My Tahoe has about 103,000 miles and lately i've noticed that when traveling at about 7 or 8 mph (usually in a parking lot), I hear like a grinding noise, like gears rubbing, but only at that speed. Plus I only hear it after i've driven for a while, not when I first start driving.
I thought it might be the transmission, but I checked the ATF and it looks/smells fine plus I feel no hesitation during gearshifts.
What could it be?
have the same problem?
