231 Transfer Case Questions

[B1Toad]

Getting ready to pull the transmission for clutch fork work and I drained the transfer case and found dark fluid, either motor oil or light gear oil. Definitely not dark automatic transmission fluid, I know what that smells/feels like. Whatever it is it is somewhat fresh as everything was gone thru 13,000 miles ago. It doesn't have the nasty gear oil smell and it feels like a synthetic motor oil. I have some NAPA Merc/Dex which I will use to flush it out and replace. Hopefully no damage has occurred. Should I rinse first with kerosene or just flush with ATF then change again soon?

Also the vent nipple on top had no hose attached, where is the transfer case vent supposed to terminate?

I'd just drain it, fill with ATF and call it good. A little bit of motor oil in there isn't gonna hurt a thing.

I believe the vent runs forward up the passenger side of the tunnel and up the firewall.

Yeah there's posts all over the Internet about what secret sauce to run in your 231. ATF is the recommended fluid and it's what I use. Sounds like your PO drank the Kool Aid.

Vent terminates up near the brake booster. You can follow the master slave clutch cable. I can look up the Dorman part number for the one way valve if you need it.

And if you've come this far consider a SYE and a cable shifter.

I was going to build a vent line with fuel line and terminate it with this: https://www.amazon.com/gp/product/B009XZRLZA/?tag=wranglerorg-20

I also have the Savvy cable shifter arriving this week. What's a SYE? Slip yoke eliminator? Do I need that if I'm stock height?

Do I need that if I'm stock height?

Nope. Just encouraging everyone"s eventual migration to 35s.

Since the primary use for my Jeep is a toad I have no plans for 35's, 31's is a big as I'll ever want or need.

I know I know....been there done that but in my old age I've wanted to keep everything stock. When I wanted 18's on my 2002 Superduty I searched out a set of OEM Lariat wheels, they cost me a lot more than after market but they are hub centric and made for the truck, and look great. 5 vehicles presently all pretty much stock and in a near perfect condition as possible.
