AODE TC Shudder
I have a 94 F150 5.0 with Aode
Did an oil change last night and whilst underneath it I noticed a mild leak from the rubber trans oil cooler hose. No biggie. Just a 6" section of hose up by the bumper (allows for flex and easy replacement of cooler I'm assuming). Well I replaced it and now I have torque converter shudder between 3 & 4 at 35-40mph. I had no Trans issues before hand, and it only lost about 2 0z of fluid during hose replacement. checked fluid and its not low. I've only driven it about 15 mi since. Will it cure itself? is there an air pocket in there or something? any ideas? Thanks in advance!
UPDATE:
Just took it for a drive because I know I'm going to have trouble sleeping tonight thinking about this. Seems to be more noticeable in lower speeds. 25-30. So not limited between 3rd and 4th. All across the board. Replaced the U-joints and output shaft seal last week and had no issues, So I gotta assume that is unrelated. Tapping the Brake doesn't seem to deter the shudder, but its hard to tell because of the small window in which it occurs.
Please help!

F-series trucks never came with an AODE. It's either an E4OD or 4R70W. Check the transmission code on the door jamb sticker.
Regardless, both transmissions are electronic controlled. Pull the codes.

Thought it was an AODE because it says AODE on it.
Code on sticker is U

I think they are one in the same. Regardless, how do you pull trans codes?

Same way you pull engine codes since it's the same computer, find the EEC Test connector under the hood near the drivers side hood hinge and either plug in your code reader and follow the directions or put a jumper wire between the STI and Sig RTN pins, turn the key to run and count the flashes on the check engine light.

Unless you got a some trash in the line changing the hose of it shouldn't have caused this problem. Make sure it is TC shudder. When it does it just touch the brake pedal. If It stops instantly then yes it is TC shudder. If it is. Then change all the fluid to Mercon v and add a tube of Dr Tranny's shudder fixer. I am not a big fan of snake oil treatments but this stuff really works. It is a fiction modifier formulated for this problem.

Im having what i believe to be a similar problem in my !990 f150 AOD. it shutters in overdrive, at anyspeed under light to medium throttle. and this only occurs in overdrive the most significant shuttering occurs at 50 to 55, and it can almost throw the truck off the road, like it makes it almost completely undrivable

No, there isn't an air pocket. The return from the cooler goes to lube the rear of the trans then is dumped to the pan. There was air when you changed the hose, but it was gone in the first few seconds after you started the engine.
I think you're describing a misfire.
The W means it is a 4R70W.
They are not the same transmissions, but they are very similar. The 4R70W evolved from the AODE.
Yes you can.
That is also misfire. The AOD is immune from torque converter shudder. It can't happen in that transmission.
Seems to be more noticeable in lower speeds. 25-30. So not limited between 3rd and 4th. All across the board. Replaced the U-joints and output shaft seal last week and had no issues, So I gotta assume that is unrelated.

Just thought I would update:
Turned out the vibration was due to worm yoke and extension housing bushing. It probably went exponentially right after doing the U-joints because everything tightened up and that was the last sloppy thing left. Glad it wasn't a trans issue... and not every vibration is explained by misfire. So smoothly down the road we still go! for now..
Thanks for all the suggestions gentleman!
