Common Problems A 2006 Chrysler 300 May Have (And The Cost To Fix Them)
Nearly 400 2006 Chrysler 300 owners, on RepairPal and several others on Carcomplaints, both reported a stuttering or uncharacteristically harsh shift from one gear to another. The normally smooth ride of the 300 was transformed into an awkward and jerky drive that left many owners frustrated. Some explained, “[The] car won’t shift automatically when rpm is high. Engine light on.” Others described, “the car shakes/shutters around 40 mph.”
There are a few methods of correcting these issues, such as updating the powertrain control module (PCM) and transmission control module (TCM) software, or outright replacing the modules. The transmission control module controls gear shifting, while the powertrain control module is essentially the mind of the car. One owner explained that their dealership replaced the PCM module for $490. However, the average cost for a replacement PCM is as much as $2,000 and a replacement TCM is around $813 plus labor. If you experience this issue, hopefully a software update will correct the problem, as it’s a cheaper alternative than outright replacement.
