I attached a picture of the power supplies to the X/Y shifter, check them to be sure there is power to the module.

the most common issue is the X/Y shifter or harness. the fact it is stuck in 10th concersn me. it may also be an internal issue in the trans.

do you have any air leaks???

No air leaks that I can fine. I checked the 12 pin connector going into the ECU for voltage I read that on a website and pins 1 A,B there are no volts on that with the key on. Where is this 21 pin connector located?

on top of the trans itself

I googled a troubleshooting flowchart and followed the process through it and found where I was not receiving power supply voltage. I jumped 12 V to that leg and it started working. I will get a more permanent fix once I get back home.
Technician: roybelding, Shop Foreman Freightliner trucks replied 10 months ago

the diagram I sent you had that info on pin 21 coming from the battery.
