It just may take a week or two of driving for it to figure it all out. There are no serial numbers or anything on the solenoids that the computer can read, so it doesn't really know if they're new ones or anything like that.

Sorry, after I stripped that pan bolt I forgot about the video for a bit. Yes, you have to remove the sleeve. It was so cramped up in that area, that I actually couldn't get it completely out of the car--I could only get it out of the transmission then just left it up in the car wherever it was and called it a day.

There's a transmission mount at the rear of the tranny that if I could have removed, I think I could have gotten the sleeve out. I didn't have female star sockets on hand though so I couldn't get it out, but to answer your question, YES it has to come out.
Thanks, one more question, does CTSC actually provide a guide how to replace the solenoids on the valve body? Is it simple un-screw and screw back in or can you share any guide you followed? That would be much appreciated as I am planning to change all my solenoid in my next ATF oil change.
