Re: C4 to AOD

Great writeup! The little details are the meat. One suggestion - most classic Mustangs use the long rear axle pinion yoke. The more common standard short yoke is 1" shorter and cheap in every boneyard. Just by swapping yokes, you don't have to shorten your driveshaft. Might save time and bucks.

More details can help diagnose you problem, what year this aod (83??) ? rebuild? stock? wht t.q do you have?

What do you mean when you say "rough shift from 1-2"??


What do you mean when you say "when it shifts into 3 it basically goes dead"?? dose it feel like neutral and the engine is revving with no response from the AOD?

Try to describe your problem more accurate...

One thing you can do to get a better pic on the aod condition is to check the line pressure (middle port, next to the t.v pressure port), see wht numbers you get in "P", "N", "D" and the gears that dose work.... you can get the numbers here:
TCI - TECHNICAL INFORMATION: Transmission Line Pressure


There are people here that can help you much more then me, try to p.m "Pauls1950"

Smile Re: C4 to AOD

thankyou for the info very much! thats the problem with aftermarket parts and the people who make and sell them.i think most of em are chevy guys that dont care about fords anyway.everyone goes with chevy cause they are a lot cheeper to build, just remember you get what you pay for,lol. anyway i have a 1929 ford model a and just put a 302 and aod in it and just got the lokar cable in tonight and was lookin for info on how to adjust it out right. i did not know how important it was to have this all hooked up cause in my 1966 fairlane 302 c4 i never had a kick down hooked up and it ran and shifted fine. so thanks again and i'll get her goin in the morning!!!

X-Cell-N-T write up !!!!

Wow...that is a lot of detail!

NOT gonna get that in a set of instructions....

Here is an off the wall question....

...has onyone attempted to do this with a multiple carb setup that
uses a progressive linkage????

I was just wondering if I can incorporate an AOD with my small block
stroker AND my '63 Buddy Barr/Holley Tri Power???

...hhmmmmmmm

Re: C4 to AOD

Danford: Are you asking about the neutral safety wiring? If so just grab the plug on the side of a wrecker AOD, 2 wires & you have safety switch hooked up.
Skullnflame -Bout, 6 years ago, I had just installed an AOD & wanted to get it to a shop for other work, but didn;t have a clue how to run TV cable. I had installed a Lentech valve body, which really gives you ultimate control over the stock wonky, AOD shifting, & a call to Lentech told me to get her going-
Make sure there is no slack or tension on TV cable when at rest, then floor gas pedal, make sure cable isn;t binding, let it off an 1/8", just a tiny bit of slack at WOT, this allowed me to drive her to my shop.i did notice shifts were firm & well spaced.
When the shop checked my TV cable adjustment they asked -how did you adjust TV cable as its right on the money.
Lentech automatics techys are the best source of info re- AODs, or the later ford R70's & their valve bodies really wake up an AOD.

Re: C4 to AOD

Yes the neutral safety and reverse light switches on the side of an AOD trannie.
The problem is there isn't any junk yards near me to "grab the plug" from.
If there is one by your house, can grab one and send it to me?
Someone must have one laying in their garage or on the junk car in the driveway.
I just can't seem to find that person.
I've been searching the net posting here and there with no leads on this common item.
I did find a place selling new ones but they want $26 for it. Waaaayyy to much for
a plug you can "grab" from a junk car.

Talking Re: C4

I ordered the adaptors for the coolant lines and they work great. I installed a Finned transmission oil cooler but dont know how well it will work since i haven't fired the motor yet.

Re: C4 to AOD

Danford- I discovered that if you ask to "grab" that switch off an AOD, the yard says- You can have it once you buy the whole trans!
so, its not that easy to get one.
You can't use 2 generic ends? If I recall, the 2 poles on the trans are just flat poles, couldn;t you run 2 wires, with female ends & plug em on the trans switch?

Re: C4 to AOD

I was a little worried about adding to a 7 year old thread but I see activity from within the last year so here goes...

So the car is:
  • 1967 Mustang convertible
  • C-code replaced by a built 351W (estimating 425hp/425tq)
  • C4 replaced by a 1993 AOD from a 5.0 Mustang that has also been "built"
  • 2,800RPM Stall
  • Holley 750 using the Lokar bracket and TV cable
  • Factory shifter (P-R-N-D-2-1) so I have no "1" on the AOD
  • 20,000 pound "RV" oil cooler in front of radiator
  • AN fittings and braided steel hoses
  • Fluid filled pressure gauge that reads 0-100PSI but also shows 2 pound increments

I have mine set up opposite from the OP in that the shifter and TV levers are upside down but the inputs are correct. The trans has solid input shafts (to eliminate a known weak part of the AOD) and a shift kit with an aftermarket (B&M I think) valve body, that is about all I know since Transmissions are not something I fully understand.

So I adjusted everything as specified by Lokar (TV pressure and cable-tension etc.) and the car drove poorly, shifting 1-2 then 2-3 at very low throttle and not coming back down to 1st gear. So I found/read this article, followed advice as much as possible and it is MUCH better but still needs some work and tuning.

I've got the little acorn nut with allen screw locked down and am trying to make final adjustments using the conical nuts on the Lokar cable to make tiny adjustments on the tension trying to get it at the 2-4PSI at idle as recommended by the OP. Sitting there at 0 PSI @ idle I begin adding some pre-load by turning the threaded tube and the pressure doesn't move, turn a little more and nothing, turn a little more and it jumps from 0 to 11 with just the slightest possible change. I think with some luck and multiple attempts I could get the number nearer to 5 but is it supposed to be THAT sensitive? I'm talking about a 1/16-1/8 turn of the nut here, the cable movement must be less tha 5/100th of an inch. I cannot see that degree of sensitivity being correct or normal.

What should I do? I'm worried about burning up the Trans just with small 1,000 yard test drives. Is 10-12PSI at idle too much? The brakes easily hold it back and from a dead stop the car rolls forward slowly (as opposed to speeding away) when I lift off the brake.

Re: C4 to AOD

A little extra line pressure at idle won't hurt, and will firm the shifts a bit while holding the clutches better. It might 'bang' a bit on high-idle cold shifts. Up to you on the feel. However, I would keep a close eye on it for a while, as the adjustment should not be that sensitive.

Re: C4 to AOD

Thank you so much for the reply. I know very little about what happens inside an automatic. Is there a certain line pressure at idle I should be worried about? What is it that causes the "you will destroy the AOD in a very short distance" claims that I am warned about over and over?
