What transmission cap? The question makes no sense.
You fill it though the resivoir cap
The radiator cap is on the coolant reservoir, which is mounted on the passenger side fender for S series Saturns.
I just learned yesterday you have to take it to a GM or Saturn dealer as it is a sealed transmission, they have a special tool. If you attempt to remove the cap yourself it is spring and pressure loaded so it will pour fluid everywhere and you won't be able to refill it or put the cap back on. This is what two mechanics told me and from looking at the cap I feel pretty sure they are correct.
It doesn't exist. On the top of the transmission by the firewall of the car, if you look down on the transmission with a flashlight, you will see a red plastic cap. That is where the dipstick goes, and you can buy it from your Saturn dealership. When you go in to buy it make sure ypu tell them how cheap they are not including a transmission dipstick with the car.
There is a cap under the hood on the valve cover that says ADD OIL HERE
The transmission fluid fill cap on a 1989 Chevy school bus with a diesel engine is under the air filter. The air filter has to be removed to see it.
Check the top of the trans axle, facing the car on your right , red cap that reads transmission fluid.

Gas Cap is not on tight, or the seal leaks and you need to replace the cap.
where would I find fill cap for transmission on a caravan?
If it is a manual transmission, there is no dipstick. You remove the filler cap on the top of the transmission , then remove the hexagonal plug near the cv shaft on the drivers side. Fill the transmission with Dextron 3 until it comes out of the hexagonal plug hole. hope this helps, Glen
If Im not mistaken, the Pressure cap for a Saturn is the twist on cap on top of the coolant resovoir, if the cap say under pressure then that is it and to add coolant to radiator you fill it thru the res.
