I can't seem to found where my transmission fluid gos is it by the coolant container>? Its not labeled so I don't know it's a 1993 Ford escort

I use a funnel and poor mine in the dip stick hole. I can never find a cap for transmission fluid on any vehicles I buy and that is what my mechanics do. You have to be careful to not over fill it and check it with the motor running. You can also go to a gas station that does auto repairs and they will charge you a couple dollars but then you don't have to worry about over filling it.
