Hello and thank you. I tried looking for my problem, but finally just asking.

Truck has been well maintained, worst issue is lots of wiring degradation, fluids have always been maintained but recently all of a sudden, the truck would no longer shift into drive. It goes into reverse perfectly and will drive in reverse but will not go into any forward gears. No other problems or work recently done besides new radiator hoses and an oil change. I had the transmission fluid flushed and changed last summer. Any direction or advice would be much appreciated as this is my main work truck, I use to feed my family.

I have seen the transmission fluid temperature sensor go out causing this issue. But to be sure we should run the codes. If this is an OBD2 system this guide will help:

Here is the fluid temperature sensor in case you want to try it. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
