How to check transmission fluid in this truck?

Hello,

The transmission fill plug and the level indicator is located on the passenger side of the vehicle, front portion of the transmission case. You will have to access it from under the vehicle.

I have attached diagrams and the fluid checking procedure below.

Please let me know if you have any questions.
Thank you.
