Just for the record, I purchased my Phoenix in October of last year (Invoice #4980). I don't remember my PCM code but I have TNAA4N2 tunes according to my invoice. I have a 2002 CALI 7.3, the cali part seems to be the problem.
Most of my friends have PHP tunes and love their transmission shifting, but I had a friend that also has a '02 cali model, and his trans does the same thing mine does. Driving around town (20-30mph) my trans will constantly shift between 2nd and 3rd gear. Here is a video, it's really hard to tell on the video but you can barely hear it shifting back and forth. I drive in 100 performance most of the time, but it does the same thing in my other tunes. Just wondering if it's my trans problem (it is probably on it's way out, it gets a little warm), or if there is a problem with the tunes.
