I bought some new gear oil for my transmission and I got out the FSM to see which is the fill bolt and I don't think the transmission picture matches my truck. The FSM picture shows it on the passenger side about half way up and in line with the drain plug. I don't have a bolt there, the only one seems to be at the very top. The drivers side does have a lot of bolts though. Does anyone have a picture they could put up that shows the fill plug? Thanks.

 

It's on the drivers side in the middle

 

The drain plug is on the drivers side - furthest forward 17mm plug. It should look identical to the t-case drain plug located on the rear of the t-case.

 

I figured it out yesterday morning. The fill plug on the tranny looks just like the drain plug on my oil pan.
