hi all, my e60 has the gear shift 2-1 when going fast to a full stop jerking problem. i bring it to authorized dealer, they recommend me to change atf oil n do adaptive memory reset. after i took the car, the problem fixed.. no jerking at all shifting from 2-1, as well as in manual mode.. after that the problem came back again in 2-3 months time, after long research for this gearbox problem, i conclude it was due the the adaptive gearbox memory.. which has to be clear.. n then my mechanic clear the adaptive memory. it solves the problem..
whenever u felt jerk from driving fast to a full stop, you can try shifting from M2 to M1 when in stationary, if it does jerk, find a mechanic that can do gearbox adaptation memory reset. and then perform a gearbox adaptation.
