Bought a Gryphon

Jack, I am going to post this on f150online aswell but wanted to get your opinion and anyone else that wants to chime in.
One of the main reasons that I got this programmer was the fact that my tranny was slipping. At about 30mph or so foot off the pedal coasting, I would give gas to pick up with traffic or start back up a hill, the engine would idle up as if it was in neutral and then drop into gear. This seems to have been taken care of with the tuner and the canned tunes on it. Last night when I was trying out my new toy I noticed that problem was gone. After I made the turn and started heading back to the house I throttled it pretty hard and was holding thru the gears. I believe going into 3rd it slipped, idled up then dropped into gear.

I am thinking this might be an issue with the tranny still since this happened.
Any thoughts would be appericiated.

There COULD be a problem in your transmission. One of the things that a tune does is to reduce the time lag between clutch engagement and release during shifts. The tune also increases line pressure and reduces the torque reduction "dive" that Ford engineers into things.

So, you COULD have excessive belt slip which may be a sign of worn belts. But, you might also try increasing the shift "firmness" a bit. I wouldn't make a huge change here though. Since the slip was only felt 3-4, try changing that to a +3 setting?

You have not said how old your truck is, and I don't know how long it's been since you've had the transmission serviced. I'm not sensing that your driving style is particularly "aggressive" though. And, I'm sensing that normal, part throttle shifts feel fine?

I'll change to a +3 and let you know. As for the age it is an 07 5.4 XLT 98,000 miles and your right about my driving. Not real aggressive.

Just curious, If I was going to have the transmission rebuilt, maybe stronger kit in it, I would have to have Bill change the tunes?
Also, I had the tranny serviced about 2months ago. This was the first thing I thought of when it started slipping. I am doing some work at a high school
now and they have a auto shop. The whole thing only cost me 50 bucks due to it being considered training.

As long as the pcm does not get reflash with a different calibration Bill should not have to rewrite your tunes.....

But.....here's the catch.

If you rebuild the tranny and put in a performance valve body and find the shifts to be too harsh then Bill will/ should make adjustments......

YEAH! After the buy and spending the money to have the doorstop unlocked. I ordered and received my new tunes. Very happy!

On a different note: I am now running 87 performance. I got used to the canned tow tune as far as the shifting. Also I did notice yesterday that I did have a little slip from 2 to 3. I know that I might have an issue with my tranny but didn't have any slipping on the canned tow tune. What should I change the shift firmness to with the performance tune to get that solid shift feel again and would have any negative affects on my tranny??
Thanks

You can increase the shift firmness in the 2-3 shift. As long as you don't go overboard, there should be no harmful effects. Try increasing it by +4 and see how it feels. If it still feels "slippy", increase to +8. I would not go above +12. It may be that there is an in-between setting that would be ideal.

The shifts should be positive, but in the immortal words of our great sage Longshot270, "They should not feel like a kid behind you is kicking your seatback."

If you find what you like, you can have PHP "write" it into your tune, so you would not have to mess with it.

Thanks Jack. I apperciate the follow up. I'll find one I like and give feed back.
