2002 PT Cruiser
drops into neutral usually around 39mph. car was in an accident and the automatic transmission radiator
was replaced. Fluid level is good. Car just started dropping into neutral on its own. At some point it seemed to get stuck in a lower gear which felt nice because it stopped falling into neutral, but the Check Engine
Light came on. After stopping and restarting the shift was back to dropping into neutral again. OBD codes were P0562, P0700, and P0888.
I removed the battery
and cleaned the posts because they looked corroded. This also reset the ECM. Dropping into neutral problem remained and, after a day of driving, it did the same thing where it gets stuck in low gear and Check Check engine light came on. Same codes.
I have a power steering leak, a busted upper engine mount, some wheel bearing loose, and a broken cover on my fusebox. I took it to the dealer. They cleared the codes, and drove around the lot. They said it was shifting fine after resetting the codes. However, once I drove off and got at almost 40 mph, the problem started again. I went immediately back the dealer who said it's probably a wiring problem or corrosion in the fuse box. I cleaned out the fuse box very well and replaced all fuses and the problem still exists.
