Summary

Some 2020-2021 Transit vehicles equipped with a gas engine may exhibit a harsh engagement into drive with or without an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0772 and/or P2704 in the powertrain control module (PCM). This may be due to sticking valves in the main control valve body. Most vehicles will improve and no longer exhibit the condition after the first 8,000 km (5,000 mi) of driving. 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.

Owners of these vehicles have filed 25 complaints in the transmission category.
