    Just changed the fluid in my 06 hummer with no problems. You have to use Dexron 6 fluid only and when you replace the filter you also need to change the filter inlet seal with a new one. Came with the Fram filter.

    My 2006 H3 broke failed a couple of days ago due to the shifter cable disconnection. I got it towed to the dealership and when they finally looked at the vehicle, they said that the drive shafts needs replacing also. Apparently the grease leaked and the shafts were all worn out. I did not notice any "shuddering", "excessive noise", or any problems whatsoever prior. It was also at the same dealership less than a month ago for a complete maintenance service, ie: oil change, tire rotation, etc. plus the transmission got serviced also. I'm wondering what would cause the shafts to fail without any indication. Can the towing damage the shafts?
    Will appreciate any input. I am looking at more than $2K to get it fixed.

    I have an H3 2007 model....with 57k miles. I am about to have the 50k service done tomorrow...

    However, a couple of days ago...I was driving down the highway and it acted like it went into neutral...pulled over on the side of the road...it did not operate by moving forward either into drive, drive 3, drive 2 or drive 1...we put it in park....and we heard grinding noises...I thought for sure that it was toast...put it into 4wheel high lock and it was drivable...took us to the next exit. Got out to check everything (engine off) fluids were fine. Started it back up, put it in drive (4 wheel drive only) heard a slight whinding noise....but it has drove fine...for the last few days...what did you do to correct this problem? Did it correct itself, like it did with mine....

    PS...have noticed it slip from drive prior to this incident...however acceleration was restored within a few seconds
