2003 540 Msport Dinan 2 transmissing "thump" question.

I have a 2003 540i M Sport with Dinan Stage 2 engine and transmission software, cold air intake and free flow exhaust. I am experiencing a sort of little kick, thump type feeling when coming to a complete stop. Current mileage is 135K. I do a lot of city driving, usually in normal D, but sometimes use the sport option. I believe I experience it more often and prominent when the car has been used a lot that day. I am hoping this might be a matter of old fluid, and a fluid swap will solve the problem and prevent further deterioration. But I am not sure. Any advice? Does this have something to do with the Dinan software?

Sorry about the thread title typo. I can't edit it.

I would do a fluid and filter change. It sounds like it may be a little low on fluid

Is the thud caused by a slight idle drop when stopping?

I wouldn't do that. That could cause the transmission to go even quicker. Use a scan tool and see if there is a shadow code. Pray its electrical. Could be the kick down switch causing that

Explain to me how a fluid and filter change could cause the transmission to go even quicker.
