Loren: I was amazed, but that was all it took. Let us know if you get similar results. The same service also solved a slightly late 1-2 upshift, and a slight 2-3 flare. Who knew? Trans has been shifting perfectly and consistently for 45k miles of mostly highway driving since.
One of the things I like best about the 722 is the kickdown button that allows you to get full throttle without kickdown. Because of the broad torque band on-boost, I find I almost never kick down from 4th on when wide open up steep hills and during passing, which I think saves trans wear. Above about 55 mph or so, 4th pulls just fine. Every other AOD trans I've driven didn't allow you to "opt out" of kickdown at WOT, and was constantly dropping out of OD. Of course, the numerically high final drive ratio helps, too.

(Drain and filter change) But I started wondering if there was really any hope for that being a good solution. Glad to know that is a possible solution. >Had the same symptoms with my 82 300SD.

Never had to mess with it, and never had to take out an engine, head or trans on an 86 or 87 yet. good to know, I guess. >Stuck kick-down switch? > >-Max > >________________________________ > >From: mercedes-boun...@okiebenz.com on behalf of Dieselhead >Sent: Thu 9/23/2010 9:04 PM >To: mercedes@okiebenz.com >Subject: [MBZ] auto trans diagnosis Q > > > >This is an 85 380SL.
