I'm looking to upgrade my TV and have two trucks that are the same expect the trans. & diff. in mind. one is a 2009 Chev with 5.3, 4 speed trans. 3:73 diff. the other is a 2010 Chev with 5.3, 6 spee...
OK, the 2010 TV, I was looking at sold before I could act. Anyway I found another 2013 that I like and is equipment the way I like. However a member on here said that I need RPO Z82. this truck Has RPO Z85. what is the difference, and does it matter? Thanks for your comments. John
