My supervisor at work has a 6 speed auto behind a 6.0 In a 07 chevy, and it has held up very well in the mine that I work at..which most auto tranny's have alot of problems in the rocks and the up and down the hills...... i replace alot of them... It's really nice though, I pull trailers with it quite often, and it is probably my favorite truck to drive(when I can get him out of it.......

I have one for my company truck... Its a nice riding rig. Very comfortable.

Only thoughts is, replaced both headlights already. New steering box. Nice thing the headlights went bad. Would have never known... Got aa hot drip in the face while replacing bulbs. Just think, yelled at my duaghter for dripping oil in driveway with her Jap trap. It was me, ha...

Had to flush tranny twice. I do alot of heavy hualing. Only complaint with towing is you feel it back there. Had factory shocks off at 25500 miles. I put about 750 miles a week sometimes or more. I do like the rear door feature, they swing all the way open.

All in all i enjoy driving it. Its surely got alot of power running open roads.
