As a part of the new engine/trans/ fun and games, I decided to swap the differential lube. It's been in there since I've owned the coach, and probably since the 3.7 gears and Ragusa cover went on. So I picked up a couple of quarts of synthetic lube, drained what was in it (not overheated, no particles) and set about to refill it. It seems simple, except you have to invert the lube bottle to get the lube into the opening in the case. So, snip the tip, return the red plastic cap. Work the bottle into place, pop the cap, stuff the spout in the fill hole and squeeze away. First bottle's empty, drop it, pick up the red plastic cap and snap it back on the empty bottle, toss it aside for the trash when you're done, repeat. Just under two quarts, she's full to the fill hole. Pop the cap back on the bottle and drop it. Cap, where's the cap? There's one on the empty, where's the one for this bottle. Put a finger on the spout, turned it right side up, and set it on the slab while I replaced the fill plug. Searched high and wide for the red cap, it's nowhere to be seen. The slab is clean, just swept, the dam' cap is nowhere. Well, it gots to be SOMEwhere, where's left? Ain't but one possibility. Surely that soft plastic would simply squeeze out of the gears and shred to the bottom of the differential case? I'm gonna bet a thousand bucks it will do so without damage? Not gonna happen. Gasket ordered from Jimmy the K, ought to be here by Saturday. I'll drain into a clean container, pop the cover, and remove the frickin' cap. Reassemble, refill, and have some peace of mind. Murphy lives here? You betcha.

You sure both bottles had caps?
I’d run it and not sweat it.

Hey, we all have stupid attacks from time to time. You can get a pump for that gear lube. It screws on the top of the bottle. Makes it easy to not make that kind of mistake.

Dont feel to bad.....after struggling to put the timing cover back on (it just didnt want to go back on) having changed the gear/chain set and making it all the way to the front engine mount install....i realized that the oil slinger was sitting next to me on the ground instead of were it should be....so it all came appart again.
To make matters worse i know better than to not double check my install......

Johnny,
I don't think that will let you displace me from my place at the head of
the queue for the Rubber Hammer award!
While you've got the cover off, why don't you get a bung brazed into the
bottom of it so the next time you can just unscrew the cap -- like I've
done for the past several years.

IIRC, that's not really needed except to lubricate the fuel pump drive cam
-- I'd have just permanently removed the mechanical pump. But maybe I'm
thinking of the cam itself?

Hey, that "Rubber Hammer / Dumbass" award respects no age groups. It can
strike any of us, even if we keep our awareness at a high level.
But, there is much to be said for the exposure that older guys have
accumulated through the decades.
I like your suggestion of having it as a topic at a rally, somewhere,
sometime.

Years ago in the 50's and 60's we use to put all kinds of stuff in differentials when they started getting a gear whine. Cork and soft plastic were two of the things we used. The stuff would get ground up and the gear wine went away after a few hundred miles. It did not help on bearings. I would leave it and forget it.

I would try to fish it out if possible but i'm with Johnny here...i'd be up all night thinking about it even if the gears set could take it.

The good and the bad. It's a Ragusa cover, so the fill port is small and on the side where you can't see into it, nor is there room to pass forceps or anything else. Fishing around with a wire hook got no results. No need for a bung, it has two. One for a temp sensor, the other larger on the bottom for a drain. If the cap falls out when I drain it there's an end to it. Otherwise I'm with Rich - I would worry.

For goodness sake. You are obsessing about this. How hard could it be to just drain it, pull the cover off, and look for the cap. Clean it up, new gasket, put the cover back on, fill with fluid and get on with life. Its not like you have to pull the engine to do it. If this is the worst thing you have to do on your GMC, count yourself lucky. JMHO

Larry,
It is not that I don't respect your opinion, but when there is no drain plug feature, you get to crack the cover loose and hope your pan is large enough to catch what comes out wherever it decides to go. There is no clean way to drain either an automatic transmission or rear end. The only relief is that if the gasket was not damaged (and it was probably not in this case) there is no reason to replace it. That "Always use a New Gasket" thing was started by the people that sell gaskets.

Well, I didn't take offense and I screwed up in the first place  And I'm of your opinion. It will take all of maybe two hours if the gasket is glued on and has to be scraped. Since it's a Ragusa, it will drain easily into a clean gallon water bottle which I can cap - my other fool's move is kicking things over when I'm working under the coach.
For those of you who want a fun job in 95 degree weather, take a look at how the starter is replaced on a 2011 Chrysler Town n Country. There are three or four you tube tutorials. That's next Friday's chore if the new starter gets here next Thursday as promised. Actually, I think the heavy current contact in the solenoid is toasr based on the symptoms but the procedure is the same either way since the solenoid isn't removable with the starter mounted. Getting the cap out of the coach diff is a walk in the park by comparison.
I suggest Kim Weeks needs one more sign for the tables in Patterson, Genius, Liars, and Numbnuts. Or whatever appellation fits. It probably needs to be double the size of the other two.
