I bought a 00 with 165k on it and went to change the transfer case fluid and nothing came out. Time for a new case? Or is there hope? I don't know the maintenance history so I will assume it was original fluid and it all burnt up...?

Thanks,

John

There probably was a leak. You could try to fill it with tbe special mopar fluid (mobil 424) and see if it still works, but a good change that the progressive coupling is shot.
How is the Beetle treating you, just bought a 2.0 TSI DSG?

Hopefully that works. I put it up on stands and all 4 wheels turn in 4hi and 4lo.

Love the TDI. Great car, hopefully the HPFP doesnt blow like I keep reading about...

Not sure if by putting all 4 wheels in the air you can test the T case, because there is no real torque transfer.
You removed both the fill plug and drain plug and not a bit of fluid came out? Depending on how long the jeep was running like this, the T case bearings can be damaged. Also keep an eye on the fluid level, because there can be a leak.

Zero, zilch, nada.

I am baffled that it works, at all. I don't know enough about how this TC works to comment.

I completely get what you are saying, when we get more snow I am going to do more testing.

I have no idea how long, when I bought it 4lo worked, wasn't able ti accurately test 4hi.

In 4Lo the front propeller shaft is directly driven. In 4Hi a progressive coupling is used, which gradually can transfer torque to the front wheels, when a speed difference between rear and front propeller shaft exists.
Without fluid 4Hi could never have worked, since it uses a pump to actuate the clutch.

Amd driving this is the snow I noticed. I was fishtailing everywhere.

Lined it up in the driveway and mashed the gas while my wife watched and the fronts only rolled.

This seems relevant to my situation:

I'm dealing with the same issue too. The progressive coupler in the transfer case is shot. They go bad. Mine was never low on fluid it just quit working(I never abused it,really,...ok maybe a little.....or a lot;)). Something to consider is a 242HD swap(Google 247 to 242 swap).The progressive coupler is a very expensive part to replace.The great thing about the the 242 is you have the ability to lock the center diff in high range while also still retaining the all wheel drive mode. Something the 247 just cant do except in low range which is useless at highway speeds. My line of thinking is this:I'm not gonna spend $600 on a part(plus labor) to put in a t case with 75k on it. Rebuilding the whole thing is too expensive. I wouldn't think of buying a used 247 no matter what the mileage because your just asking for the same thing again.So to me my best option is buying a used 242 HD and matching rear drive shaft(You have to use the rear drive shaft from the donor WJ) for about $400 around here,throw a new chain and some seals in it,fill it up with nice cheap atf instead of that ridiculously over priced hydraulic oil and ride off into the sunset in 4 hi for somewhere around the $600 mark:D

I hear ya, that is the plan. Just gotta find one. Everyone says 02-03, but why not a 00-01 as well? I would think it should be a direct swap as I have a 00.

V8 select tracs were only made in '02 and '03. You don't want to use the light duty 6cyl version because the rear output shaft is too weak for the v8. My memory is pretty crappy but I think there's something different about the input shaft too because the 4.0 uses a completely different trans. Try Car-Part.com--Used Auto Parts Market for your area.You'll be surprised what you'll find.

According to Car Part there are 01-02 V8 selec tracs... Lots of confusing info on the forums. But I have found several instances where people have verified them to work.
