Driver's window - Sometimes when I pull the switch all the way up to close the window in the "automatic" mode, it will travel all the way to the top and immediately reverse back down to where it started. There is nothing obstructing the top seal - appearantly the regulator thinks the window hit something before it was really all the up. I sort of liken it to the safety reverse feature of an automatic garage door opener. Has anyone here ever adjusted those things? Any advice before removing the door panel and operating on it? I don't want to break any trim or create rattles in the door.

Thanks for any help. The education continues.... (I never did find that doggone trans dip stick,)

Oh yeah, one more question. What brand of oil filters do y'all use. I always used Mann on the 740. I see FCP sells the Mahle brand for about $5 each and claim its the same as OEM. Opinions?
