Type F in a AOD?

[hav24wheel]

I'm planning on replacing the pan gasket and filter on my 83 LTD, at the same time doing a shift kit. I have plenty of Type F at home, so is that stuff good enough to run in my AOD?

If you want to replace the trans again, go ahead and use the type F.

Why is it that a fluid change tends to doom the AOD's? Mine was flushed and the fluid changed maybe 10K miles ago and im at 114K...so i guess i lucked out.

[hav24wheel]

Well i have not replaced the trans in this car ever, its got 119,000 miles on it and the trans fluid is looking kinda dark. i just figured if i where to change it with what i had at the house it would be good, but if Type F will kill the trans, i'll go buy the Mercon V.

[DuceAnAHalf]

type F is bad. mercon III is what came in it. Mercon V is good, but expensive. V is required on all Ford automatic transmissions after 95 or 96 IIRC

[hav24wheel]

The only reason i asked about Type F is i run that stuff in my Off-road rig with a C6(1978), i have beat the hell out of that trans, heated it up untell you could smell it in the cab, nutral drops, go from reverse to drive without letting the engine drop below 3 grand, and that trans is the ONLY thing i have not replaced. i have had it for 6 years. i do change the fluid when it gets bad though...

[mrltd]

A C6 isn't an AOD, they use different fluids.

[DuceAnAHalf]

if you use Mercon III in the C6 you can get a little firmer shifts. at least thats what i have heard. my aftermarker C4 requires Mercon III, but thats cause of the special clutches and bands i assume

[hav24wheel]

Well the C6 is going to get Type F tell it dies, its got a shift kit, and a 2500 stall converter in it, shifts nice. As for the AOD this is the first one i have had, thats part of the reason i asked about the fluid. i do know they don't have a very good reputation(sp?) compaired to the C4, and C6. I'm still learning when i comes to this trans.. hell i was hesitant on adjusting the kick down on the dam thing, due to reading about peoples problems with them.

Dexron/Mercon III or V in the AOD only. The only place for F on a box is the power steering pump.

Ssshhhhh!!!! People around here HATE C4s!

Just a polite little reminder....AOD transmissions don't have 'kickdowns'. That's a throttle valve cable, and very sensitive to monkeying around with it....

I love 3 speed transmissions. Just not with my 4.10 gear.

The only cable on my trans is the speedometer cable, it has a rod from the TBI to the side of the trans.....

[1987cp]

TV cable, TV rod, does the same thing.

[Archangel]

Basically where Pirate and 1987cp are getting at is that you can run your C6 with just the vacuum line attached and the kickdown is purely optional, whereas the AOD don't have a vacuum line and instead uses that rod to adjust the line pressure so adjusting the rod can save or kill an AOD.

Also, what they said on the fluids, AOD takes Dextron/Mercon III, which is your regular trans fluid that can be found about anywhere for like $3 a quart. Type F has different hydraulic properties, and the AOD valve body will not tolerate it for long.

[hav24wheel]

O ok.. i see now. i guess i really have not looked at the trans too much yet.. i have read about how to set the tv cables, but have not really found too much about the proper seting on the rod settings... off to the "stickys" i go...

[Archangel]

Well you're actually supposed to do it with a pressure gauge installed in one of the ports on the passenger-side of the trans, but mine I just set it to near max TV pressure - unhook cable from TB, manually move the TB to WOT state, yank on the cable till the trans gets to WOT state, then back off the cable a tad and hook it back to the TB lever.

Be advised, however, that the TV rod on the early AOD works opposite to the cable found on later AODs - when a cable disconnects the trans goes to idle line pressure and you burn up the clutches, whereas when the rod gets loose the trans defaults to WOT line pressure and you can really do much damage to it at all. Not sure as to why Ford went from your setup to the cable one, especially since the same exact logic can be executed with a cable as well... Take a pic of your TBI linkage tho, and post it here, as there are two ways the TV rod can be hooked up to the TBI and adjustments of those are totally opposite, and I'm not sure which setup Ford used.

:worship: you are the first person i heard say that critically correct information.

[Archangel]

Nope, not really, Thain repeats it times and again whenever that question comes up, but no one seems to listen.
