Yesterday after getting off the freeway. I let up to coast to a light. As i was coasting i heard a pop. Little longer i gave the truck gas to pick up some speed Truck reved like it was in neutral. Pulled to side of road put it in park truck rolled back like still in neutral. Put truck in 4x4 that held the truck. Didn't see anything leaking. other than the small trans leak I knew about before. Got in truck started moving 4x4. kicked out of 4x4 truck drives.

Now it sounds like my truck is in 4x4L but its not. Truck will only go 40 at 3k. getting to 40 truck will go over 3k. Once im at 40 and 3k truck bickers like the fuel cut off kicked on. Little scan gauge I have beeps saying "MPH 104 Reached max speed set 93" ( that's to let me know if I go over 93)

 

Likely a transfer case issue...if it's not the transfer case manual shifting mechanism (or electronic engangement ciruit, if you have one), the transfer case will have to be pulled for servicing.

 

Sounds like the transmission output shaft path back to the rear is broken if Park will not hold the truck.
Easy to check by jacking the rear with both wheels off the ground and rotating the drive shaft first in neutral then put trans in Park.
If you can still rotate the driveshaft in park, the output of the trans is broken internally at some point
In 4x4 the front is doing the holding in Park.
It does sound like you shifted the 4x4 into 4L.
See if it will come back to 4H.
If there is no noises the front wheels will pull the truck so you can move it around.
Good luck.

 

Ever since i took it out of 4x4. Never drove in 4x4 more than 10 feet. Front wheels are not enguaged. the rear is doing to work. Driving and in park holding the truck. Seems to be in 2L

 

Guess things have changed.
Do you still have an issue?

 

Nothing has changed. Something with the transfer case wont let the truck go out of low gear. I can shift it to 4x4 and 2wd but stuck in lo no matter what. Truck dose go into 4th gear. will not go over 42mph. its a mph thing not rpm like I first thought. If i try to put the transfer case into N it dose not change. Its in 4x4 or 2wd I forget what it did. But still in Lo range. So somehow my truck got stuck in Lo range.

 

my truck shifted into neutral without touching a gear shift i was going down a hill when this happened so i stoped put it in park so i could check things out and it started rolling down the hill. i got back in and put truck in 4hi to see if trans case would engage, and it did then tried to put it back in 2-wd hubs came unlocked but i was still in low range.

So deff a transfer case issue right? I was told these have chains in them? That could have been the clunk i heard..

Now can i rip the T-case out and still drive my truck?

 

No. The power runs through the transmission to the T case then to drive shaft. If you are in a low gear, the T case is engaged. That is the only way, the low range is derived from the transfer case, not the transmission. What makes you think that the rear wheel are doing the work, because the 4x4 light is off? That does not mean that the T case is not stuck engaged. Obviously there has been some sort of catastrophic damage if the tranny will not hold the truck in park, no reason to think that just because the lever is in 2wd, that does not necessarily mean the T case is not in another. If your in low range, your in 4wd.

 

Dirt roads. I know its In 2wd untill I put it in 4x4 than 4x4 is enguaged. Take it back out and back in 4x4. Rear wheels only spin. When put in 2wd.

 

Park works just fine now. But its still stuck in low range

 

I have a difficult tme following what is going on the way it's being discribed.
Low range is usually 4L only.
If your saying Low range in regular drive, thats something different.
Low range also changes the PCM shift sked along with the change in power flow through the transfer case.
Let's start all over again and tell what the conditoion is 'now'.
Leave out what happened in the past.
A. Does the truck work in 2H only?
B. Does it work 8in 4H only?
C. Does the front hubs engage in either 4H and or 4L?
D. Does the shift sked ever go back to normal in 2H or 4H?
Depending on these answers I can likely point to the problem area.
There are a number of areas that have to work at the same time in order to effect proper operation.
What do you have now?

 

A. Does the truck work in 2H only? No. Won't goto 2hi
B. Does it work 8in 4H only? yes. But it is sill in LO
C. Does the front hubs engage in either 4H and or 4L? yes
D. Does the shift sked ever go back to normal in 2H or 4H? Sked?

The truck is stuck in Lo gear no matter if front wheels turn or not. I put truck in 4HI i have 4wd but in Lo gear so 4lo. I put in 2Hi I have 2Lo I know its in 2wd because i can spin the rear wheel where in 4wd i cant spin any.

 

Is it the transfercase or Transfercase Controls....?

 

I'm saying the t-case it self. I can sift it to 4wd but when i try N or 4lo nothing changes it stays in a Lo gear. If i have the t-case lever in 2wd it is 2wd but in Lo so it unlocks my hubs but dose not shift to the Hi gear. so the only thing my t-case shifter dose right now is put it in 4x4 or 2wd. (4lo or 2lo)

 

I'm still wondering if there are maybe 2 cables to actuate transfer case positions, maybe 1 cable came off/broke??
