Chevrolet Blazer 2004 2 Door, Sunroof, Curved Hatch on rear with Tailgate 195380 miles
It shifts into reverse, but doesn't engage. Also; doesn't shift into overdrive and will not shift down in the OD gear when slowing down. I just replaced the TCC solenoid and changed the filter and also tranny fluid. Still doesn't engage in ? Any clues to what is wrong?
