OUR 2003 E320 WAGON STARTED HAVING SHIFTER PROBLEMS TWO DAYS AGO. IT WILL NOT SHIFT PAST NEUTRAL TO PARK WITH THE ENGINE RUNNING. IF YOU GO INTO REVERSE IT DOES NOT WANT TO SHIFT TO DRIVE IF YOU PPUT IT IN PARK IT STICKS IN PARK UNTIL YOU TURN OFF THE CAR. THE CHECK ENGINE LIGHT IS ON. I AM ASSUMINGIT IS SOME TYPE OF SENSOR ON THE TRANS. THANKS

When you said "it wouldn't start" did it turn over (starter cranking the engine) or did it act like the battery was dead and wouldn't crank, even though all the dash lights lit up?
If it simply didn't crank over but then by you shifting it out of park, then back into park, may indicate a park/neutral switch problem.
It may have been something as simple as the shifter, when the vehicle was last parked, didn't fully engage the park/neutral switch into the park position. BUT by you moving the shifter out and back into park it engaged the switch.
Cold weather can do some strange things sometimes when it comes to mechanical devices. IF it acts up again, simply try the "trick" that worked the last time.
It may just be temperature related and may not give any more problems once the weather warms up.
sounds like you may have a bad safety switch on your shifter, if you have intermittent problems with it starting and it changes with movement of the shifter, it's probably the safety switch. The next time it doesn't start, shift to neutral and try it, if it starts, its the switch. The switch is designed to keep the engine from starting if it's in gear, but it will let you start in neutral and park.
Is there any warning lights or malfunction besides this?? There are three main parts that may cause this: Park/Neutral safety switch(located on the transmission), Brake pedal switch(located at the brake pedal), Shift lock solenoid(located below the shifter). P/N safety switch prevents the shifter from shifting out of (P) or shifting into (R/P) while vehicle is in motion. Brake pedal switch sends a signal to release the shifter lock to shift out of park. Shift lock, locks the shifter as describe above and is located at the shifter base. I recommend inspection/replacement of the shift lock solenoid and P/N safety switch as its an intermitted problem. Hopefully this helps
assuming u do always press on brake pedal before shifting out of park,on passinger side of shifter theres a little cover beside shifter u can take off and insert screw driver in,it will bypass lock mechanism!
