Tranmission transfer case

[aaklingler]

Is the E4od and transfer case supposed to share fluid? Is it going to cause trouble if they do?
Thanks

They don't on the ZF's so I wouldn't imagine they are supposed to in the E4OD either.

I do believe they use the same type of fluid. I do not believe fluid is supposed to flow between the two.

No they should be separate systems, no sharing of the fluid.

Does it cause problems when they do share?

yes it will drain transmission and fill transfercase until it comes out overflow. NO SWAPING OF FLUIDS!!!

The seal should be replaced ASAP if this is going on. To much fluid in the transfer case will cause it to fail.

there will be sharing of fluid between the transfer case and trans. the gasket is only to keep fluid from leaking out of the tail section and transfer case. the transfer case can accept fluid but not much as the fill port between the TC and trans is quite high at the top. plus the area of the parking gear is not filled with atf. they take the same fluid the trans and TC do.

now if its filling the transfer case then you have other problems and need to examine the seal around the input shaft of the TC.
