My Crown Vic was leaking oil by the oil filter. It was fixed during oil change, 2k miles later more leaking Y?

The tranny started lurching at 50-60mph. Possible problems?My Crown Vic was leaking oil by the oil filter. It was fixed during oil change, 2k miles later more leaking Y?
probably a careless oil changer person did not install the new filter properly. they are only concerned with speed. take it to a ford dealer not a cheapy garage. trans could be low fluid or adjustment.My Crown Vic was leaking oil by the oil filter.

you better tighten up the oil filter or get a new one, the tranny is not lurching, the low oil switch is shutting the motor down, to prevent the motor from blowing up because of low oil!
check the oil pressure switch
