I checked the archives and it appears that I am not alone in my problem.
Under hard acceleration in second gear, rarely it will pop out of second with a loud BANG. (and of course the engine will then rev to 50,000 rpm)
Is there any update on solutions? I just had my first oil change done at 9000 miles but I forgot to mention it. It happened 5 days later.
It sure does sound terrible, but I can't replicate it and everything seems to be working OK.
