I have a Merc E320 - The vehicle starts great. After 2-3 mins of letting it heat up - I then engage in reverse to enter the road in front of my home. Then when I place it in drive, well this is the odd part. I need to accelerate slowly until the vehicle warms up some more...then the vehicle will change gears fine. If I just push the gas very quickly, the gears or tranny have a hard time changing & at times the vehicle will stutter changing gears. But after 5 mins of driving - all is fine. Odd? Any ideas would be helpful. Yes - maybe the fluid for the tranny is low or maybe the filter needs to be changed..I dunno -
