Probably lost the 4-5-6 clutches... or the hub came apart!

 

Could be? I have to check if I have any codes. I would think should be one set. Piston cracked maybe or may be a bad solenoid

 

4-5-6 being lost is usually something in that clutch pack hub.... usually the clutches are burnt and steels are coned in them... typically mechanical failure doesnt set codes unless its bad enough it either maxes taps out or is slipping really bad!
