Truck been running fine, then went to go to work next day and wouldn't go in any gear(automatic). Lever not engaging any gear. Engine runs and revs, but that is all. Got code PO 876 Fluid pressure sensor switch D circuit. Replaced sensor, and didn't fix problem. Now getting codes PO988, PO731, PO876, PO882, PO871, PO841 & PO846. Any ideas?

 

Welcome to DF! Moving this to Fourth Gen Ram section for ya.

 

I would start with the P0882 code. That is a circuit problem. I would check the fuse for the transmission relay. Do you still have a powertrain warranty? By any chance did you have a any service work on the transmission?
