Hey guys,

So my wife was driving her 1999 E300D this evening and the check engine light came on and she stated that the transmission wouldn't shift out of a lower gear.

She pulled over, waited a moment and started the vehicle and the transmission shifted fine.

I think this happened twice..... Of course, I will check the fluid level and I replaced the conductor plate and cleaned the shift solenoid about 18 months ago.

I do not have any type of a Mercedes scanner, only an OBD II.

Any suggestions on what I may check or causes for this symptom?

Thank you all in advance.
