Ok, I changed the ECT Sensor and it did not fix the problem. The O/D off light still comes on after about 20 minutes of driving and it seems the torque converter isn't locking up. Also my electronic 4X4, windshield wipers and dome light doesn't work. I checked the fuses and all are ok. Could this all be tied to a relay? If so, which one?I had the truck checked at the dealership today and found out that the 1st and 2nd stage valve body is going bad. It will cost
$1100.00 to replace the unit. Also they said the GEM sensor is bad. another 600.00. What's a guy to do?
