Just return from a 500 mi. trip that took me over 8000' in elev. I lost TCC lock up above appox. 5700'. Tranny would not lockup even on level road when the engine was loafing. I can only relate it to the altitude. I am thinking MAF or air temp sensors are causing this. Any ideas? (92' Explorer 4x4)
