3rd drain/fill of transmission. Sadly, the fluid still looks pretty dark and nasty. I did a pan drop and filter change on the first go-round. The shifting is noticeably quicker even after the second drain/fill.

On my e83, there's a transmission oil change reset in DIS (and presumably ISTA), but I couldn't find it in ISTA for the e53. I can't get my DIS to connect to the e53 for some reason, so I couldn't check in there. Anyone know if there is a reset for the e53?

I've been mostly just working on this thing since buying it a month ago. Tomorrow she goes on her first ski trip into the mountains.

AM.
