On hiway going 60 my Nissan Sentra suddenly started losing power and temp gauge went to hot. Was going up a long hill. Was told that it was transmission issue and car was stuck in 2nd gear. Possible?
Most newer cars will enter a "limp mode" when the computer detects the engine is overheating. Power is reduced and the computer begins firing alternate cylinders. This helps dissipate heat by using the engine as kind of an air pump. Most likely the cooling system was working beyond capacity going up that long hill. Especially if you had a fully loaded car and/or were towing a trailer. Once the engine cools off things should return to normal. Check the coolant level and make sure it's full. HTH. -Jim
