I know you said there is no check engine light but I'd still get it scanned for OBDII codes.

There's some sensors that will trigger that light. Speed sensor and stop light sensor come to mind. The speed sensor will probably cause erratic shifting or trigger limp mode. Try and disconnect the battery and see if the sensor resets itself (if thats the problem).

Because there's no CEL, I'd bet on a transmission sensor /speed sensor related problem. You won't be able to diagnose those with an OBD2 scanner.

If you've checked the transmission fluid level, have a happy CEL free engine, the next thing to check would be the transmission conductor plate and the speed sensor at the rear differential.

Here's a link to the 210 board detailing how to replace the conductor plate. It's for the 5G-TRONIC transmission (which you should have with a 1997)

http://www.benzworld.org/forums/w210...ml#post3538903

There's a PDF to download that has a step by step DIY (including symptoms leading up to replacement).
