I HAVE TWO 2006 H3 HUMMERS BOTH WITH THE 5 SPEED MANUAL TRANSMISSION. UPON ACCELERATION FROM A STOPPED POSITION IN FIRST GEAR, DEPRESSING THE CLUTCH FOR THE SHIFT INTO 2ND GEAR THE ENGINE RPMS REVS TO ABOUT 4000 AND STAYS THERE. SHIFTING INTO 2ND GEAR & RELEASING THE CLUTCH THE RPMS DROP BACK DOWN. ACCELERATING TO ABOUT 3000-3500 RPMS, DEPRESSING THE CLUTCH, AGAIN THE RPMS CLIMB TO AROUND 4000 AND STAYS THERE. THE SAME THING OCCURS DURING UP SHIFTS ... THIS HAS HAPPENED NO LESS THAN 7 TIMES ON ONE H3 AND 5 TIMES ON THE OTHER H3. THE HUMMER…

TL*THE CONTACT OWNS A 2006 HUMMER H3. ON MAY 23, 2008, WHILE DRIVING 35 MPH, THE CONTACT ATTEMPTED TO DOWNSHIFT AND NOTICED THAT THE TRANSMISSION MADE A RUBBLING SOUND.

MY H3 HAS BEEN HAVING ISSUES WITH RANDOM WARNING LIGHTS APPEARING. OFTEN MULTIPLE LIGHTS LIKE ENGINE, CHECK TRANSMISSION AND TRACTION. EACH TIME I WOULD TAKE IT TO MECHANIC AND WOULD NOT FIND A PROBLEM ANYTHING IN ENGINE. THEN THE 4 WHEEL LIGHT DRIVE WOULD NOT ILLUMINATE. THE MOST RECENT PROBLEM IS MUCH WORST... WHILE THE CAR WAS NOT RUNNING THE RIGHT TURN SIGNAL CAME ON BY ITSELF. I GOT IN IT TO DRIVE IT TO LOCAL MECHANIC AND WHILE DRIVING IT ACTIVATED THE BRAKE AND MANY WARNING LIGHTS WERE FLASHING AS WELL. VERY DISTURBING. I HAVE OWNED TH…
