Anybody have any experience with that? Thanks

I am not sure what the BMW tool is for. You remove the cooler from the bracket... DO NOT Disconnect the hoses from the cooler, you could drain your ATF.. In the diagram below, you pull on clip 13 up and then pry with a long screw driver to remove it. The full assembly will come out at 12 (circled in red)

Thank you. I finally got the part in I was waiting for and am going to continue on this project today. Where exactly is #13 and what does it look like? I'm having a hard time finding that. Thanks for the help. I hope to post a recap of the problems I faced as a relatively inexperienced DIYer.

I got it. That was much easier than I made it.

good luck and enjoy the ride. My bmw was out of commission for a few days because of the disintegrated thermostat which was very inconvenient and unplanned :-).

got the coolant leak stopped. unfortunately a terrible leak apparently out of the transmission cooler occurred while driving it around the neighborhood. got the transmission failsafe message and it shut off. leaking black fluid like crazy. tow truck time. i hate automatic transmissions.

Oh man hopefully it's a busted line and that the truck shut off before you caused any damage. Good luck.
