i think my aod tranny is going out will a c6 or c5 work in it's place without cutting the driveshaft or changing the linkage in my tbird. i am going to change the filter and fluid today or tomorrow and see if it is working better.

 

The c6 will work but due to the size, you may have to modify the trans tunnel, you will have to modify or replace the crossmember and shorten the driveshaft. The c4 would physycally fit better, but again you would have to modify the crossmember or replace, and shorten the driveshaft. You might get the shifter to work but, if I were you, it would be a good time to stick a b&m shifter or something like that in there, going with the 3 speed. Might try and trade for another aod or go ahead and rebuild it, just a thought. Whats the tranny doing? Shortening a driveshaft shouldn't be terribly expensive, call a couple of shops, and see, if you want to put the c4 in it. Just a thought. Good luck, later

 

it won't shift sometimes unless you stomp on it and let off and it takes a couple of seconds to get to gear reverse or forward. i checked the fluid and it is brown and smelly but not too much burned smell.

 

try adjusting ur band, and a c6 is the same exat size as a aod so it will fit perfectly you might have to make a cross member for the tranny but you shouldnt have to change the driveshaft lenght mabe a new slide yoke is all depending on the year of the c6.

 

it is an 82 c6 it also shutters when shifting out of the passing gear. i changed the tranny filter and there was a 1 3/4 bolt in the pan. it was a bolt that held the valve body in i put it back in and put the tranny together but have not put the fluid in yet. i will in 1 hour or less.

 

I thought the c6 was the same dimensionally exept for the length. adilts2002, you may very well be right as I haven't physically compared the two. I did find this site

http://www.hotrodssuperstore.com/trandim.html

and it shows the c6 as being 3 1/2" longer than the aod, so modification to the crossmember and driveshaft might be needed. later

 

ok update on my aod prob. filled it up but actually overfilled it big time. i thought more came out than it actually did. went driving and it was working alright, then 10 minutes pass and this thing starts slipping like crazy. even when i put it in first it slips and sounds like it is in granny gear. will overfilling cause it to slip. i know it will bust my seals if i don't do something about it but i can't find a drain on this aod. so tomorrow i am going to unhook the return line and drain it that way until i get it at the right level. if it slips again after that, i am pulling the motor and tranny and starting my swap. i can't wait

 

wil a stall for a c4 work in a c5 since they are basically the same thing. how about a c4 shift kit

 

F100guy- a c5 is a c4 with an extra clutch pack or a very good shift kit. so i dont know why ur converters wouldnt interchange. did u try adjusting ur power band on ur tranny that will cause it to shift slow or slip. also how long did it sit dry? i had a tranny that sat dry for 3 months and it slipped alot. i said screw it and was tired of messing with it so i left it go and added somw luckis"spelling wrong" and after about 3 weeks it shifted fine.I also know if u dont have the TV cable adjusted right u can burn up a AOD tranny in about 5 miles.
jwtaylor- it depends on the year some of the older trucks had longer c6 trannys but some of the newer ones were a bit shorter i guess it all depend on the tail shaft on he c6 but i know that main tranny with no tail shaft, there the sam length as the aod.

you might contact these people

I have heard many good things about the company, and they should be able to help you more. I noticed that a c4 is usually listed as a non lock up converter and the c5 is listed as a lock up, doesn't mean they wouldn't interchange though. I found out that the c5 is an updated version of the c4 but internally there is nothing similar. Give those people a call and see what they say, later

How did you change the fluid if you didn't drop the pan? Fords don't have drain plugs on the pan, keep in mind there is one on the converter so you should drain it when you drop the pan. Have any luck adjusting the bands like adilts2002 suggested?
Later

 

if i knew how to adjust them i would. is it on the side of the case.i did take the pan off, there was a valve body bolt laying in it. i put it back in and put a new filter. i did not think about the convertor plug. they need a plug on the pan. i saw a little plug looking thing on the pass. side of the tranny right above the pan so i took it out and fluid came out but not fast. is that the band because i took it all the way out.i thought i put it in like it was.

 

ok i have an update. i drained it to the right level and no change it only does it mostly in 1st i have to put the shifter in 1st and barely push the gas repeatidly just to get it going from a standstill. my aod is just about shot. would a mustang 5 speed fit in it's place without much work. how about a 4 speed out of a 76 mustang 2 302. if i do go auto would a b&m starshifter work. my c5 has been under the shed for probably over a year. it worked when pulled. but if i can get a manual in that car i would be very happy.

 

i will pull the motor soon maybe start tomorrow or something.

 

Well I know the super coupe 3.8 had a 5 speed option so theoretically you could find the parts to make a manual tranny work. I don't know if the bellhousing is the same for the 3.8 as 5.0 so you may have to get a mustang 5.0 tranny, you will have to look into it and see if you can make the 3.8 clutch linkage operate a mustang t-5 or something like that. Should be able to do it though.


I double checked and there are no external adjustment of the bands on the aod tranny.


The star shifter is stated to work on c4/c6 I don't know of a reason why it wouldn't work with your c5 but call summit or jegs just to be sure. Could be as simple as they don't list it because, not too many people use the c5. later


Any reason why your abandoning the aod?
