When idling in gear I feel I am using excessive brake force to keep it from creeping. To the point the brake even groan a little at release and stop. It pulls too hard at idle. Is there a stall speed adjustment or firmware upgrade/adjustment to solve this or am I stuck with a faulty torque converter?

What is causing the problem, and how do I fix it myself.

I don't know if anyone has had this issue with their vehicle (approx 47,300 miles registered). This problem happened recently. At a minimal speed (approx 3-10 mph),there will be a rough "clunk" underneath the vehicle when releasing the accelerator/gas pedal. It feels as if the vehicle is switching to a lower gear or something rather. I dropped the vehicle off at the dealership almost 5 days ago. The service department is presently troubleshooting the problem. They mentioned it may need a transmission fluid service. I'm thankful that they arent just shot gunning a part. Has anyone here experienced the same issue? Fix? Thank you so much for any input.

The navigation system withjin the ML350 provides an estimated time of arrival. I have noticed that the time varies significantly as I drive to my destination.For example I start out on a trip and the NAV system states it will arrive within 2 hours. It will change to to 3hours plus until it gets close to destination and then refvert to correct arrivasl time. I checked with dealership and they have no software updates ( 2 months ago) Anyone experience this issue
