I am guessing this is the fill opening for the manual transmission.

My confusion stims from reading that these two items share the gear oil so if i fill the transfer case from that opening mid line on the trans mission wont oil come out. If im not mistaken i think that is where i drained the transmission from... so where in heaven name do i fill the transmission?

Also can someone confirm the gear oil fluid capacity... thanks

Do i do it from the transfer case? Kinda wondering what was mitsubishi thinking when the built this guy. I could not find much info so i thought id ask the gurus here. I tried downloading the manual from the site but the file is corrupted so i thought id ask here before buying a manual to see what the heck to do. Thanks all.

This is a 1987 mT 4x4

The manual lists the transmission as 2.2 liters and transfer case as 2.2 liters and both as 75w-85. I used 80w-90 in mine. filled until it was coming out of the transfer case and then filled transmission the same. From what I can see in the manual, they are sealed separately. You have identified the correct fill plugs.

This looks complicated, I'd rather rebuild a 46RE or TH350/400 than do anything but change fluids on the KM145.

Lol thanks for the info!! Yeah it's a mess!

Confirmed those are the correct fill plugs. Oil level should just reach the bottom of the hole for each fill plug, so the hole/plug position midway in the side of the case ensures they cannot be overfilled.

Drain plug for the trans is in the middle of the sump pan (bottom-center of your photo). Drain plug for the transfer case is on the bottom of the case, just beyond the bottom-left corner of your photo there.

NOTE: Do not use GL-5 rated gear oil in the transmission. The owner's manual states "GL-4 or higher", but that was published before the GL-5 spec was established requiring extreme-pressure (EP) additives that don't play nice with older-design syncros with yellow-metal (brass/bronze) components, too slippery for proper syncro engagement and corrosive to copper-based alloys. I like Redline synthetic gear oils; their MT-85 manual trans oil should be good for moderate-climate Virginia (MTL for colder climates, MT-90 for hot climates).

Hi All thanks so much.. I will need to double check that I did not put in GL5, I am sure that I did not but now you have me guessing...
Any ways I have another question.. today I took the truck out after doing the maintained as well as some upgrades... it was its first drive as I had to take the truck in to the exhaust shoppe to get the exhaust connected to the headers and man what A disaster.

I have some sort of jet black fluid dripping... well pouring out of some where from the top of the motor. As I was driving home I notice smoke coming from under the truck. This is dude to some sort of oil that is coming from somewhere. I believe it is coming from up top as it is dripping down both sides of the transmission bell and onto the ground.

I have brought the truck home and de-greased the bell and the back of the motor and washed it all down. I will put the truck on the lift tomorrow to see what the heck I have done to my lil truck.

Here is what I did this maintenance cycle as it relates to this issue

New valve cover gasket, I did not know the torque numbers so I put it on tight but I could not find how tight. But not leaks that I can see there
New fresh Oil Changes ( I used Syth Blend, 6 quarts)
New Fresh Fear Gear Oils Trans, Diff and Transfer Case
And Headers

What I have noticed

No Oil Coming from the Value Cover or PCV
Whatever is leaking is pitched black and I am losing alot of it very quickly
Some of the Oil or whatever is dripping on the header collector.

It is some type of oil from somewhere.

With everything being fresh I am shocked that it is black like spent oil
I don't recall anything on the stick exhaust manifold that had anything to do with stopping oil.

My Big question... did I break something by driving the truck over to the exhaust shop without exhaust pipe and muffler connected??
Due the lack of back pressure..

Did I overfill the Transmission

Did a seal or something go because the truck is bleeding something pitch black which I suspect is bunt oil.
I will have wait until daylight to get a better look at things as I was too disappointed in the situation to do anything tonight with it.

Thanks all, I will add more pictures tomorrow once I have the truck on the lif.

Did you remember the half-moon seal? :grinno:

I did but you know .. i am going to get my mirror and check because it might be miss aligned... Thank you..

6 quarts is way too much oil - 4.25 to 4.5 quarts is all the 2.6 engine takes.

Haynes says oil capacity is 6.1 qts for 2.6 for 4WD truck.
