Drain and Fill Plugs?

[kawaboy13]

Where is the drain and fill plug on an NP231? I've looked and there's grease everywhere so I can't find it? Pics please! And also on the peougout transmission? Also is it common for this transmission to leak? Thanks

you need a haynes or a chilton manual...i guess for a cherokee..

 

I know they have a whole section on fluid and maintenance..

Clean it. It will make finding the plugs easier as well as finding where the the leaks are. :wrench:

Yeah, beat me to it.

Step One: Clean the transfer case, tranny, engine.

Step Two: The T/C drain and fill plugs are on the backside of the the T/C. Mine are brass(?) 30mm, bottom is drain, top is fill. Remove fill first, then remove drain, drain, replace drain, fill with Dex III or suitable ATF. Replace fill plug.

 

On the tranny the drain plug is at the rear of the tranny, just above the cross member. It's a 5/16" (or metric eqivalent) square plug drive. If you can't find the tool, you need to make one with a sacrificial 3/8" drive extension...grind it down on all four side to fit. The fill plug is about mid way on the passenger side...easier to see when it's clean.
