HELLO..MY WIFE DRIVES OUR 99 ML32O AND IT HAS 101K ONTHE CLOCK. iT HAD BEEN PARKED UP FOR ABOUT 4 WEEKS WHEN THIS PROBLEM AROSE. WHEN TAKING OFF THE GEARBOX WILL ONLY CHANGE UP TO 2ND GEAR AND WILL HIT THE LIMITER. I HAVE TRIED BRAKING AND THEN ACCELLERATING HARD TO TRY AND GET IT THE GEARBOX TO CHANGE UP BUT TO NO AVAIL. THEN IF I STOP AND TURN THE IGNITION OFF AND ON AND PULL AWY IT WILL GO UP THROUGH THE GEARS BUT NOT AS SMOOTHLY AS BEFORE..PLEASE HELP...?????!!! COULD IT BE JUST A MATTER OF CHANGING THE GEARBOX OIL ????
