2013 Shifting issues

[threehitquit]

I have a 13 and has been having issues. It seems randomly, my transmission will shift or downshift and get "stuck" in 3rd or 5th gear. The speedometer goes to 0, my mileage goes to dashed, CEL and the wrench comes up. Eventually it may shift out of third, sometimes turning it off and back on will bring it out of it. Code pops up as Output shaft speed sensor, which is embedded into the lead frame as far as of can tell. Truck has had the recall on the 6r80 completed, and I am after the mileage on the warranty after the recall. Any ideas other than lead frame?

Thank you,

Is your battery / alternator / fuses ok? I always try to check if that's the culprit before moving on to something else.

For fuses, check the following:

On the engine fuse box:

• Fuse #74 (Transmission Control Module) – 15A
• Fuse #76 (Powertrain Control Module - PCM) – 20A
• Fuse #13 (Ignition Coils / PCM) – 30A
• Relay #5 (Transmission Range Sensor / Starter Relay)

Passenger fuse box:

• Fuse #33 or #34 (PCM or Transmission Controls)
• Fuse #22 (PCM Keep Alive Memory)

If all looks good then, I'd check:
- Transmission wiring harness
- Transmission fluid
- Trans-related ground connections

I will look into those, thank you!
