1995 Chevy Truck V8 Four Wheel Drive Automatic 116000 miles
I have a 95 chevy that while going up a hill or mountain pass it will down shift and seems lo lose. The motor does not stumble and electrical systems do not quit but it just doesn't want to climb the hills. This is problem is occuring while it down shifts from over drive to drive and then it just slows. It usually holds out around thirty five or so. The check engine light also comes on but once I hit the top of the hill it goes off.
