Hello,
I have a 2002 Chrysler 300M. It has started shifting hard in low gears, and when in high gears, it will not down shift. Have to pull over to side of the road, and turn car off. Then, turn car back on. It seems operate as normal after that for a little while... It seems to do it more after the car has warmed up. Tried flushing the transmission. Tried putting Lucas oil in it. Someone suggested the transmission shift module might be the problem, but there is two of them they say. Any help regarding this problem would be great.

Thanks,
ronmurphy
