Hello. I recently bought a 98 explorer with 5.0 to make into a trail rig. It has 117k miles and its suppose to have a bad transmission. So it's been setting a few years without a battery in it. Found a transmission leak on the cooler line and it's about out of tranny fluid.so I fixed it and dropped a battery in it. Turns over it no fire and the security light is flashing rapidly. Does anyone know a way to reset the security system. Thank you. When I get it running plan on swapping transfer case with a manual shift one and putting on small lift. Can't wait to play.
