Official summary
Some 2020-2021 Transit vehicles may exhibit a harsh engagement into drive. The vehicle may or may not have an illuminated malfunction indicator lamp (MIL) and diagnostic trouble codes (DTC) P0772 and/or P2704 in the powertrain control module (PCM). This may be due to sticking valves in the main control valve body. To correct the condition, follow the Service Procedure steps to perform the transmission accelerated main control break-in routine and/or overhaul the main control valve body.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
