I had my 2007 ML320CDI into the dealer for repair of the AirMatic, and made the mistake of asking if there were any software updates for the tranny. I told the SA that very infrequently I would get a very minor hard downshift from 2->1 or 3->2.

Four days later I got it back. They flashed the software and then got some sort of DTC, so they replaced - depending on which time the SA was telling me what they did - either the clutch pack or what used to be called the kick-down-cable. This part had to be ordered and required removal of the transmission to R&R.

I picked it up today. I didn't notice any hard downshifts (they were almost unnoticeable before I brought it in, anyway); but the transmission, which used to be silky smooth on all upshifts before, now has a definite "bump" each time it shifts up a gear - even on gentle acceleration.

Could this be because it hasn't completely adapted to my driving? Thoughts?

(Remind me never to mention minor niggles to the SA again!)
