Hey Guys, I have a question.
I'm a little puzzled about why the parking pawl will not engage without grinding which to me says the output shaft is moving when it should not be.
Is it possible the transfer case has a problem and not necessarily the trans, aside from the burnt fluid could it be the fluid was overheated trying to get it to move?

 

Hanky.. While your question makes sense and would answer a few unanswered questions, it is not possible it could be the transfer case.

Let me explain; the transfer case is located on the rear of the transmission and they weigh a ton, it is where the torque is transferred from the transmission to the drive shaft/s allowing movement.

That is about the extent of my knowledge of transfer cases, so that cannot be the cause, because I have no idea how to fix it if it is. It “has” to be something I can fix; my uncle cannot afford to pay to have this done.


Ever notice no matter how much you want it to be something simple it never is.

 

Reading everything I can find on transfer cases and so far they seem pretty straight forward.

What I have found so far indicates the case in this year/model is the BW4405. If this information is incorrect, please help, as I would hate to have to drive all the way back to Virginia to find out from a tag number.

I found a tread entitled “The Borg Warner 4405 Transfer Case Rebuild Diary” and am reading it in case you are correct (Hanky) and I will need to go into it.

Just a note, I hate learning a new trick on someone else’s stuff LOL.

Thanks for your help guys, this is not something I would like to do alone and you are providing great support.

 

If there is a separation of parts in the transfer case, the trans would send power to the input of the transfer case , but the transfer case is not transferring that power/movement to the driveline / output of the transfer case .
I suspect that is what is taking place. Has anyone tried to get the transfer case to go into 4 hi or 4 low ?

 

Had I been the intellectual one rather than you, this test would have likely been carried out. However, me being me, I jumped in with both feet, pulled the transmission and transfer case, removed the transfer case and placed it atop a couple 4x4’s under the car port, placed a blanket and over it and a tarp over that (now 100 miles away). Too late to try now LOL.

From what I have read about this unit, if it is the right unit, it could be a broken mode fork or planetary. I only hope greasemark has a way to disprove your theory, as I am now (after hearing your opinion and seeing what isn’t wrong inside the transmission) more incline to agree.


But I still do not understand the grinding from the bell housing area of the transmission, were this the transfer case would it not grind from there?

 

Well there is one thing you can be sure of, nobody else is going to take this job away from you, now doesn't that make you feel better?
Noise can travel and the bell housing could be like a guitar, hollow on the inside and amplifying the sound as if it were coming from the front.
That last statement is typical of ,"If you can't dazzle them with brilliance, baffle them with bullsh--".
It's not a case of who is right or wrong just trying to look at as many of the angles as possible and coming up with a reasonable solution.
Did you by any chance try to rotate the input to the transfer case assy and see if there was any kind of resistance or movement at the case output?
We have every confidence in your expertise so don't go gettin soft onus.
Just think, at least 50 more times like this and you might catch up to my mistakes.
And who is to say this is not another one of them?

 

Can I say no here?

The more I learn the functionality of a transfer case the more I wish to turn back the hands of time and kick my _ss for not thinking of it. I have always told my kids the everyday you don’t learn something is a wasted day (don’t remember where I heard that but everyone knows it). Looks like I learned a big lesson on this one.
Oh well, I’m not feeling bad about it, even if it does turn out to be the transfer case, as burnt as the fluids were in the transmission, I would have recommended new frictions and steels anyway, so the teardown is not in vain (making myself feel better, don’t bust my bubble).

 

Ya never know, it aint over till the fat lady sings !
When you get the chance to confirm what you suspect, you will hear the singing in the background. lol

 

I hope y'all have the best of luck on this mostly to you Richard as for me I've my own problems that have to be dealt with if you know what I mean
