2002 Dodge Neon transmission problem. Check engine light came on yesterday, so I took it in to check it out. Got a P0700. The guy at the shop said it may be nothing, and just keep an eye on it, as there were no issues other than the light coming on. Today, on my way home from work, I stop at a red light, and when the night turned green there was a slight hesitation in the transmission engaging.  I drive a few blocks more, and slow down to make a right turn, and when I try to accelerate, the transmission had completely disengaged, as if I was in neutral.  Pulled over just long enough to call my wife to let her know that I had broken down. Started the car back up, and the transmission was engaging, so I tried to make it the last couple of blocks to home. All the way, the tranny was slipping in and out of gear. What's going on?
