I have a 99 Plymouth Grand Voyager SE the other day I was driving and I heard a pop, and the engine shut off. It costed about a hundred yards and then I pulled over when I looked underneath it there was transmission fluid dripping from the back firewall side there was a big puddle on the highway back where it went pop.can't see anything from the top, front, or bottom the weather's been real cold here so I haven't got it in jacked up yet just wondering if there was anything back there that could pop out?
