Maybe it is a vacuum problem? dunno...I'
ll drive it until it needs more attention.
You have a problem of thick ATF or a failing conductor plate. A conductor plate is basically a wiring harness but laid flat - but has 2 speed sensors built in.

The shift solenoids have little screens that sometimes can get dirty but an ATF change helps in these cases as the trans is pretty cleverly designed. All debris etc fall into the pan rather than getting stuck.

My 97 has done this right after a starting the engine. It happened 4 times in ~100 engine starts since I've had the car. It seems to not want to shift out of first gear no matter how lightly i feather the accelerator pedal until it hits 2500rpm then BANG next gear and its fine after that for another week.

Last time I noticed that it wasn't upshifting but BEFORE it banged into next gear I came to a complete stop, shift to P then shifted back to D. Perfectly normal shifting after that without ever banging into the next gear. Give it a try.

My '99 E300D turbo had a couple odd shifts and had some flaring 1-2 regardless of mode.
I took it to my friend and excellent mechanic who has vastly more knowledge than I. He spotted a leak on the connector to the transmission and noticed it was the old style, which had been upgraded by the factory. He ordered the new connector and replaced gaskets and I supplied OE fluid of the correct type also noted it has a drain plug on the torque converter, now its fixed and shifts properly 1-2 no flaring!
Also the computer readout was flaky the first time he hooked it up and following the new connector it was solid.
Incidentally look for any signs of a coke or coffee having been spilt into the shift gate on the console, mine was not one of those death spirals that have been described as a result of liquids getting into the circuit board that is located just under there, its a bad design as its not sealed well.

Awesome car, I love the '99 turbodiesel! I hope you get yours fixed properly.

I took liberty of highlighting the words COMPLETE STOP in tjts1's text because I was told, when I was getting an education from someone more knowledgeable than myself on these electronic trannies, that a guaranteed way to crap up your transmission in these babies was to shift gears while the car was moving, even if barely rolling that's enough to cost you thousands...it places a tremendous force on internal parts that give up and go bye-bye!

Thanks Zulfigar! I will look into that wiring plate you discussed!.. I have been changin out the ATF on this 'sealed for life' transmission regulalry at about 60,000 miles. I too, come to a complete stop after it won't shift into 2nd or 3rd and just let things calm down.
