It's pretty straight forward to install one. Here is the write up to look over http://www.grandprixforums.net/shift_kit.php. You could also do the DIY shift kit if you don't want to spend the money on one of the existing kits. I am using a wbody store one that I put in at 50K miles. 36K miles later the car runs good. I will be changing the fluid again and will be going with a transgo kit.
