Being new to Crossfire I have noticed that when in the Summer shifting mode the trans seems to lag from first to second gear. I was "thinking," dangerous for me, that the front band might need adjusting. When to a garage that specializes in Mercedes and other European cars and asked about it. The owner told me there was no front band adjustment as it is all electronic shifting. Went home and looked in the service manual and it says that there is a front band adjustment and procedure for doing it. What gives with the different information from mechanic and service manual?
