Yesterday, my wife’s 02 Tahoe (w/167,00 miles on it) had an issue, and from what she is telling me this has happened a few times over the last couple of months.

When leaving from a stopped position (traffic light), she pressed the accelerator and the truck did not move, she let off the accelerator and then pressed it again a little harder and the truck moves on down the rode like nothing was wrong. This has only happened a couple of times in the last few months, most times it leaves from a stop just as it should.

Note: I just replaced the rear brake pads, which were way over due. Could the pads be sticking?

I took the truck for the ride and it shifts from gear to gear very smooth, the transmission fluid is a little low, maybe half a quart, and a nice pinky orange color. ATF fluid and filter changed at about 95,000 miles.

Could this be a transmission issue? I need a little help diagnosing this; I don’t know where to begin.
