I have a 2019 5.0 and the trans has been slipping for the past few weeks only when its cold. I checked the fluid and it looks a little below the 6 mark to me. Does this look low enough to cause cold shifting issues? Thanks

 

Was this reading taken at operating temperature (~200degF)?

 

yes

 

Level needs to be between 5 and 6, you might be a quartish underfilled.

 

Got a code P07f6-00 today. Any help with this code? Thank you

 

code P07F6-00 indicates a 9th gear error in the 10R80 transmission. This code is often associated with harsh engagements, poor shift quality, and potential loss of 9th gear. It is commonly found in 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang, and 2019-2023 Ranger vehicles equipped with the 10R80 transmission.

Possible Causes:

• Software Issues:
  The transmission's adaptive calibration may not be compatible with the hardware break-in, leading to incorrect shifting.
• Valve Body Issues:
  Sticking valves in the main control valve body can cause shifting problems.
• Solenoid Issues:
  The transmission solenoid ID strategy or electrical issues with the solenoids can also trigger the code.
• Clutch Cylinder Issues:
  Axial movement of the CDF clutch cylinder sleeve can lead to gear ratio errors.
• Internal Transmission Failure:
  Internal problems within the transmission itself can also cause the error.

Troubleshooting Steps:

1. 1. Check for other DTCs:
   If other transmission-related codes are present, diagnose and address them first.
2. 2. Reprogram the TCM and PCM:
   Using the latest software, reprogramming the Transmission Control Module (TCM) and Powertrain Control Module (PCM) may resolve the issue.
3. 3. Inspect and potentially overhaul the valve body:
   Replace or repair any faulty components in the valve body.
4. 4. Perform an adaptive learning drive cycle:
   This allows the transmission's computer to relearn the unique parameters of the transmission.
5. 5. Consider a transmission rebuild or replacement:
   If the above steps don't resolve the issue, a more extensive repair or replacement may be necessary.

 

Look in the owners manual. It will show proper hot level on the stick. It looks low to me, which could cause a slip issue. my 2012 has a different stick. Get it corrected stat, it might cure the slip. Only one way to find out.

The trans slipping cold is not helping longevity
