The following Transmission Control Module (TCM) calibration improvements are available for vehicles equipped with WA580 Automatic Transmission (Sales Code DGJ) and are broken down per engine application.3.6L Engine Hanging in gear during HOT ambient temperature conditions and high engine loads. Excessive pedal needed to downshift in high altitudes (i.e. passing). Poor shift quality, or high transmission temperatures during track or sport driving.5.7L Engine Hanging in gear at high engine speeds during aggressive driving. Gear shift point enhancements during high load or race track driving. Excessive pedal needed to downshift in high altitudes (i.e. passing). Poor shift quality or high transmission temperatures during track or sport driving. Improved acceleration response from speeds greater than 36 Mph (58 Kph) (Japan Market Only). Bump sensation felt during deceleration or braking.6.4L Engine Bump sensation felt during deceleration or braking. Inconsistent downshift during Wide Open Throttle (WOT) accelerations at highway speeds (i.e. passing). Transmission enhancements to improve acceleration while in reverse going uphill on steep grades.3.0L Engine (LX Only) Erratic excessive shifting during low speed, light pedal driving.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10221022-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10221022-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10221022","components":[{"id":"air-bags","name":"Air bags","parent":null},{"id":"electrical","name":"Electrical system","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CHRYSLER","model":"300","year_from":2013,"year_to":2013,"match":"exact","vehicle_ids":["2013_chrysler_300"]},{"make":"DODGE","model":"CHARGER","year_from":2013,"year_to":2013,"match":"exact","vehicle_ids":["2013_dodge_charger"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
