Transmission adaptive computer programming
Believe it or not this procedure actually worked on my e38 [no start button - i used the key and switched on ... but not to start position. May not be the solution for your transmission problem but what the heck, the price is right !

If I drive the car in the manual shift mode it does not do this. It seems like it has a bad sensor or the tourque converter might be on its way out. Has anyone else had this same problem? If so , what was the end result? Thanks Bruce
but I was led to believe that there are some routines to reset the adaptive gearbox on the E60/61.
First one is this...
You put your key in/hit start button/key switch so the ignition lights of the car come on but it is not started.
Then hold down the accelerator, to the floor for 25-30 seconds.
If you listen, at about 25s exactly you will hear some "noise" and that is the gearbox "resetting" itself to factor specs
Try it... Can't do any harm..
