Default 4.7L Throttle Position Sensor

Hey whats up guys. I have noticed lately on my diablo sport trinity that my throttle position is only reaching 60% even though the blade is fully open. It used to be 75%. With that said I am also noticing that my truck is no longer kicking down a gear at 65mph. So I tested the sensor using my DVM. The sensor has 5volts going in. Closed voltage was .38v. Fully open was 3.48v. Does that sound right? I am not experiencing idle issues or anything just the transmission not kicking down at 65mph. Bad sensor maybe? Maybe i was testing wrong. Any ideas?

Thanks
