TECHNICAL SERVICE BULLETIN 20-2083
10R80 Transmission – High-Pitched Whine Noise - Built On 21-Oct-2019 And Through 16-Dec-2019 20-2083
16 March 2020

Model:

Ford
2020 F-150
Transmission/Transaxle: (10R80)
2020 Mustang
Transmission/Transaxle: (10R80)
2020 Ranger
Transmission/Transaxle: (10R80)



Issue: 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.

Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all of the following criteria:



• 2020 F-150/Mustang/Ranger

• Vehicles built on 21-Oct-2019 and through 16-Dec-2019

• 10R80 automatic transmission

• Customer concern of high-pitched whine noise coming from transmission

Repair/Claim Coding

Causal Part: 7A415
Condition Code: D4

Service Procedure

1. Isolate the high-pitched whine noise condition by road testing the vehicle at normal operating temperature, use the Automatic Transmission Select Shift feature to select and hold 3rd gear while driving on flat ground. The high-pitched whine noise peaks at speeds between 30-40 km/h (18-25 mph) during light acceleration and while coasting down in 3rd gear. The high-pitched whine noise goes away when in NEUTRAL.

2. Is the high-pitched whine noise present?

(1). Yes - proceed to Step 3.

(2). No - this article does not apply. Refer to the Workshop Manual (WSM), Section 100-04 for normal diagnosis.

3. Remove the transmission. Refer to WSM, Section 307-01.

4. Disassemble transmission, perform only the necessary steps to remove the output shaft and planetary carrier No. 4 assembly from the transmission case. Refer to WSM, Section 307-01 > Overhaul.

(1). It is only necessary to remove the following:

• torque converter

• transmission fluid auxiliary pump

• main control assembly

• all four speed sensors (intermediate speed A sensor, intermediate speed B sensor, turbine shaft speed sensor and output shaft speed sensor)

• fluid pump

• output shaft seal

• front support

• clutch and planetary assembly

• output shaft and planetary carrier No. 4 assembly

5. Remove the inner output shaft bearing, fluid passage sleeve and outer output shaft bearing from the transmission case. It is not necessary to remove any other parts except for the bearings and passage sleeve. Refer to WSM Section 307-01 > Disassembly.

6. Install new inner output shaft bearing, fluid passage sleeve and outer output shaft bearing into the transmission case. Refer to WSM Section 307-01 > Assembly.

7. To reassemble, reverse the removal procedure. Refer to WSM, Section 307-01 > Overhaul.

8. Install the transmission. Refer to WSM, Section 307-01.

Thank you FordTechOne. Looks like a big job for service tech .

 

[BC119]

Thanks for the update @FordTechOne ! In your opinion, do you think it is worth having the entire trans taken apart to get rid of a whine?

 

[Woolaroc]

@TRMFAM

 

[Begone]

Yes!!! Thank you!! Finally!! I’ll be taking mine in ASAP! This whine is getting worse and it’s driving me crazy!!!

 

[FordTechOne]

Thank you FordTechOne. Looks like a big job for service tech .

You're welcome. It is certainly no small task, but nothing out of scope for a transmission technician. They literally pull transmissions out, tear them down, rebuilt them, and re-install them on a weekly basis. This procedure requires no rebuild; no sub-assembly tear down is required, as they remove the internals as an entire assembly. From there they remove Planetary #4 and the output shaft assembly and then replace the output shaft bearing and fluid passage sleeve. Installation is the reverse of removal.

Thanks for the update @FordTechOne ! In your opinion, do you think it is worth having the entire trans taken apart to get rid of a whine?

Luckily, the entire trans does not need to come apart. The technician only needs to remove the clutch/planetary assembly as a complete unit to access the output shaft bearing. Based on the TSB, the bearing whine appears to be the result of a lack of lubrication to the output shaft bearing caused by the fluid passage sleeve. When bearings have insufficient lubrication, they may not necessarily fail but they will certainly make noise. Personally, I would have it repaired.

 

[silver_bullet]

I’ve got a truck built on 3/19, with the whistle/whine, would this repair apply to mine or is it a different fix?

 

[preston707]

I sometimes hear it every now and then, that is weird.
