Probable cause:
- Open or closed circuit condition,
- Poor electrical connection,
- Failed 4WD low switch

Hope this helps.

You might try another mechanic if this one can't get it fixed. Shaking is usually caused by one or more cylinders mis-firing for whatever reason--usually faulty ignition or fuel injection. Has the engine had recent tune-up? Bad spark plugs/plug wiring are frequent villains. Not sure what an 'OS2' code is. Hope this helps!

YOU HAVE TO SEE WHAT TROUBLE CODE YOUR PCM IS TRYING TO GIVE YOU.GO TO ANY AUTO ZONE THEY WILL DO IT FREE.CHECK ENGINE LIGHT IS NOT GOING TO TURN OFF UNTIL YOU FIX THE PROBLEM.

did you check your transmission fluid

I was browsing unsolved problems. If you still have the problem, I'll try to help you. But it's going to be awhile trying to communicate back and forth. First...Check the engine for spark. Take off a plug wire and stick a screw driver in the wire end and place the metal part of the screw driver next to something on the van that's metal. Have someone crank it over for just a second or two and see if a small spark jumps from the screw driver to the metal part. I'll check back for your answer.

I have the same problem with my 98 mpv when I flip the switch the light just flash's
