C5 automatic transmission fill plug location?
Hi all,
Does anyone have a picture of the location of the filler plug for the automatic transmission fluid? I replaced my radiator this past weekend and need to top it off. What size socket do I need to open it?
Thanks for your help

About halfway up the side of the transmission pan, driver's side toward the rear.
You're gonna need a lift, or else jack up all four wheels: it has to be level front-to-back or you'll overfill it.

The fill plug is the same as the drain plug (in the pan). The engine has to be running, and the transmission in the specified temperature range when filling.

Thanks for the help! I've got the repair manual that details the filling procedure, but they don't mention what you need to fill the trans. Does anyone know if I can fill it with a snaking funnel, or do I need a pump?

I use a pump myself. I'm sure a funnel and a hose will work too if you have another guy watching when it starts overflow from the trans.
