Tranfer case problems

[4xdad]

I was booking down the road at about 110kms and all of of a sudden it seemed like the truck shifted into low gear or 4x4. I immediately pulled over and parked now the truck doesn’t go in to any gear in any range. It is a 2015 Pw I had the tranny replaced at 140k kms after it crapped out. Even at that time it would at least go in to gear. Any ideas

Code1457

The code is an evaporative emissions issue and has zero to do with the issue you describe. Since that truck is a manual shift transfer case I'm not sure how it shifted into 4x4, but the trans might have downshifted to a lower gear.

 

[4xdad]

You are right that code is a nothing burger. But the horrible noise coming from the truck and the fact that I have no gear engagement in any gear. To me that spells wiped out transfer case chain. I have a quote for 4k repair

Without more information there is no way to diagnose, or even guess, the issue. Have you looked under the truck at all? A rear driveshaft u-joint letting go could cause a sudden loss of all power or drive and make some nasty noises. If the driveshat or u-joint letting go would also prevent the Park feature from working as it wouldn't keep the vehicle from rolling. This is very obvious by looking at it. Next step is the transfer case letting go. Keep in mind that the chain only provides power to the front when you engage 4wd and has zero to do with power to the rear axle. If you were in 2wd running down the road it shouldn't have been engaged or had any power to it to fail. If the chain did let go it would likely be a catastrophic event and cause the transfer case to lock up, and of course make some bad noises. Just that if you removed the chain from the transfer case the truck would still operate in 2wd, you just wouldn't have 4wd. The next step is the transmission. Just because it's been rebuilt or replaced doesn't mean it was good. A poor rebuild or bad install could cause issues. Trans could have grenaded or a simply solenoid pack could have failed. Torque converter failed, or even the bolts attaching the torque converter to the engine flywheel could have come loose.

It definitely requires some farther research No gears in any gear and no park either

Have you tried to shift the transfer case into other modes, If it slipped into neutral it would cause most of the symptoms the linkage might not be set correct. put the transmission into N and move the tcase lever into another detent and then try engaging the transmission. Might want to give Transmission Express in Camrose a call and see what wisdom they can shed.

That's actually a good point. If the transfer case somehow shifted into neutral it would have felt weird in the truck and would give you no forward or reverse gears. Try shifting the transfer case into different modes and see what happens.

No go in any gear 4x4 2 hi4 lo 4hi trans maybe. It rolls away when in park. I going drop the diff cover and check that I was going to do a service anyway. What ever it is I need to fix it

 

[JohnCA]

Can you hear the transmission shifting when moving the gear selector? a broken input shaft could do it, don't know if I ever heard it happen to a 6.4

 

[4xdad]

No it doesn’t make any noise or anything it’s like there’s no input at all

If the park position still lets the truck roll I would suspect something downstream of the transmission. I guess it's possible the trans grenaded enough where it also took out the park pawl, but that is not very likely. If it was just the rear diff, it should go when you engage 4wd since the front diff would be pulling it. In any case it is easy to see if the rear diff is the issue without pulling the diff cover. Just jack the rear wheels off the ground and spin the rear driveshaft. If neither rear tire spins with the rear driveshaft there is an issue. But again, if you still don't have any "go" in 4wd than it's not the rear diff or rear driveshaft. This is really pointing to the transfer case.
Have you looked under the truck yet? Make sure the transfer case bolts haven't backed out of the trans! I've seen it happen after trans work where somebody didn't tighten them up. The transfer case backed off from the output of the trans. Again, if you have the rear tires jacked off the ground you can spin the rear driveshaft and see what happens. If the transfer case was exploded I would expect to hear some bad sounds coming from it. Also pop the fill plug off and see where the level is. If low I would pull the drain plug and see what it looks like. Another possibility is that they forgot to fill the transfer case back up when doing the trans work, which could cause a big failure.

Sounds like you beat the truck.

271-D Transfer Case

I never beat on my truck I drive like an old man because I am one. Dropped the rock sliders and skids yesterday. So further diagnostic tests today

 

[JohnCA]

With the engine running if the Tcase is in N and you shift the trans out of park and then try to shift back into P you will get an awful noise of the parking pawl raking across the sprag splines that would tell you the transmission is spinning front to back and the problem lies after the transmission, If there is no nasty noise then you have a problem ahead of the tcase. *Disclaimer I am not saying to do it but that is how I would narrow it to one or the other*

 

[4xdad]

Well holy sh&& the t case has perted ways with the trans don’t know why yet but I will keep you posted

 

[4xdad]

3 studs broken 3 no nuts

 

[4xdad]

Wtf

 

[Wild one]

Wtf

How long ago was it when you had the transmission replaced,as it looks like somebody might have screwed up re-installing the t-case.
