Just curious what your truck idles at.

I adjusted the TV cable looser to the point where I didn't get the clunk in the shift and the harsh downshift, but that put the TV pressure far too low -- and if I understand things correctly, low TV pressure is what destroys these transmissions. What I did notice was that the return spring was a little weak on the transmission, so I added a helper spring which ensures the arm on the tranny returns to it's proper rearward position when I'm not pulling on the throttle. I then adjusted the TV cable tension at the throttle body such that there is 33 psi with the spacer tool in place, 0 otherwise.

It still clunks and bumps a bit, and the downshift isn't awesome (a little harsh). It still whines when I'm sitting stopped in drive (when moving even slightly the whine goes away), but it is better. The fluid level looks good, and it isn't foamy / bubbling so I suppose that's it. There are probably fewer days ahead than behind. When it blows up what do I do? Do I bother putting a C6 in it or is it easier to put another AOD in and baby it? I must admit I appreciate the mileage the AOD can get me; I don't haul too much stuff with it anyway. I would probably need a doner truck to put in a manual, I assume.

I realize this thread is rather ancient, but I recently came across some information that contradicted information that I have posted. Above, I'm talking about using an equivalent to a Ford spacer tool to adjust the AOD, T86L-70332A. It seems that some forum references online suggest this tool has a thickness of .275". I recently was looking through documentation online and can't seem to confirm this with any document from Ford or after market vendor. However, I did recently find this document:

https://www.jegs.com/InstallationIns...555-603106.pdf

The document provides instructions for adjusting the AOD. This document has dimensions for the T86L-70332A tool and those dimensions contradict what I reported. The doc lists thickness of 5/16" = .3125".
So if you happen to be reading this thread and want to adjust your AOD and are machining (or printing or however manufacturing) a T86L-70332A equivalent, be aware that I'm not sure what the thickness should be, but at least I have found one document that specifies it should be 5/16".

.... A closer read on those instructions posted above state that if you are using their 5/16" tool, adjust pressure to 25-30. If you are using the Ford tool (T86L-70332A) adjust to a higher pressure of 35 psi. This suggests the two are of different dimensions. Man...
Here is a forum post where someone has some pictures of them measuring it (approximately .25").

I find that the best way to set an AOD is full throttle, full TV pressure.

I've done it with gauges and setting the pressure and using the tool. They shift way early and don't want to downshift.

That was so Ford could meet Federal emissions and fuel mpg requirements.

Are you saying you just pull the cable all the way out and lock it there 100% of the time? I am all for that if it actually works without breaking your neck or the driveline when it shifts.

Full throttle= Full pressure.

They run much better like that IMO.

That sounds like the factory procedure on the cable types. Push the little button to release the sheath of the cable, hold the carb or the throttle body wide open, and then re-latch the sheath. On the original setups they have the lever arm ratios and the throttle travel all figured out with the trans pressure.
