I just took my 6 to the dealer yesterday to have them check out the tranny because it was slipping and banging from first into second gear, almost as if getting hit from behind. A whole day and a half later I went to check up on my 6 and they told me that they couldn't replicate the problem but that they did find that the tranny was having probs with the gear shifts. Now their waiting for tech support to tell them whether the cai has anything to do with the problem in order to proceed and how to proceed. If they say yes I'm screwed. I have just installed the cai 2 weeks ago but I have had this problem before about 2 years ago and they updated the computer and that seemed to help, but occasionally it happened again, it just seemed that when I installed the cai it got worse. What do you guys think? I sweating it out here.
