A couple of newb questions to get me started

Hey fellas,

Looking forward to get my hands dirty in some maintenance but need to know a couple things first that I'm having trouble figuring out.

#1 - How do I know what Tacoma I have? 1GR-FE or 2TR-FE? It's an '07 SR5 Prerunner V6 4x2

#2 - I bought my Tacoma with the TRD package and says it comes with Limited Slip Differential. In the owner's manual it shows a button for that but I have no button. I'm guessing that's only if you have the 4x4 or it's just automatic for mine? And how does this affect my maintenance (i.e. need special fluid or change my rear differential when it says those with limited slip)?

Thanks for the help and I won't be a newb forever

 

Ok, it's the TRD Sport so it just limited slip then. Thanks so much for the help and pictures are always awesome!
