86 computer controlled AOD transmission

[Harley17701]

i been interested in swapping out my 4 speed AOD tranny that is computer controlled in my 86 XLT ..... i would sooner go with a 3 speed auto ...... what other transmissions are available or compatible? ....... and ... how could i get around the computer line? ... or is there a better tranny i could get with the 3 speed auto and hook up to the computer on my 86??

You could go with a C6 transmission, but my question is why do you want to get rid of the AOD? :huh:

Good luck,

The AOD is not computer controlled especially in a 1986 . The E4OD is computer controlled but didnt show up till late 1990 . /emoticons/[email protected] 2x" width="20" height="20" />

Blade's right. the AOD isnt controlled by the puter. why exactly do you want to get rid of it?

Correct, the AOD is controlled by cable from the engine. A common swap is the C-6 3-sp auto. It is also non-electrically controlled for shifting. A swap will require a different bracket and kickdown cable than the AOD, and a changed in t-case shift linkage.

well guys .... ok if its not computer controlled then .... it connects to a safety switch on the transmission i know without this plug being on and connected to the transmission this baby wont shift ....... and this AOD transmission i lost one in it already when i had bigger wheels on it ..... if the plug is not hooked to the transmission it wont shift all but first and reverse ..... nor will the bronco even start if this aint connected to it ...... then what is it if not computer controlled? ... unless perhaps its a newer transmission and engine .... thats why i figured it was computer controlled .... and yes your right its also cable controlled but if that plug isnt on the transmission ..... it doesnt matter if that cable is working or not ...... it wont shift .... also someone might be able to help me out . it also shifts nice til i hit the Overdrive and usually kicks like **** going into and coming out of OD .... if someone may have some advice on this .....

that would be the nuetral saftey switch. basically keeps you from starting the truck in gear. if its unplugged, the comp doesnt know whats up with the trans so it wont let you start it. that doesnt mean the trans is controlled by the ECU.

about the problems, when was the last time you changed you're fluid and filter? it cant hurt to do it.

is your truck modified at all? sometimes if you are running larger tires on stock gears, the tranny will hunt for gears to find the right one

its stock and i was running 32's .... and i was going down a roadway ... and trying to pass someone i didnt hear no noise but right afterwards i lost OD and then as i went down the road lost 3rd and 2nd ..... so its possible i have the E4OD tranny .... ok you mentioned the neutral safety switch .... but what about that being unplugged and ..... not being able to shift? ..... i am just afraid to put any pull or what ever on the tranny i have in it now .... worried about taking another one out ..... and basically i felt with the 3 speed auto transmission ..... that it would be stronger perhaps ..???? i know when i had the 32's on it ... it even played **** on the highway going up hills and such ...... i thought with the 3 speed i would have more power to climb with beyond yet ... of changing the front and rear gears ..... and .. tranny filter change? .... since i had this beast this is the second transmission i had in it ...... and it still does the same ...... kicking going in and out of OD ..... as the old one .... someone mentioned to me its possible it may be in the rear or the transfer case its self causing this ..... i would call it slop ..... all i know i bought her cheap and with plans of fixing it up .... but the way it kicks into the OD i am afraid i am gonna end up breaking something

 

[Harley17701]

also there is no ... vacuum for the shifting either .... i hear the engine was changed and came out of a 87 crown vic..... but i cant think they would of changed the tranny ..... the only thing that is shifting this is ........is electrical or the cable but as i mentioned if the plug is not totally into place on the transmission it also dont shift all but 1st and reverse...... i have been a ford man but when it came to FI ..... i am lost with the computer crap and all ..... this has a 5.0 FI ....... so maybe this info will help .... completely stock no mods.

warning do not change the fluid or the filter .when you use new fluid it is too thin for the front pump .i found this out the hard way on a c6. then only reverse works if you want it and a good transfer case i will give it to you the tranny needs a front pump or you could rebuild it .i just switched my 88 to 4 speed manual. that aod is a bag of crap you would be much happier with the performance of a good c6 but the gas milege will be alittle worse.the aod works on the rpm of the motor

and always shifts really sloppy in my experiences.

LOL OK guys the AOD is NOT computer controlled the plug your talking about is round on the drivers side I believe and it contains the wires for the neutral safety switch and the back up light switch the only thing that may explain why you think it doesnt shift when unplugged is that it may have a lockup convertor in it I know they did this in the cars but wasnt aware of it in the trucks if this is the case the most it wouldnt do is shift into overdrive and actually it would but would feel funny . The AOD is controlled stricktly by line pressure for shifting and thats controlled by the cable that runs up to the throttle body thats why its so important for it to be adjusted correctly . As for not changing the oil and filter because the new oil is too this for the front pump . LOL have you been in for a drug test lately cmon tranny fluid is thin to start with it does not hurt to change the fluid in the transmission you hear all these horror stories of yeah billy bob went to the oil change place got his tranny flushed and it went out the next day well the rest of the story is he was beating the **** out of it the day before and burnt the oil so bad it didnt **** anymore and suddenly decides to get the oil changed on a tranny that was on its way out anyway . The front pump is a gear pump and would pump water if you wanted to put it in there the bearings may not last long but it would pump it . /emoticons/[email protected] 2x" width="20" height="20" />

ok yeah well your right its a round plug on the driver side ... but i also know if this plug isnt snapped completely into place and i know this myself because i had to snap it into place for the transmission to work properly ..... and no ... i know all i had was 1st and reverse ... without it being snapped into place even with the cable at the right tension ... without that being in place i never hit OD let on 2nd and 3rd ... i dont know guys its all greek to me .... and i will check in soon about having the fluid changed and right it may help .. i havent tried it yet. this thing being a daily runner has a long ways to come .... so anyway .. if these other transmissions like the C-6 arent .... the same hook up ...... how would i go about bypassing this hook up? i have test drove the 302 fuel injected before in an 86 eddie bauer edition and i noticed then it had the same or similiar problem with the OD ..... kicking going in and out of OD ..... i'm thinking perhaps i will go and look up a motor manual to figure out what exactly this plug does on the transmission lol ..... cuz i am puzzled with it all .... ...... and would a lower gear ratio actually help with power as far as keeping speed on the highway or climbing hills even if i were to go to bigger tires?

of course the trans isnt going to work properlyif that switch isnt fully engaged. sounds like your nuetral safety switch is bad, making your TC lock up and unlock, which would throw you in an out of OD. i dont think its that $$$ of a part, but check for codes first. the NSS should throw a computer code.

and i bet if you tried to use better sentence structure, your posts would be WAY easier to understand. just a suggestion
