W123 Manualy shifting auto Xmission, S means 2nd and 3rd?

So I took a friends advice and tried manually controlling the shifts for a faster take off. So I shift into L and I get first, shift up to S and I stay in 2nd gear until about 3500 or so and then the transmission shifts again.

Is this normal behavior?

L is 1st gear only IIRC, S brings it to 2nd and D will pop you up into 3rd then 4th...

the dots on the spedo indicate the best shift points supposedly

Well then it looks like something is severely screwed up in mine!

S has always been 2nd and 3rd gear for me... L is 1st only.

When I had an automatic it was always L= 1 & 2 (Shift into 2nd at about 4000rpm) S= 1-2-3 and D=1-2-3-4

Just as a note...

Mine had PRND32 instead of PRNDSL like the older cars do.

D = 1-4 Normal shifting, first gear start.
3 = 1-3...I've noticed slightly higher shift points in 3 than in D, but that may just be me.
2 = 1-2...If accelerating from a stop in 2, it will start and stay in first gear until at or very near redline, then it will shift to second and stay there. Shifting into 2 while driving will drop to second if within the second gear speed range.

So if you wanted to shift it like a manual, start off in 2 or L, get to the appropriate RPM, briefly shift to 3, then back to 2, wait till you want to go to third, then shift to 3, wait till you want to go to fourth, then shift to D. Pain in the butt, but it works. Pretty easy to do by feel with the MB shifter arrangement too.

well that's encouraging. At least now I know my transmission isn't screwed up!
