greetings all,we are currently having problem with our 2002 ck2500 hd when driving under normal conditions or towing using tow/haul function in that for no apparent reason either trans disengages our other part of final drive just for a part second the engine (6.6 duramax) over revs then truck drives normaly again without any change in controls.i have run scan11 but no codes display shows.fluid level in trans fine eg external filter change and fluid doesnt appear discoloured or have burnt smell.it doesnt feel like slip but total disengage?any ideas would be appreciated.thanks
