Default Limited slip?

I have to change my rear diff fluid. I know there's a limited slip additive needed if you have an LSD, but how do I know if I have one or not. I know I have the 3.55's but I'm not sure if its limited slip or not.
Thanks!

If you have an '09 and 3.55s, you don't have a limited slip. A limited slip wasn't available on with 3.55s until later years.

The 3.55 is an open diff an doesn't require any additive. Use 75W-140 GL5 Full Synthetic Gear Lubricant and top it up to a little below the fill hole.
