When the engine is cold or even if it has warmed up 10 minutes or so in the driveway when driving on the highway the transaxle will not shift into overdrive. However, when driving @ slower speeds 40mph and the engine heats up the transaxle will shift into overdrive. Its like if the engine and transaxle has time to heat soak the transaxle will shift into overdrive. But taking off from home to work on the highway the engine after a few miles heats up to operating temp, but never will shift into overdrive. Just recently installed a new thermostat, egr valve. I put card board in front of the radiator trying to get the engine to heat up a little hotter and it seems to make no difference. As I said if I have driven the car for a few miles and if I set @ a long red light it will shift into overdrive. Sometimes when it has shifted into overdrive when driving on the highway @ highway speeds and the engine seems to cool down slightly the transaxle will down shift all by itself. ?
