Ok hive mind, I need your help!

no flashing m&s lights
no amigos
“sport” mode “works”
shifter and dash show actual gear selection

in high range I only get first and reverse

However!

Low range manual mode I can shift through gears.

any ideas on what I should be looking for? I don’t have a nanocom, is this something that a reset or code clear on that would resolve? Appreciate any help!

 

Been going over the connections on the ACE box, seems like I might have flip flopped a few of the throttle position wires going into the ACE box.

 

I think you are on the right track looking at the connections to the ACE box. If those were mixed up, I could imagine strange transmission behavior.

 

Replying here for closure. TPS was wired in wrong. So apparently if you have TPS issues the rover will not shift out of first gear.
