Auto Transmission Question?

[white lancer]

I was reading a thread on the X3 forum this morning about 2007 X3's with a software bug which affected the transmission during hard acceleration and deceleration. This seemed to be resolved by a software update.

Well I noticed on my 2004 X5 3.0i Sport that I have similer issues which have never caused me concern - I have just lived with it and I did not think it was an issue until I read the X3 thread

issue #1 - my accelerator pedal is extremely sensative, I literally have to touch the pedal and the car is off. On my X3 for instance you have to depress the accelerator pedal a centimeter or two before the car starts to move, then more gentle pressure sees the car accelerate gradually. If i did the same with my X5 it would take off like a rocket! I literally have to feather my accelerator pedal very gently to get a smooth acceleration

Issue #2 - When I accelerate hard from a stand still such as the traffic lights the car takes off like a rocket in first but won't select second gear until it virtually red lines. This is when the car is in normal drive mode. often I have to back off on the accelerator pedal deliberately to enable the car to select second gear

Issue #3 - I noticed yesterday that when sat in traffic for about an hour I would accelerate very slowly to say 5mph to catch up with the car in front but when I take my foot off the accelerator pedal to let the car coast a little before applying the brake pedal, the transmission seemed to "kick" a little when comming out of first gear. again not an issue but very annoying

has anyone else seen any of these issues? I am wondering whether there is a software update for my X5 to get rid of these issues?
