I have a 93 Aerostar xlt with the 4.0 v6 and auto trans that when put into gear has to be revved for it to get in gear and the it slips in and out sometimes while driving it's not a low fluid issue was the first thing I checked also the SRS light is blinking not sure if that a trouble code or if it has a check engine light somewhere sometimes it stays in gear once it warms up and you're on the highway not using much brake but stop an go traffic and city driving is touchy lol and ideas?
