Having a delayed 2 -3 shift is normal when cold. MB does this to help heat up the cat converter quicker to reduce emissions.

I'm not an expert on the 722.6 transmission, but I believe the main updates were to the valve body.

However, the 722.6 has proven to be an extraordinarily good transmission.

It can handle enormous amounts of horsepower. It is used, without modification, in all the AMG models, in addition to the SLR McLaren Mercedes supercar.

It is also used in the Chrysler 300C and Jeep Commander cars with the Hemi.
