If its not slipping or anything, dont touch it. I had a ford e250 I did all the basics to including new fluid and filter. Within half a tank of gas the tranny started to slip and it was a real hand full to drive. The fluid was black and smelled like onions.

If you were to change the fluid the new fluid will eat the varnish from the plates and the transmission may start to slip.
