How do you check the transmission fluid on a 1994 Ford Aerostar mini-van?

you should have 2 dipsticks. 1 for oil and 1 for tranny fluid. the tranny fluid dipstick is going to be the one in the back of the engine compartment.

if you have to add some. use "dot 3 tranny fluid" and a funnel.

check the fluid level with a warmed up tranny and while the eng in idling to get a proper level reading
