Have you done the spark plug wire TSB Re-routing the wires. Thats all i got.

 

yeah it is only in third when it does it today getting on the freeway i punched it down hard it was fine till it shifted into third.

 

k so today it did it in first. while doing it, it seemed like it wanted to go but it would rev up and bog down repeatedly. i also noticed a weird smells while it was doing this. i dont know the differance in smells when it comes to lean or rich. and then getting on the freeway it went through the gears way to fast and made it hard to get up to speed. this truck is pissing me off!!
