Sorry to drag up an old thread, but I just had the valve body mod done on my 300SL, and what a difference!
Starting in first gear makes this car a WHOLE lot more fun to drive!
I have no idea why they designed it to start in second......

I think that on the six cylinders, it always started with the first gear?

I do not, but I can try to get something from my mechanic. He said it wasn't difficult, but he knows his transmissions!

I know this is an old thread, but having a new to me 300SL I have a question. This is a 1992 5 speed auto. I can only count three shifts. Does this year transmission start in first? If so I should count four shifts, right? Does anyone have an chart that shows at what RPM the tranny will shift? I am at 3000 RPM at 80 mph, so I think I am getting 5th gear, so maybe I am having a second gear start. Any ideas?
Thanks!

when you start normally it, it starts at 2nd, then 3rd then 4th and 5th comes only when you redline at around 220+ km/h

if you floor it when first starting the car will kickdown a gear and start at 1st, if you lower the gear lever to 2nd when starting off, it will start at 1st then shift 2nd

My 91 300SL 24valve starts normally in 2nd gear and shifts into 5th at 80km/hr.

I'm confused, but I am in the US. One says 80K which is around 50 MPH. Another says 220K which is 136 MPH. Don't usually go over 100 MPH, so I would never see the fifth gear change. I think that is wrong. Can anyone confirm?
Thanks again for all your help. You guys are great.
