FATAL-J

Yeah its a 2002 318i with a triptronic gearbox and has done 107k's im from west auckland

i recently found out a problem in my e46 when i start it up and put in reverse or even drive the car starts to jerk a bit and then drives on normally its an automatic so im guessing its something to do with the gearbox or could it be my brakes sticking to the rotors? has anyone had the same problem?
