MB's early automatics, eg the 4-speed in the Pagoda-vintage cars, were designed not for smoothness but to lose minimal energy in the tranny and to shift faster than a manual could be shifted by a skilled driver--"faster than the fastest hand" is a phrase I seem to remember from a Road & Track test. Obviously, MB has evolved its technology and its goals, but the 107 comes from a time when speed and efficiency were still more important than Caddy-like smoothness.
