I saved this old thread from peachparts while back, you may find it interesting, starting with post #9, http://www.peachparts.com/shopforum/mercedes-benz-performance-paddock/30755-1st-gear-start.html
"Nice try! Go ahead and pull that spring outta there and drive the car....it'll start off in 1st gear all right. Then:
1. the car will remain in 1st gear until you feather the gas near redline at which point it will shift to 2nd for a second then engage 3rd.
2. The 3-2 brake shift will be affected (almost missing).
Your diagram doesn't mention any modification to the check balls, nor enlarging the bore on one of the passages, etc.

If I'm not mistaken, Satish known here as well?

The picture is correct.
FGS and SGS VB's use different valves, with the spring located in opposite positions. The picture is showing the SGS setup with a note that FGS is different.
Satish is correct, if you remove the spring you do get FGS, but the side effects are intolerable. One of my cars was delivered with this modification and it was awful. Had to replace the VB to fix it.
If you want a FGS VB, I think samiam44 still has a couple for sale.
I haven't checked in a while. Search the classifieds and see how many are out there, unsold. IMO, a unit that has been tested (meaning, you drove the car and confirmed all upshifts / downshifts are normal) is worth a bit more.
That said, I haven't seen any "Wanted" listings for FGS VB's. Which is odd, considering what a great upgrade it is.
Yeah he’s known pretty well around these circles. Like Klink, Jono and others, a bit legendary. I’ve known him for about 20 years. He’s one of the reasons I have a 500E, although he wouldn’t sell me his when I was looking. But I’ve been happy with my journey, and he has helped a bit.
One of the things I’ve been wondering here, is whether an E5E with FGS can easily retrofit the W/S/E shift mechanism.
maw
maw, it's just an E/S switch for the W124. All North American models come fixed in the "Sport" setting. The switch allows choosing an "Economy" setting with LOWER shift points. Sure, it can be retrofitted, but I doubt anyone would want it. Alternately, the factory switch can be used to control an electronic FGS setup to switch back & forth between FGS and SGS.

I think the W210 started with the W/S switch (Winter/Summer) which not only changes between FGS and SGS on the electronic 5-speed 722.6 tranny, it also changes the reverse gear ratio!
