Automated Eaton 10 speed shifting weird

Well today as with many days the transmission acted up again to the point where it stayed stuck in 6th gear abs wouldn't come out. I coasted into rush truck center and asked if they could check it while it had duplicated the problem. I refuse to set tractor brakes (I set trailer brakes instead) in case it cleared it. The tech shut it off after reading codes and it wouldn't start because it was still in gear. The tech then proceeded to trick the drive shaft and wait a few minutes. It started.

Upon looking at service range, we noticed it had a calibration for shift points associated with a x15. My truck has an isx.

We changed that, and that seems to make shift point crisper (possibly placebo effect).

Right now the prognosis is the wire harness due to much corrosion. X-y shifter shifter is not recommended at this moment.

Its out of warranty by 3 months according to dealer. I'll call eaton tomorrow and see if anything can be done.

Code 51,73,13,74

I learned the hard way with corrosion and my Ultra Shift. The plug on the computer was corroded and burnt the computer up. Replaced the harness and computer, high dollar. Best thing with the Ultra shift is keeping the grounds and battery terminals clean. Unplug all the plugs and put that electrical grease on them. Just be careful not to bend the prongs when putting them together. If you have you really need to learn it so you don't get ripped off.
