inside of transmission vent rubber tube, there is a vent ( looks like a plastic washer with small hole} might be easier to fill trans with vent washer removed, then afterwards put vent washer back into tube. Otherwise, it takes forever to fill transmission with new fluid...just a lil tip
So if it gets wet from rain, etc. is that why you will get codes; pre collision not available, service engine immediately, check engine light ??? because where I live its rains a lot in the fall season and my Maverick did this just the other day, barely made it home.....
