with my 03" v6, when ii punch it off the line, and it is shifting between 1st and 2nd, some times i lay rubber, it does it quite more when i am shifting it manualy at high rpm, is that normal, or even good for it?.....like when i say it shifts hard i mean it will slightly kick out the back end a bit. do most stock 3.8 auto do that or has someone done something too it?
i have only owned it 5 months....so im not sure what has been done to it.

thanks
