Code p2160

[Bobbie]

I was trying to back a trailer up hill in 4x4 when it acted like it didn't. Want to move.  Know I have a pending code of p2160 and in auto 4. Wheel drive it doesn't want to back up.  How would I fix this?

what year is the truck 2160 is a speed sensor code and if you are in auto 4x4 it cant detect wheel slippage and wont engage try just putting it in 4x4 instead of auto

Its a 2014 silverado.  And I was in just 4x4 when it happen.  Now code is gone but have hard time shifting gears it goes too 5000rpms sometimes  before shifting and going in reverse
