Here's the deal. I'll start my truck, step on the brake, and put it into drive. I start off without pushing the pedal and start almost coasting until I step onto the gas. Once in a while my transmission it seems goes up a gear and you start hearing a grinding sound. I put it into neutral and it goes away... What gives?
