2010 Transmission

[yzflier977]

I am new to this forum so please excuse the topic if it's already been covered elsewhere. I did a search, but didn't find what I was looking for. So I have a 2010 Sierra SLT crew cab with the 5.3 with 129,000 miles on it already. My question is where in the codes in the glove box do I fond which transmission I have in the truck? I'd like to know because I want to see if there's any self rebuild kits out there. Thanks in advance for the input.
