Question about 2003 Mercedes-Benz E-Class
When going at low speeds, gears change ok from 1, 2 and 3. However there is a slight vibration between 2nd and 3rd ... as if the car can't decide which gear to change to . This happens in traffic ( +_ 30 to 40 KM /h ). To alleviate this I have to press more aggressively on the eccelerator to stop the vibration . This forces the car to change to a lover gear with no vibration (result = higher fuel usage ). When I take off and drive to max permissible speed all gears select normally . No vibration .
Thanks for the help ..
These cars usually have a two piece drive shaft. There is a center bearing in the middle of the driveshaft for support and dampen vibration. It could also be the front rubber coupling where the transmission tailshaft and driveshaft meet. If both are fine try loosening the bolts on the rear transmission mount. Your mounts may be out of alignment allowing for unusual angles between the transmission and driveshaft. Good luck.

Sounds like a shift solenoid where the transmission control can not decide where to go
