Bulletin Summary
Some 2020 F-Super Duty vehicles equipped with a 10R140 automatic transmission may exhibit a harsh engagement/harsh shift/delayed shift with or without an illuminated malfunction indicator lamp (MIL) or diagnostic trouble codes (DTCs) P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F7, P0751, P0756, P0761, P0766, P0771, P2707, P2700, P2701, P2702, P2703, P2704 and/or P2705 stored in the powertrain control module (PCM) or transmission control module (TCM). 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 for the appropriate clutches and/or overhaul main control valve body.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
