GMC Sierra 1500 QuestionsRefine by vehicle
4.3 - Ever since i replaced my heater core the truck has been hard to start - kills the battery - let it sit for 4 hours or more and if fires right up- drive up the street and back - park it - go back to leave again and it will not start - also, once i get it started i will just let it run in the driveway and after 5 to 10 min it just dies -i have changed plugs, wires, ignitor assembly - I did a fuel pressure test and it read about 56 psi
My truck starts just fine it will shake a decent amount while in neutral, when it shifts gears(automatic transmission) it will shift really bad like it doesn't want to almost like its slipping, when changing from drive to reverse as well it will start shaking more i think due to the lower speeds. No other obvious things to look at though.
I have an annoying lower dash rattle, I believe its coming from the panel below the steering wheel Is this easy to take off?
Or dealer assist on repairs.

From Day one (8/15/05) my Selector switch has given me problems. 2 switches, software update, TCCM replacement (warranty finally) and now I'm being told that my transfer case needs to be completely replaced!!! I'm done! This has been the only consistent issue with this truck and GM will not acknowledge the issue. HD's and Diesels do not have this issue, I have asked anyone and everyone who i see that has this style of truck. Looks on the Silverado 1500 page with this issue and its crazy!!!

Vermin entered the heater ducts over the winter and died there. How much will it take to disassemble the heating ducts to get them out? Is there danger of compromising the air bags with this repair?
It will run ok on flat land. It seems to shift ok when in town. But if you throttle it to pass or climb hill, it falls and acts like it is braking and downshifts.
