Okay will do........Bill did you get my email about me having that lean miss back again? I made an error in judgement and got greedy thinking we could cheat a little more on the lean side.........but not gonna work pal. We gotta get rich again:'(
It's hard to believe an adjustment that minor can produce such a noticeable increase in power and fuel economy.......too bad the engine didn't like it :confused:

Yep... working on it tomorrow and will get it resolved. :thumbsup:

Cool.......my apologies again for the mistake!

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 :shrug: 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.

I had something happen today I hadn't noticed before. I was experimenting and advanced shift firmness to 5,8, and 8. After this all was smooth until I went up a small rise. The gear PID showed the TC stayed locked until I came over the top to a slight decline, then it jumped in and out of lock a few times until it settled down. This happened again a couple of other times even after I set the firmness back down. I had the cruise set at 65mph and when I increased it a couple of mph it seemed to help. Would changing the TC lock or unlock points correct this or do I just need to pay attention to the cruise setting.

I don't think it has anything to do with shift firmness, Dfish. I bet it's because you had the cruise control set, which lets up on the throttle as you start down the incline. If the converter is locked and you release the throttle, it will unlock and, Bill explained that was a feature Ford put in to increase your fuel economy. (The engine/transmission doesn't drag in coast). Now, I'm guessing that the small decline wasn't really enough to keep the throttle at the "let off" point that caused the unlock, so, it locked back up again. But that wasn't stable either, so it unlocked/locked....

Possibly, if you reduced the lock and unlock speeds for each upshift/downshift, it might "tame" this behavior a bit.
