Hey I just recently bought my girlfriends sisters old car from her. It is a 1998 grand prix se with the 3100. In my opinion i pretty much stole it from her for 500 bucks but she just wanted to get rid of it.

Anyway how do i tell what tranny this car has in it? Is it the 4t60e? I need to do a tranny service bad and want to buy a shift kit and install it at the same time.

Also I did a shift kit in my Camaro with a 4l60e, does anyone know how much more difficult it is to put one in a grand prix.

Thanks,

Michael
