first oil change and this what came back to me

Which stealership did you take it to?

 

i took mine to jiffy lube and they actually showed me the chocolate that was on my rear diff. my truck has 22000 and the stealer did the 15k service. also, the cabin air filter was trashed. so, i say change trans fluid and inspect rear diff.

 

yeah he said mine was black and that it had never been changed

 

JiffyLube???? They probably put used oil in it.
Take it to a Taco dealership or at least a good certified mech. I think that would be the first place to start. Then have your Taco dealer get you a manual.

i was there when he put it in...the guy even called me out to show me the fluid and when he leveled it the clear fluid drained so i know there is good oil in it... i know there are some jiffy lubes that work like shit but i think this is one of the good ones... usually i do all my fluid changes myself but these past months i just haven't had time...
