How often should I change my transmission fluid? And any other fluids for that matter?

What year is your truck? I believe it was in 2005 Toyota switched to the WS (World Standard) transmission fluid. It's supposed to be a lifetime fluid and doesn't require changing.

In my Camry, it uses T-IV transmission fluid and the dipstick says the fluid doesn't need to be changed under normal operating conditions. It should be changed in severe conditions.
