Replaced new transmission case motor due to 4wd needs service. Came up in code for replacement. Now code says low ground reading. 4.7 and should be at 6+. Any ideas?

Welcome to 2CarPros. Could you post the codes you had please? It sounds like a harness issue, but I want to look at the code setting criteria and wiring. Thank you.

Okay, it sounds like a harness issue. I would pull the harness connector and check the pins for corrosion as well as pin fitment. A bad connection would cause issues with current flow.
