Shifter on 2004 SL500 gets stuck in Park, able to shift eventually and once out of park can shift from drive to reverse - on downhill shift lock is more pronounced and more difficult to remedy.
96 S500. Failed emission test. Changed the O2 sensor, however, mechanic said I need to drive the cay 100 miles for the system to reset. I did and went back for retesting, mechanic said the car is still not ready and I need to drive the car for a few more days. How long does this take? and is there a way to manually getting the system to sync?

Thanks much!
