Just got my H2 back from the dealership for a few things including tans slip 2-3 shift. Rebuilt tranny and stated the Reaction Carrier had come apart. Had to rebuild tranny and replace input and reverse housings, reaction carrier, reaction shell, plus clutches, seals and god knows what else... Sounds like a major rebuild.... All was covered under warranty but this thing has never been in 4wd or off road (soon to be remedied)SP and only has 16,000 miles Don't get me wrong the dealership took great care of us and the H2 just too early for a rebuild...
Also had a new Air compressor with new left and right high pressure lines due to Svce Air Suspension on the DIC multiple times.
And... Right lower ball joint was LOOSE!!!! causing a clank during turning Glad they found that.
Any one else had simular issues... Still love the H2 though
