My Catera is showing leaking tranny fluid around the pan. I've just looked from the side and not got underneath yet but would like to add and check the level. The owner's manual says to take it to a Catera service center.

I've been doing my own service on my cars since 1970 and although I can't find a dipstick I know there must be a way to add tranny fluid. Probably need a new gasket and filter to but want to add tranny fluid as I felt it slip today. Any help is appreciated.

Thank You
