1996 Yukon 4WD 5.7l with NP243C transfer case.
I removed the driveshaft to change u-joints.
While I was working, about 3/4 quart of ATF dripped out of the transfer case.
I reinstalled the driveshaft.
Then I removed the 30mm top fill plug on the transfer case, to top off the transfer case.
However, as I unscrewed the (top) fill plug by hand, fluid came gushing out like it was over-filled.
I'm trying to figure this out.
I drove 20 miles and then checked the transmission fluid level with engine running. It was right at the top of the hot range.
Does the transfer case share atf with the transmission?
If nearly a quart of atf dripped out of my transfer case while the driveshaft was pulled, then why is the transfer case "overfilled" after I put everything back together?
Any ideas?
Thanks.
