How can I figure out what trany and gears I have because I am thinking of buying a shift kit?? Ireally need to find out soon

 

Inside the driver's door frame is a sticker with a lot of info. One piece of info is labeled "TRANS." Under this is either a "U" or an "E.", assuming you have an automatic. The "E" is either E4OD or 4R100, depending on year. The "U" is the 4R70W, or AODE, or AOD, depending on year.
