So I reinstalled the speedo gear as directed in the tail housing and it's not working. I've got the yellow gear.. Which according to the chart is a 33 tooth gear. So I indexed the housing on the "32.38" notch... What am I doing wrong???

 

You plug in everything after tcase install?

 

Yup... Only thing I can figure is I didn't push the housing in far enough... Jeep is also throwing a P500 code. So could be electrical?

 

Check your wires leading into the speedo plug.
