Remove the floor pan in the middle of your cab. The tranny lever comes up thru it. It has large flat head sheetmetal screws holding it down. There is a square sponge sealaround the top of the shift tower that will need to be replaced. the vendors have it. After you remove the floor pan(I'm havibg a brain fade, don't remember the proper name) You will see a small square head pipe plug towards the back on the passenger side. thats where the oil goes. I think you will see it quite easily after you remove the floor plan. Since you are loacl to KC, if you get stuck, give me a buzz. 816.985.2860
