Well Bill my tranny seems to be hunting a bit more lately. It still only seems to happen when I am in second gear, it changes about 400-600rpm.

Have you set it back to stock yet and tried that to make sure it the tune?

I Guess this is a custom tune that it is doing it on? rather than the canned.

Sounds like the TC is unlocking and locking? Could you change the display to monitor "Comm Gear" and verify this? The TC is locked when you see a padlock symbol.
