Welcome to DF. Will move you to the correct spot.

Oil fill cap is on drivers side valve cover, at the front.

If your speedo isn't working, check the wiring to the VSS that is on the tailshaft of the trans, or t-case. Depends on whether you are two, or four wheel drive. (you obviously won't have the sensor on the t-case, if you don't HAVE a t-case. )

 

Or the speed sensor on top of the differential.

 

On the 97 and older trucks, the speedo is driven from the VSS in the trans. 98 and up that one went away.
