It should not move in park as that is mechanical setup. Now as far as the other gears, did you drop the transmission pan before you even started the engine? If not you may have pulled any particulate matter off the bottom of the oil pan and hopefully just plugged up the filter, if it got past the filter then there is a very good chance it fouled up the valve body. If you get that all straightened out then service the differentials and the transfer case. Moisture from just sitting can really do a number on gears and bearings especially after sitting that long. You should probably flush all the fluids, brake, coolant, window washer.

Tennisshoes thankx lotz for your quik responce But im afraid i made myself look stupid its supposed to say drive not park. Im going to change filter and fluid, also will flush out lines acd cooler. I am a great diesel mechanic (big rigs) cat, cummins, detroit and mack even have some mercedes benz knowlege but ive never been good with automatics. Again thanx lotz Guido1125


Hopefully that will get it. If not pull out one quart of trans fluid and add a can of TransX and fire it up and just let it idle for 5 minutes then shut down, do that for a few days and see if it helps clean out all the little passages in the valve body. Good luck

Thanx lotz again most helpful words will let you know when ive got it. And what it exactly took to get it right.
