The 9-speed automatic introduced in the Chrysler 200 and related models — a case study in how much software calibration matters, with early examples carrying a reputation that later revisions only partially repaired.
This transmission's early reputation was shaped as much by software calibration problems as by hardware — harsh, hesitant, or delayed shifts were common complaints in the first several model years, prompting multiple manufacturer software updates. Later revisions meaningfully improved shift quality, but the gearbox's early reputation has stuck, and it remains one of the more consistently criticised components covered on this site.
Not a guarantee, but a pattern seen consistently across owner forums and independent-garage reporting.
Shift-quality software issues on unrevised examples can be present from very low mileage, not purely a wear-related concern.
Mechanical issues, where they occur, more commonly begin surfacing within this range.
Examples with documented software updates and no early symptoms generally continue more predictably from this point.
Test drive extensively, through a range of speeds and throttle inputs, paying close attention to shift smoothness, hesitation, and any harsh engagement.
Ask whether the transmission has received manufacturer software updates, and consider having a dealer check and apply the latest calibration before or immediately after purchase.
Given this gearbox's reputation, a longer-than-usual test drive is worth the time here more than on most other transmissions in this catalogue.
