Need Help Identifying Transfer Case
I have a 2003 Chevrolet Silverado 1500 ext cab Z71 with 5.3 liter, automatic transmission, and automatic transfer case. VIN number is 2GCEK19T231363198 if thats any help. I need to know what my transfer case is and if at all possible what size and gear ratio my rear axle is. Please and thank you!!!

Check your RPO codes in your glovebox...there's a diagram somewhere that shows what each code means. Google 03 z71 RPO codes and you should be able to find em
