Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: \* An illuminated powertrain malfunction \(wrench\) indicator with DTC P07F7 \* Loss of 10th gear. The vehicle may also exhibit harsh engagements and poor shift quality. This may be due to the sleeve in the CDF clutch cylinder shifting axially causing hydraulic circuit leaks.
- [10236684](https://open.wenmarpro.com/bulletins/10236684), 2023-05-29: Some 2020 F\-Super Duty vehicles equipped with a 6.2L or 7.3L engine and a 10R140 transmission may exhibit an illuminated powertrain malfunction \(wrench\) indicator with diagnostic trouble code \(DTC\) P07F7 stored in the powertrain control module \(PCM\) and a loss of 10th gear. The vehicle may also exhibit harsh engagements and poor shift quality. This may be due to the sleeve in the CDF clutch cylinder shifting axially causing hydraulic circuit leaks. To correct the condition, follow the Service Procedure to replace the CDF clutch cylinder.
- [10203709](https://open.wenmarpro.com/bulletins/10203709), 2021-12-01: Some 2020 F\-Super Duty vehicles equipped with a 10R140 automatic transmission may exhibit a harsh engagement/harsh shift/delayed shift.

- [10201636](https://open.wenmarpro.com/bulletins/10201636), 2021-09-30: Some 2020 F\-Super Duty vehicles equipped with a 6.2L or 7.3L engine and a 10R140 transmission built on or before 1\-Apr\-2020 may exhibit an illuminated powertrain malfunction \(wrench\) indicator with diagnostic trouble code \(DTC\) P07F7 stored in the powertrain control module \(PCM\) and a loss of 10th gear. The vehicle may also exhibit harsh engagements and poor shift quality. This may be due to the sleeve in the CDF clutch cylinder shifting axially causing hydraulic circuit leaks. To correct the condition, follow the Service Procedure to replace the CDF clutch cylinder.
- [10191169](https://open.wenmarpro.com/bulletins/10191169), 2021-05-04: 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.
