Alright so just got a jeep from a friend says engine lights on so I connect my code reader an get codes for

P0841 trans fluid pressure sensor/ switch a circuit

P0846 B circuit

P0988 E circuit

P0876 D circuit

P0871 C circuit

P0882 Tcm power input signal low

 

 

My question is what steps should I take to figuring the problem?

What parts am I gunna have to replace?

And is this simply a transmission wireing harness issue an how do I obtain a new harness?

Noise will be bushings on front diff. If it's not slipping, it's not torque converter so would go for changing the sensors flagging up or at least taking them out & cleaning them up in case they have crud in them
