99 grand am se transmission

Hello, well im basically running a 99 grand am se. Its an automatic and the transmission is just now begining to go. I was wondering if any one knew any good sites or manufactures that make aftermarket racing transmissions for grand ams? I love to race my grand am, and dont want another stock transmission sooo, yea, any help would be apreciated! btw, dont tell me to get a manual, its not happening(staying with what i have now).

check out level ten. www.levelten.com they dont have any listing for the grand am but maybe you could email and ask if they have parts for them. good luck

How is your tranny acting wierd?
