My brothers ram won't go into park, 4x4 won't engage, traction control light on, abs light on as well as check engine. The codes are u0101, u0140, p0850, p000. I googled all codes and know wha they are. Anyone know what has caused all these computer related codes?

 

Did you inspect all the wiring to the transmission and or the control module itself.

Are any mini or maxi fuses blown?

 

Where is the control module on the tranny? I'll get him to check the fuses. Looked at the 20 amp tranny fuse and it was ok.
