My transmission has been getting very rough lately. It helps if I change the gears myself, from 1 to 2 to 3 then to D. My questions is whether this hurts the transmissoin at all, or is it just like it doing it itself? By the way, I have a '86 735i. Could someone explain to me exactly what the 3-2-1 option for my transimssion does??? Thanks, Kevin ------------------------------
