issues Reply #5 – April 09, 2010, 12:25:55 AM didn't see your post sorry, yes it was hot and running and I had fluid near 6" of the way up the stick *yeeeesh*. I siphon pumped it out to below the crosshatch (all the time scalding my hands on the 200 degree fluid), and filled er up to just below the top of the crosshatch area like it says, and voila: still runs like shiznit...

AOD issues Reply #6 – April 09, 2010, 12:28:43 AM I dont know the adjustment procedure for a V6 TV cable ....sorry Hopefully someone else will chime in Quote Selected
AOD issues Reply #7 – April 09, 2010, 12:38:59 AM i had read on cool cats about how the throttle cable to the pedal can stretch over time (which mine did), and i fixed that via secret shimming techniques, and how the tv cable is capable of the same thing. when I fixed my throttle cable i checked to the best of my knowledge to see if the tv cable seemed stretched to the trans, and popped it off the tb and gave it a few tugs by itself, it was very springy and I felt no play or looseness in the cable. I did check it again today and it still felt the same. But, that doesn't mean thats not the problem. I am definitely going to change out the fluid and filter on sat, or hell, i might even get to it tomorrow night, when I do my sway bar bushings. I'll make a night of it!:toilet:Btw, i forgot to mention that if I pull shifter down into 1st, it grabs just fine and stays there until i move it up, just like it should. Then when i go into D it shifts up to 2nd and to 3rd almost normally and i pop it into OD and goes into 4th just fine too. This to me makes me think its something to do with the kickdown but i'm no trans tech, so i guess i'll play with it if the fluid change doesn't help.Appreciate yall's input. Thx Quote Selected
AOD issues Reply #8 – April 10, 2010, 03:08:57 AM Hey good news for anyone paying attention! After the P.I.T.A. fluid/filter change, the car runs great!!! Between that and the sway bar links and bushings i replaced today, i couldnt be happier! Well, i guess i could be happier if it hadnt taken me to 2.30 in the morning to finish everything!

AOD issues Reply #9 – May 20, 2010, 11:11:24 PM well, its back to doing the same 'ol thing again, and actually it was just a couple days after this last post it went back to it. It wasn't as bad as before, but its been getting worse, and a few people I know and myself included are pretty much convinced the tq converter is going out, and I would like to get it fixed before its gone.I found this, http://ocala.craigslist.org/pts/1730337921.htmland am considering swapping the whole tranny over, but I'm thinking it probably wont fit. Otherwise, I go with this,http://orlando.craigslist.org/pts/1748035220.htmlbut I really don't have the cash to shell out for this one right now. (or really for the other one either for that matter)*Sighhhhhhhh* I'm starting to get mad at my car again...Any suggestions? Quote Selected
AOD issues Reply #10 – June 01, 2010, 05:00:25 PM well, its doing it again. The exact same thing. I changed the fluid and filter again today b/c I was reading an old thread about how to adjust the TV cable and also how not having a gasket between the pump and filter can cause problems b/c of it pumping air instead of fluid, and I didn't remember my last filter having a gasket.I changed it all out, lo and behold, no gasket between the filter and pump. Added 4.5 quarts of Merc, and let the engine heat up. Checked the fluid, and it was pretty good. Right were the pink arrow is pointing in the picture below.Went out for a test drive and it ran great for about 5-10 minutes. YAAAAAAYYYY. Thought I was good. But shortly after, it started acting exactly the same way. I checked the tv cable and tried adjusting it a few times, didn't help. It also will not shift into OD anymore. No matter where the TV cable is located. I went and checked the fluid level next, and guess where it was. Right where the green arrows are pointing. Which, is exactly where it was before I changed it the first time, and exactly where it wound up at after it started doing it again. I am SOOOOOOOO PISSED OFF at my trans.I don't know too much about transmissions, but my thoughts on the subject were that the torque converter/pump are going out on it, or I've got something stuck in the valvebody???Anyway, my solution is going to be switching in one of the $250 mustang aod's in the local JY. I should have no problems getting it to fit and work correctly right? Quote Selected
AOD issues Reply #11 – June 01, 2010, 08:49:55 PM Are you checking the fluid with the car in park?It'll read high in that case.... Quote Selected
AOD issues Reply #12 – June 01, 2010, 09:03:14 PM yes. car in park. just like the dipstick says. and the manual. and the haynes book. and you guys....why do you say it would read high? Quote Selected
AOD issues Reply #13 – June 02, 2010, 12:00:06 AM I'm betting its more the internals of the transmission that are the problem at this point. I had a buddy that had the same problem on a z24 cavilier, ended up being the TV cable fell off. I love car engineering. With a fluid and filter changer, it is much better when warm, but still slips alittle bit until then. His fluid was dark as anything and smelled like burnt piss. The darkness in the fluid is parts of the clutch burning up. Also, if you can, put a magnet in your tranny pan. I check mine in neutral? Quote Selected
AOD issues Reply #14 – June 02, 2010, 02:18:07 PM I meant in park and engine off. If I go out to my car& pop the hood with the car not being run for a while, my fluid will read right about where yours does in that picture. Quote Selected
