Once the problem is identified, we can modify the offending parameters to resolve the issues.

Take care.

I have noticed on my PID the only gear I get the "lock" symbol is in 4th. None of the others show it no matter what speed or load. Is this normal?

well after reading this and trying to think about mine...I can only remember seeing it in 4th but I could be wrong

but I am sure someone will have the answer.

If you take your truck out of overdrive (OD), and are running at a constant speed, you should see 3rd gear lock as well. At least that what it does on my 2007 4.6

I generally have OD off, but with that being said I may just have missed it while looking at the display, plus I haven't clocked too many miles since ive had it so. But I definitely would have thought it would lock in 3rd.

I haven't tried this either, but I think it should lock in 3rd with OD off, or in 2nd or 1st if you put the shifter in one of those two slots. To keep it locked though, you have to have a pretty constant throttle deflection. Increasing it or letting up on it is going to unlock it.
