BMW F10 automatic transmission jerking and kicking

520d530d

Why does the F10 automatic transmission creep and jerk when cold?

When cold, the torque converter lock-up does not engage, so the car creeps at idle and pulling away may feel slipping until the oil warms up. Most jerking and creeping eased as the oil temperature rose to about 90-95 degrees. A kick from P to D does not necessarily go away as it warms up.

What fixes the 8HP transmission kicking when shifted into D?

The lasting fix was a transmission oil change with a flushing machine, resetting the adaptations, i.e. learned values, and a software update. Resetting alone helped only for a short while. Too little oil can also cause clunking, so it is worth checking the oil quantity.

What other than the transmission can cause jerking or slipping?

Unevenly worn rear tyres, worn turbine blades, and worn engine and transmission mounts, rear support mounts and propshaft joints. A whine in reverse and a lurch from P to D are usually characteristics of the 8HP transmission, not faults.
