Yes. It can be done. You need to have the tools to drill and tap the fill plugs. After that it's just a matter of sourcing the appropriate elbow fittings and hose. If you have the tools, and ready access to the appropriate parts, it's prolly less than $20.

I didn't have the tools, so bought the kit. Easy install...maybe 30 minutes including washing my hands aferwords.
 
What is this thing for? I think its to equalise the oil between the two. What models would need it? I have a 2000 troopie but I dont know that it has an oil problem there. How did you find out you did?

Take out the transmission fill plug...if fluid comes pouring out then the seal between the tranny and the T-case is not doing it's job. The T-case is pumping fluid into the transmission. The kit allows the excess fluid to drain back into the T-case. Factoring in my time, I decided to go with the kit. Easy install...just don't use hose clamps.:doh:

I built my own kit for just a few dollars by tapping the fill plugs and using an assortment of brass junk from Home Depot. El Cheapo!

As long as you have the drills and the taps. If you do not have the necessary tools, it gets a lot more expensive. '
 
Hey Guys thanks for the links and quick feedback I think I might tap the plugs I have access to a pretty good shop here on base
 
Opposite problem

What if the transfer case has the excessive oil? I have an '83 4-speed and figured my seal was bad allowing gravity to fill the transfercase with transmission oil. Any quick fixes?
 
same thing..

What Mace said. Just may have to overfill the transfer (its fill plug is lower) so that your tranny retains an adequate level.

I paid a local mechanic $15 to do the drilling and tapping. The whole deal cost about $20.
 
Having not yet gotten to that part of the prep job, what are the drain plug threads? Might be possible to just buy the right AN adapter and not have to thread anything.

That is what I did! Take a plug into somewhere that deals in hydralics and they likely will have the right adaptors. I paid about $20 for mine doing it that way and when I tear down the transfer and fix it I still have good plugs!!
 
I have the tap at home. Let me check tonight (if I remember lol)
 
From this place: BRASS FITTINGS Brass Pipe Fittings Hose Barbs Stainless Steel Fittings Hydraulic Adapters Hydraulic Fittings Grease Zerks Hose Clamps

I bought 2 each of:

Part Number: JF-90-8-8 Push Lock Hose Barbs (Steel):<BR>Push Lock Hose To 90° Female JIC (Swivel)
Part Number: 816MM-8-18 Metric Fittings: Male JIC To Male Metric

Then I visited a local hose shop and bought a few feet of hose recommended by them for the fittings.

Their prices have about doubled since I did this in May 2004, so the cost is now comparable to MAF's $55. Maybe you can find fittings cheaper elsewhere. With these fittings, no drilling or tapping is necessary.
