Transfer case question

Just a quick one, if I run the engine with the transfer case off, will transmission fluid leak out.

Thanks

Care to explain?

OP - not likely - especially if the tranny is in neutral and its seal is good.

Lookie here, no leak

Depends on your transmission. Fill in your profile

I had no issue with the AX-5 leaking fluid when the transfer case was removed for 3 months. I never did run the engine though.

Hey Joe! Sorry, but you're all wet on this one!

The input shaft of the transfer case seals up to the transmission rear seal.

Yes, it will leak fluid if you run the engine without the transfer case installed.

No, it doesn't. ALL of the transfer cases seal the rear transmission seals of all YJ transmissions the same exact way.

Guess ya learn something new every day. I didn't leak a drop of my ax15 when I pulled the transfer case off and started it in neutral. Perhaps I was either lucky or just really low on oil.

I wouldn't ever argue with Max. Where the heck ya been, man?

If the transmission is not level, all of the fluid will come pouring out of the back when you remove the transfer case. I have taken a 5w30 shower in the past.

In N, just the input shaft would be spinning so its believable that you would not be leaking out of the trans. With the clutch pedal pressed would be the best bet to not loose any fluid as nothing is spinning.

Mean Max is correct the counter shaft will also spin and with no load on the output shaft, it will spin too. I'm in the process of rebuilding my AX-5 and I confirmed this last night. Sorry for the confusion.

Not all accurate. The input shaft would indeed be spinning, but so would the counter shaft, and with nothing to keep it from spinning the output shaft would in fact be spinning in neutral from the viscous properties of the oil in the transmission.
