AOD experts...

I fear I have an issue caused by the culmination of engine, gearing and perhaps other factors that may prevent a solution. My AOD does not downshift well at all. While in OD, it won't downshift. No big deal. I just keep in 2 during "city" driving and throw it in OD when on the hwy.

The problem: In 2 (cycling from 1-3), it really wants to stay in higher gears putting the engine at or below 1000 RPMs. The low power band is killing me at times. I understand this is a governor issue, but is the governor even adjustable?? Any ideas would be great. It is the only issue I have that is hampering the joy of driving my rig.

What have you done to your engine/transmission? Are they stock etc? Have you installed a shift kit? Is this a built AOD?

This sounds like a mis-adjusted TV cable. Take it to a trans shop and have them check it. It took a while to get mine dialed in. If it is a TV cable issue, get it fixed soon, or you will burn out your transmission very quickly.

Find a good schematic of the AOD valve body (it's pretty complex). Take everything out of it and lay it all out in a VERY organized manner, clean everything up with brake clean and put it all back together. While it's out you can take the accumulator valves out and check them out aswell. I've been told by a couple of tranny guys that the Ford AOD is one of the most complex valve bodies to work on.

I'm suspecting you may have contamination in one of the circuits. Or the TV cable got out of whack. Put a pressure guage on the pressure test port and see what it says. I don't exactly remember the spec's but the TV cable is easy to adjust.

I wouldn't take it apart first, my AOD acted the very same way until I got the TV cable adjusted. Check it first before ripping the valve body apart.


Here is a good website on the AOD

with regards to the governor, the truck is a lower speed type, meaning it will make the gears shorter, the car aod governor is a high shift point type.

Sounds like you need to adjust the TV cable tighter- this will bring up the pressure a little and hold the shifts a little longer (not to high though). It not down-shifting out of OD and quick shifts are a sign of the pressure being to low. I have a low gear set in mine and use the mustang govenor, I have to keep the pressure up a little for it to shift ok- a shift kit helped dial it in

Definitely the tv cable and wylie said it best. get it adjusted asap or you will have to go inside your aod...

I thought the tv cable would adjust upshifting. If it affects downshifting as well. That is great news. It does shift a bit early anyway...just more pronounced of a problem when downshifting.

Thanks for the advice!

Replace the TV cable grommet on the throttle lever, and THEN adjust the cable. Read this caption:

Thanks Steve...for such a small investment I will definitely put the brass grommet on.
