Basically there's a retainer plate (you can see it in one of the pictures towards the end of the video, that has maybe 8 screws on it and runs the length of the solenoids. That is all that holds the solenoids in. The solenoids have o-rings on them that seal pretty tight to the holes they are in, so it takes a bit of a yank to get them out, but ultimately that's it. They don't screw into the valve body or anything like that

I wish I could have gotten a good video of swapping them--that was the part I wanted to record the most but I ran my memory card full on accident unfortunately.

I found a video on youtube that shows disassembly of a very similar mechatronics unit (maybe the 5HP or something like that?). I'll post it when I find it.

Here it is (below)

Note that the wiring harness doesn't really exist on the 6HP. It's a big plastic piece with connectors that line right up to the connectors on the solenoids, so that part is nothing like it. But removing the actual solenoids is the same.

And obviously ignore the whole taking the valve body apart part--no need to do that to change solenoids.

Thanks schpenxel, one more question in relation to INPA. I am not very confident with INPA, but following your post, I got a cable and somehow got the INPA 5.0.1 with EdiABAS 6.4.3/7 working. Can you please tell me exact steps how to clear adaptive transmission memory? In my scripts, under transmission, I can only see how to read and clear the errors in transmission, but how do I clear the adaptive transmission memory? I would really appreciate the information.
