# Service bulletin TSB 20\-2083

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10172966
- Published by NHTSA: 2020\-04\-02
- Manufacturer's number: TSB 20\-2083
- Manufacturer's date: 2020\-03\-17
- NHTSA component: POWER TRAIN

## NHTSA's summary

Some 2020 F\-150/Mustang/Ranger vehicles equipped with a 10R80 transmission and built on 21\-Oct\-2019 and through 16\-Dec\-2019 may exhibit a high\-pitched whine noise coming from the transmission at low speeds during light acceleration or coasting. This may be due to the outer output shaft bearing. To correct the condition, follow the Service Procedure steps to replace the transmission inner output shaft bearing, fluid passage sleeve and outer output shaft bearing.

Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble code \(DTC\) P0420 stored in the powertrain control module \(PCM\). This may be due to the software in the PCM.
- [TSB 26\-2112](/bulletins/11030178.md), 2026-03-23, Service bulletin: FUEL/PROPULSION SYSTEM; UNKNOWN OR OTHER; POWER TRAIN. This bulletin supersedes TSB 26\-2059. Reason For Update: To add missing labor operations. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: \- No upshift past second gear \- Unable to achieve third gear ratio \- Illuminated malfunction indicator lamp \(MIL\) with DTCs P0757 and P2701 This may be due to a damaged one\-way clutch \(OWC\).
- [SSM 54592](/bulletins/11029081.md), 2026-02-27, Service bulletin: POWER TRAIN. For 20172026 vehicles equipped with a 10R transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, located in Section 307\-01 \> Diagnosis and Testing. This updated procedure improves the diagnosis of customer reported transmission concerns and aids in locating the proper root cause. During diagnosis and testing, details regarding whether the condition is more prevalent when the vehicle is hot or cold, throttle percentage at the time of occurrence, vehicle speed, the specific shift involved, and whether the issue occurs during transmission engagements \(N\>R, N\>D, R\>D, or D\>R\) should be noted. Engineering requests including these detailed operating conditions that will significantly assist with root cause analysis. Diagnosis, testing, and repair should use established labor times outside this article.
