Might have asked this before, but is it possible to buy replacements for the drain plugs to the main transmission and / or transfer case that enable fluids to be pumped in with the plug replacements in place, then closed off? I'm thinking of plugs either with brake caliper like bleed nipples or iddy-biddy spigots built in.

I can't get at the transfer case fill plug, it's blocked off by the parking brake drum, and filling the transmission while the engine was running proved to be a disaster. I ended up wearing more ATF than got into the transmission pan!

On another point, should I use smears (smears, not bucket-fulls) of instant gasket type stuff on the rubber transmission pan gasket?

Thanks.

 

To get at the transfer case fill plug... there is a huge wiring harness in the way. Try to move the harness aside.... use a 1/2" ratchet socket (no need to use extension joint).... and plug the ratchet directly to the transfer case plug.

 

^ Tried that, couldn't get the harness out of the way, and the plug as it sits is at precisely the wrong angle to get a breaker bar into.

Someone else suggested removing the level sensor or something from further up on the side of the transfer case and filling through that hole but I'm looking for an easier solution, especially for the main transmission. This is mostly used as a "Chelsea tractor" with "off road" limited to the garden center parking lot, so I'm not too worried about knocking off the spigot on a rock or something as I traverse the Himalayas...

Thanks anyway.

 

It's not a wire harness, it's the e-brake cable. Use a socked directly on it

 

^ Like I said, can't budge it. Maybe it's down to how the particular person that assembled the Disco in question fitted it....

 

use a 1/2" wobble extension to get in there.

 

Okay. Look. I've tried every combination of socket, sonic screwdriver, Ouija board, you name it. I cannot get that plug out without removing the brake drum and / or cable. Period. That's WHY I'm asking about drain plugs.

Thanks again...

 

I should add "She" had the tranny rebuilt a while back and maybe the parking brake cable didn't get put back 100% right and now sits RIGHT over the drain plug.

And that still leaves the main tranny refill to deal with.

 

We use a type of fitting to fill the coolant system on IC Maxforce diesel engine. Because of the ER coolers, and to avoid any air pockets, anti freeze has to be forced into the system from the bottom of radiator. Did a quick Internet search for a picture of one...but came up empty. Cat also uses the same type of connection/plug for checking fuel pressure at filter housing (C7).

The fitting somewhat looks and works in the same fashion as a air hose quick connect.

Not sure how receptive this fitting would be to 80/90 weight oil. It would probably take a bit of strength to move that type of fluid through it, but trans fluid would't be an issue. I'll try and snag one from work tomorrow and post a picture (which is worth a thous...eerrr...a million words...with inflation and all...lol)

This is the fill portion (female) of the quick connect, can't find picture of male fitting. Almost seems as though some sort of sexist is going on... female fittings, but no male ones...lol.

There are probably cheaper alternatives.
