Unfortunately new drivers suck at driving stick and i’m getting lazy. But this will come in handy for my future auto peterbilt purchases. Thank you for the post!

I got the problem, how I can get it fixed please?

[@sukhjindersingh9331]

What happen bro did you get fix it got same problem got transmission fault def light these light gauges got so crazy got stop engine light got active then after few minutes inactive it’s crazy t680 2020 Cummins but there no transmission codes

Code 27- probably one of coil springs is broken in clutch Code 64- shifter stucked at neutral. Code 71- is transmission fault by itself. When mechanics remove if clutch is really bad they will check shifter also , if you have to replace both it costs around 7500-8500$ . That’s painful process, takes time . Then mostly fault code 71 will gone . If not there is hidden problem on transmission . Good luck everyone

Code 71?

[@kirpalsingh5077]

I have just started the code is 27 . can u advice what to do ?

[@DDTruckDriver]

In the video it shows you code 27 is clutch disengagement. My guess is it would be one of the fingers on the clutch is broken which is not easily fixed

you're gonna see issues regarding speed sensors (input, intermediate and tail shaft). issues related to rack position (which is also detected by sensors). issues with the rack itself, worn out and loose mechanical moving parts underneath the x-y actuator assembly. wiring harness rot and deterioration, the actual actuators themselves. best scenario is retrieving codes, determining which are- what we call- hard{current faults) then being able to read what the TCM is reading. has nothing to do with the driver, anybody can mash the gas pedal, has everything to with the shop personnel knowing what they're looking at..

[@DDTruckDriver]

How do you like to pull the codes so you know that information?

[@jazzlee8476]

I didn’t even get a number I got letters 😩. “PD”

[@DDTruckDriver]

When you get PD that means Product Diagnostic mode. That means you did the wrong number of key turns. I think I covered that in the video?

Company that I work for bought 6 t880 with those eaton automatic transmissions. The thing is a piece of junk, so rough to ride, no driver last more than 3 months driving it.

[@DDTruckDriver]

They certainly aren't as good as the newer auto transmissions.

[@ptmxpress372]

Hey boss I have the same problem so what do you eventually did ? Please let me know if you can help thank you

[@DDTruckDriver]

In my case it ended up being a defective clutch fork design that required a complete new clutch. Eaton figured out the problem years ago but there were about 6 weeks of trucks that were affected by this. If your truck was built in Nov-Dec of '17 then it may have the same issue.

[@1905ny]

I have same issue have fix the issue

[@DDTruckDriver]

@@1905ny Are you saying you did fix it or need to know how to fix it? In our case it required towing to the shop because the fingers on the clutch broke and stopped things from being able to engage.

[@1905ny]

@Double D Distribution sorry for confusing.. I got same problem. did change clutch but same issue goıng on.. basically service don't now either much ..I'm trying to figure out my self before I take service again. there are many scenarios. let me know what else u did to fix please

[@DDTruckDriver]

@@1905ny It was a new clutch. That is what we had to do to fix it.

[@HgfddgJhgyjh]

I just give me F nd won’t shift gears just put new clutch
