Guys, there might be different reason for similar issues. Truck not going into gear or dropping down into neutral gear could be just computer problem not recognizing which gear it needs, or it could be clutch slip/clutch disengagement. What you can do IS check your code. Push the key and turn into ignition few times quickly and your screen should show a code. if it is 26 or 27 then it is clutch issue.

What people don’t understand is. Automatic transmission you need to let the truck warm up. Water temperature is down to 0 and you want the transmission to do its thing. Not happening. Warm the truck up and try again my friend

Same problem but Only in the cold morning . Have to wait till shiftgear get warm at least 81°F than goes better

hi how are you man my brother having the same problem how did you fix it

[zafarjon]

You should warm it up a little more. I have exact same problem. After 10 hours of truck being off, I usually warm it at least 20 monutes. Once the water is between 0-100 F the truck shifts better.

I have one now with USX. This damn thing can't decide what gear it wants when coming to a stop and I have to manually shift it going up a hill heavy. I'd rather have a manual transmission and I will never sit two days at a dealer like one of you said. I'd leave the damn truck there for someone to go get! Mercedes Benz will never have me as a customer either because they own freightliner. If that's how their service is too, I'd never own a benz.

Its an issue and needs to go to shop. But if u needs to move it out drive to shop, u need to put transmission in neutral and turn engine of for 10 to 15 mins then crank back up and then try to put in drive. If it doesn't go in drive then put in reverse and it should go in. But whenever it does just do not turn engine off until u reach ur destination. It will stay in drive until turned off

i have an emergency question if you can help please … I have 2016 Cascadia with dt12 automatic transmission and my shift controller on the transmission is damaged … does that make my truck not to start at all
the guy who checked my truck with the computer said so but I kind of have a doubt as it doesn't make sense unless if you confirm
i also changed the cpc4 and reprogrammed it to my vin and still doesn't start the truck and that's the only error it's showing

just to mention ... the cpc was changed as it was stolen from my truck and i bought 2 used ones ... one is not programmed and it does crank my truck but won't throttle or put gear on .. and the second one is the programmed to my vin and doesn't crank the truck at all

mines currently at the dealer with the same problem as well as numerous other stop engine problems, Mine would refuse to go into gear and just fart sound like it was trying to find a gear. Once it warmed up it started working problem free with no issues unless it started running hot in the summer pulling 45k loads over the mountains and temps hit 250f+ Then it would just dog out and fart the same way.

What could be the problem the same thing happened during morning time in my 2017 Frightliner cascade automatic transmission.
What could be the problem?

This is a split pin issue, once the trans is warmed up the pin moves freely. There is a fix for this now, all trucks that experience this issue can be fixed at no charge at your local FTL dealer as long as the truck is within warranty still (5 years 750K miles).

I have a same problem and sitting at freightliner for 2 days. How did you get it fix. What was the problem?

[Familyfun]

Could this be the same issue as always I warm the truck up sometime the dt12 goes in to Dr or rev very slow when I switch the shifter I did replace new shifter check engine light does not come back anymore so far

[mahera]

what was the problem and how you fixed ?

[wba]

Hey we have the same transmission and everytime we press on the brakes or put it in drive or reverse it lets out air from the transmission is that normal?

[sunjulee]

I replaced busing split pin.
Now it is ok.

[USATruckersUSA]

Need to replace transmission bushing split pin

[ziondizzy]

This guy is the definition of seat meat

[MichaelBelenski]

Let the water temperature rise to 120⁰ degrees Fahrenheit you'll be fine.

Does anyone know anything about swapping out a dt12 for a eaton amt13
