Had to have Tranny re-built.

[F150 Man 4Eva]

Hello all...well things were going just great with my truck, and the custom tunes on my Gryphon, untill weekend before last. My truck was not wanting to shift into 4th (originally), then 3rd and 4th, and then it went out completely. I returned my truck to stock, removed the Gryphon, and had it towed in to the dealer. It took right at a week, but I have my truck back now. They say that the clutch went out. Seems to drive fine now. But I noticed that all my info. on the dash was reset, as if my battery was disconnected. Should I be concerned that the dealer may have reflashed the PCM? I have not attempted to reinstall the Gryphon yet, but I would like to asap. Just wondering if there are any precautions I should take, or anything I need to be aware of. Thanks, Travis

Since you have custom tunes you'll get an error once you plug it in if the hex code has been changed.
But......
Nothing will be hurt, Bill will just have to rewrite your custom tunes.
And......
I don't know if they'll charge for the rewritten tunes.

Well there is definitely a problem. I went to hook my Gryphon back up, and immediately, it said something about not recognizing my ECM...I tried anyway....then got these messages about no communication and needing calibration. And then DTC ALERT: 4 ........... All kinds of codes thrown...so I am just assuming that they reflashed my pcm?.?.?

It sounds very much like they flashed your PCM. Probably had to if they rebuilt/replaced your transmission. And, don't worry about the codes - yet.

Bring your Gryphon to your PC, fire up Pegasus and connect the Gryphon. Once it reports it is connected, click on [Updates]->[Gryphon Update Manager]. This will show the firmware and calibration updates that are available. You want to install BOTH. This will return your Grypohon to a "canned" status, and it should recognize your truck's PCM now.

With the ignition key ON, plug it back in and note the HEX code. If it's different than the one in your User Profile, you've been flashed. To get your custom tunes back, Bill will have to rewrite them for the new hex strategy. But, you can run your truck on the canned tunes while you're waiting.

If the hex code is the same though, try downloading your custom tunes again: [Updates]->[Custom File Download] or [Updates]->[Download Targeted Functions], depending on your version of Pegasus, and try them again.

And, I would expect a few codes if a lot of work was done. The truck has to relearn a lot of things.

Hey, THANKS A LOT! I am going to try your suggestions RIGHT NOW!... Let you know how things work out. THANKS again!

[F150 Man 4Eva]

It worked! And boy am I glad! I guess I was taking the Gryphon for granted. Because I forgot just how much of a DOG my truck is WITHOUT it. The other day, I went to pass a car, and when I hit the pedal it just boggggeeddd. Now... it is like night and day. Sooooooooo glad it all worked out. Now hopefully this tranny fix will hold up! Thanks again!!

Don't forget, you can run the canned tunes now. I'd suggest you use the Level 2 tow tune (even if you're not towing). You'll get much improved transmission behavior and more low end power.

Oh I got the customs back. The Hex was the same. So I did like you said, and reloaded them on the Gryphon...hooked it back up and...presto...no problems!

[Jackpine]

OK, good to hear! I wonder what caused the earlier problem?

Do you think that it could have been me plugging in the Gryphon to the truck, before I turned the key on??
