We bought our '05 late 2018 with 53k miles & have put another 12k on to this point. We're not having any specific issues, but i was thinking about changing the transmission fluid & filter soon. From outside it looks like the pan was last sealed with black RTV silicone - does that suggest that the pan was likely previously removed? I'm guessing that the original assembly would have been with a rubber gasket and that no excess material would be showing outside the edges of the pan...

 

according to the folks @ BobIsTheOilGuy,
also, f.y.i. - the manual calls for "service fill" of 4.0 qt, but ours drained out 5 full qt when i dropped the pan to replace the filter - so be prepared with more than 1 gal to refill if you do this job. 5 qt refill brought it right back up to the proper level on the dipstick as well, of course.
