Where is the drain plug for the transmission in a 1989 Chevy Celebrity 2.8L?
My 1990 Chevy celebrity does not have a drain plug on the
transmission pan. Your car probably does not have one either. You
could break loose a transmission line from the radiator and add
fluid in the dipstick tube while the car is running until the color
of the transmission fluid clears up. I am guessing you are trying
to change the transmission fluid. This is how I changed my
transmission fluid there are lots of videos on how to do this on
youtube.
