greatkid: good advice and helpful post buddy..even i think this will be a minor issue with solenoids or even a dirty clogged filter..

zackm: i hope you at least feel good after your weird comment..amazing how many things you assume about the owner w/out ever meeting him..and the owner said NOTHING about his coolant and ATF mixing so quit the 'know-it-all' vibes..oh and the Hummer isn't a high end car either so there..
