My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

Sounds like you have a XY shifter fault. There is an electrical issue with it or the shifter itself is starting to go out. I would have the shifter tested with the Eaton RoadRanger software and see what it is doing. You can also pull up the errors the transmission shows with the missed shifts. With all the inactive codes, I would suspect a electrical issue in the harness that powers the transmission. They are all shifter related as well so that is why I am at a toss between it being power related or the shifter motor itself.

If the power tests good, then I would replace the XY shifter.

I see you viewed this and this is still showing as an open question due to no positive (3 stars or more) rating.

Were you not pleased with my service to you or is there a rating issue? Please let me know if you still need assistance with this, if there is a rating issue, and/or you need more time to respond.

I like to make sure all my customers are satisfied since you did pay a deposit for me to assist you, whether I’m paid by a positive rating feedback or not.

We can continue where we left off or start over if needed. Also, if you need diagrams, instructions, etc please don’t hesitate to ask.
