troubleshooting slow take off/shifting

[Hexxus]

DTC P0868 is present.

Truck has slow take off from a stop.

I have read that there is a drain back issue for the torque convertor.

How do I confirm/fix that?

I read on another forum that if you check your transmission level when it is cold and it is about 1" above the hot mark, that would be an indicator you have this issue.

I checked the level today and after having sat over night the level was above the hot line still so that for sure is one problem.

Now I am looking for how to fix it. Personally id rather replace it rather then deleting.
I looked on the lines I believe to be for the transmission cooler and cannot locate the check valve.

I have read that the valve is on the transmission lines. Can someone point it out for me? https://imgur.com/gallery/WolBsWb

If I'm reading the other forum correctly, it's the anti-drainback valve in the spin-on filter located inside the transmission. When you lookup transmission filter kits for the 545RFE, you'll see the standard flat filter we all are used to seeing from back in the day and a spin-on filter similar to the ones we use for engine oil. It's POSSIBLE that the check valve you're looking for is there. As far as I can see, there is no check valve in the transmission lines unless it is internal to the cooler.

The kit you want has the spin on filter. Personally, I prefer Wix, but choose the brand that floats your boat.
