Datacard says the red beauty has a 717.400 manual trans. Anyone know the ratios? I found
this post that says 5th gear ratio is 0.813.
I believe both the 190E-16 and R129 300SL had close-ratio manuals with 1:1 fifth gear. Most others had overdrive fifth, but it's hard to get official data on the exact ratios for specific boxes...
