Had to have Tranny re-built.

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.
