Complaint A harsh 5-4 downshift can be felt during deceleration while braking or coasting. It may be mistaken for a hard brake engagement Cause In certain driving scenarios, the transmission torque adaptation for the 5-4 downshift is recorded at a higher value. This skews the learning which leads to harsh engagement of the B06 clutches, creating the harsh 5-4 downshift Remedy "Phase 1" software was released 11/14/2024 to slow the adaptation process and reduce the frequency of the complaint. However, it was possible that the clients driving style could cause suboptimal adaptations, and this would result in the concern returning sooner than anticipated for some vehicles.
