T680 auto transmission issue

Common.
Where do you have your eld plugged in?
That's where the dealer will start. Could be ground. Impossible to tell without a computer

 

Why are you pushing the buttons?, let the computer decide when to upshift/downshift. The computer is telling you ‘don’t touch those buttons’. lol

 

You more than likely have a Eaton Endurant. t is Eaton answer to Volvo Ishift, DT12 etc. Many recalls for this unit from Paccar. Check with your local dealer.

 

What ever happed with this situation?? I am experiencing the same thing

 

Hi, what ever became of this situation? I am experiencing the same situation, I also went to start truck and it seamed dead, but had plenty battery, the trans didn’t recognize neutral, played with shift stalk and it started, wondering if it’s a defect in shifting stalk??

 

The truck I drive does the same thing does not like for the shifter or Jake’s to be used happens most when loaded and in hills or traffic. Basically any time the transmission has to work hard at shifting. Had in shop a few times new clutch, new shifter arm, several computer updates and recalibration done same crap. I have loged over a hundred thousand miles driving this truck with the issue. O and when you bring it to the shop unless the dash is lit up they can not seem to see the event with their computer.

 

My truck started having same problem when in manual mode gear shifting. I have kenworth 2022 t680 cummins 420K miles. Did you find any solutions? Please share with us.
