I haven't had this issue, but with other automatic cards that I've owned, that's a good indicator that the fluid is low. Of course, you can't check the tranny fluid level in the Crossfire. Have you noticed any leak? A common problem with our transmissions is the seal where some sensor plugs in goes bad, and it leaks. There's a TSB on it, and should be under warranty. I've already had mine fixed. I wouldn't have noticed the leak - it's very slow - except that I had my car in storage, and it had a puddle under it when I got it out.
