MBeige WV240D, if 79Mercy's '79 280CE's engine and vehicle speed match yours then this info should also apply to your car

That info came from here

to loss Some W126s start in first and some in second. I'm not sure about the Euro versions, but my 380 starts in first and came that way from the factory. The 560s start in second, and you could either get a factory first gear start, or an after market for them. I believe the 420s start in second as well...

So my guess is, anything lower than and including the 380 motor should start off in first. Anything bigger than 380 should start in second unless you're really on the gas, or you're lucky enough to have a factory first gear start module or a Bergwerks module...
11-25-2007 03:21 PM
79Mercy You should have 4 gears. Do the w126's start in 2nd?

Merc_aficionado Stunning car! One day I will own a mint W126!

Are you sure that wasn't second? My manual says my top speeds for each gear (with an automatic) are:
1st: 27mph
2nd: 59mph
3rd: 97mph
4th: 127mph

max engine speed: 6500 rpm

wv240d 125km/h=77mph. Mine would be doing a good bit over 4000rpm by then, and I'd think the bigger body cars would have higher gear ratios.

At 70, mine would be doing close to 4000, so I'm guessing my car is in 3rd.
11-25-2007 07:17 AM
79Mercy At 70 the motor is humming but I doubt it is 3500 maybe 3000.
11-25-2007 07:17 AM
frans-c That's a real nice looking car ! Please, just do something about those wheel arch trim pieces...

That engine speed looks about right. I have a South African manufactured (i.e. Euro) 230E, and at an indicated 125 km/h (I'm too lazy to do the conversion, sorry), my engine turns over at about 3650 rpm. I own a four speed manual, by the way.
