Plug adapter and a connector? They may have replaced the electrical boot maybe.

The 7 quarts of tranny fluid is interesting... The pan only holds 4, and a leaking connector (due to its elevation) can only dump about 1 quart maybe. So if they put in 7 then they probably did some interesting things, like pull off the cooler line and drain that way, which explains the brass ring they needed to install it back again I guess.

I hope they filled the tranny fluid right.... My last dealer visit they did not fill it right, I had to add some with my dipstick+temperature-guessing. It shifts great now. Stupid dealer.
