    Default How to tell what gears you have?

    This is dumb, and I should know this but I can't remember what gear ratio I have on my truck. I can't find the sticker which says it, but ive seen 2 possible gears in the manual, and I've looked online and it shows a different gear ratio so.. I guess what I'm asking is -- Is there anywhere on the truck I can look to find out what gears I have. It's completely stock so. The three gears i've seen are 3:42, 3:73, and 4:10. Online it says SLT models have 4:10 gears? But i sort of doubt that? It sounds like I should have 3:42 or 3:73.

    Oh and the truck is the one in the picture, 2005 GMC Sierra 1500 SLT Z71 Ext Cab

    Anyone who can help, let me know. Thanks!
    Brandon
