A442F Transmission problems.

are you checking the fluid level with the engine running? where is the level at? I'm sorry but need to start with the basics. it does sound like a low level.

I've been checking the fluid levels with it off. With the truck running it sucks the level down to the bottom of the stick. I experimented with levels yesterday. I had the level at the top end of the cold range on the stick. I let it run and it sucks it down the bottom of the stick. While it was running, I added another quart to see if that would make a difference, and no change to the symptoms. The extra quart, it then pushed over the top of the hot range once it was warmed up, so I let it back out. So I promise, it is not at a low level.

I have had a A340 at low level and I know the symptoms, none of what this is doing is remotely close to that.

IMO if it shifts fine manually then it not the fluid.

This is what I believe as well. If it was the fluid, then L and R would be much the same story. But they both work perfectly in manual. Which is why I eventually settled on solenoids. Having replaced those as well as the filter with brand new OEM ones, I don't think that's what's going on either.

Have you checked the wiring harness on the side of the transmission ?

It depends on how fast you're driving when you "come to a stop". The torque lockup disengagement is lower rpm/speed than the engagement rpm/speed. And the fluid is in the torque converter, so it matters what fluid is in there.
