Why does your Chrysler 300M get stuck in 1st gear?
just because u have baught a stupid automatic car, get one with menual shiftingHad similar problem several years ago. There is a sensor in the transmission that, when it fails, will not allow the transmission to shift to a higher gear. When it happened to me, I could not manually shift it to a higher gear. I took to repair shop to be fixed. Not sure if it is a diy project.
