Hello everyone! Im looking at a 2012 c63 amg with the p31 package and it has 45,000 miles. He showed me that when the car is in reverse and you put it in drive while it's still rolling back it takes a little bit of time to engage and start moving forward. He said that's normal on these cars, has anyone tried this? Let me know if yours does the same thing! Thanks.

Yes. MCT equipped cars take a few seconds sometimes to engage in gear. Perfectly normal, my car does it too.

Very normal my car does the same thing. It doesn't happen all the time but nothing to worry about.

not sure about the 722.9 transmission, but some transmissions do not like being shifted while car is moving. i'd avoid doing it if you can.

Normal in my 13, but you should come to a complete stop before shifting and that also seems to make it shift faster into D if you are dead stopped when you shift.

Don't all auto boxes do this?

I suspect that changing from reverse to drive or vice-versa while in motion cannot be good for the clutch packs. You have all the momentum of the 4000 lb car fighting what the tarnny is trying to do. I suspect this will wear those clutch packs a lot faster. Why the hurry?

This is my thought also and I think Mercedes programmed it to not engage until you are stopped, so if you shift while rolling, it just waits until you stop then starts to engage the clutch once stopped hence the delay.

I find myself asking "why would I want to do that? What purpose could it possible fulfill?

If you only looking at the car I would be looking elsewhere. If that is how yer man drives it you have to wonder (1) what 45000 miles of doing that to the transmission has done, and (2) what other little "tricks" he has been using on the car. Not a car I would want to be buying!!

Yup!
