How long have you owned this car? It's pretty normal for the first shift and to a lesser degree the second one to shift rather abruptly. If it's neck snapping harsh, you should have it checked. It can be adjusted.

There's a vacum modulator on the side of the transmission that you turn to either soften or stiffen the shifting characteristics.

Do a search function. There is a lot of info in the archives.

But Mr. Bill is right. 1992 is the first year of first gear start. 1991 and older 300E's start out in second gear. The 1 to 2 shift is a little abrupt.

I concur with the adjustment for the vacuum modulator. Also make sure to clean out your vacuum line from the modulator to the manifold.

2nd gear start, from what I've heard is for both fuel economy and smooth takeoff under light pedal pressure.

It was the vac. modulator. Turned c/clockwise, solved problem. Thank you all very very much.

My 1994 E420 with 65,000 miles shifts firmly from 1st to 2nd gear about 80% of the time. The MB Dealer did a trans service last November at 52,900 miles (overdue 45,000 service) when they took the car in on trade. Another trans service was done in June at 63,000 miles (over due 60,000 mile service, but only 8 months and 10,000 miles since the previous one). I paid $100 extra for "special" trans fluid on this last service. Still shifts hard enough from 1st to 2nd to make the plastic trim on the A, B, and/or C pillars squeak during the shift.

Which side of the transmission is the vac. modulator on? What other culprits should I be investigating?

Not to be matter of fact, but..

1st gear 300E starts began in at least 1991, as mine has the feature. I love it, and even though I know my MPG suffers, I couldn't imagine starting off the line in a sluggish 2nd. Gotta love the whir of the 103, even at 232k miles!
