03 CTS transmission problem?
 

Hey everyone,
I am new to the site but I have been reading over the forums ever since I got my car last year. This site has been a great help to all my problems I have had up to this point. I have searched the site but have found nothing so far. I need help.

About 2 weeks ago, I noticed when I put my car into gear it just revs for a second and then will start moving. I have-not had time to get this check, but then last night I slowed down to go over a speed bump and went to lightly press the gas and all my car will do now is rev. It wouldn't drive at all. So i shut my car off, and it drove fine for about five minutes and then did the same thing. Its like my car thinks its in natural when it really is in drive.

I have looked every where for an answer and can not seem to figure it out. Please help

Thanks,
Steven
