any feed back on the new e500 with the new 7 speed transmission? i wish they didn't built it like the c class. i have a c320 sports sedan and my trasmission doesn't lock when i put it to drive from neutral. this happens when i put it on neutral while gliding on the freeway to save fuel. i need to stop the car and put it back to P and back to D. that when it's going to lock again. it's under warranty but, it's giving me lots of aggravation. they can't seem to find the problem. all they did was to reset my computer box.
