Good to see you back up here Jordan!
Please do what Lars suggested. Your Hex code may be the source of your problems and, if so, Bill might have a quick fix.
It DOES sound like a TC problem, especially the way you explain it now and I don't think there's any way this will cause damage.
You might try going into Custom Options and changing the TC lock and unlock values by -10 for 4th gear. It won't hurt anything, even if it isn't right. What I'm trying to do is to suppress the tendency of the TC to unlock (then lock back up) while you're at cruise.
