I have a 2001 2wd, GMC Sierra, automatic. The button for the tow/haul option is on the end of shifter. This doesn't work but the Tow / haul option comes on by itself sporadically. The indicator light comes on on the dash and I can feel the truck gear down. Any advice before I take it to a mechanic.

I have a 1997 chevy 3500 vortec 350. It only has 70,000 miles on it, but reverse has went out. It acts the same as if it were in neutral. All else seems ok. I havent had the filter changed since I bought it at 35,000 miles. It has fluid in it, I even put a can of Gunk trans fix in it. I was considering Lucas tranny fix, please help if you got a fix. I was told by the oil change guy that changing the filter may make it go out altogether. Im lost. Any information would be greatly appreciated.

Took my '03 Silverado with 100k to dealer who added a Bar G transmisson flush and suposedly did a fluid exchange. (not what I wanted done) Within 800 miles transmission was fluttering, missing shifts, and failing to shift into 3rd under load. Found transmission over full. Fluid was dark and smelled like cleaner. I had it tested and have the PPM of metals. I also had sample of clean Dextron VI tested for comparison. The results seem very high for tranny fluid with only 800 miles on the fluid. Does anyone have expected range of metals, in PPM, for a transmission with 100k and 1k miles and/or anywhere in between.
