Tranny fluid mystery bolts???

thanks guys, I will be try to be more helpful and post pictures tonight

on the transfer case the fill and drain bolts are circular with a square hole, you just stick the end of your 3/8" socket wrench in there (makes it easier if you use an extension) in there instead of putting a socket on the end of the ratchet

alright skilled mechanics and great knowers of all things, what the heck are these things and how do I get them off so I can do a transmission fluid change???

I don't even know what to think about that...does an allen wrench fit them?

I would have some stock ones on hand before I thought about vice gripping, or pipe wrenching them out...maybe they were stripped by the previous owner?...or a transmission shop?...
Anyone recognize these as a "quick fix" someone might have done???

Yikes.

?????zooming in, it does look like the holes are "hex-ish"
im with lub, i would have on hand the plugs that are SUPPOSED to be in there.
side thought, there must be a tool that takes advantage of that hole in the center, like visegrips, with a pin for the center, to keep the grips from comming off. ya got me???

maybe take your pics to a snap on tool, or mac, and see what they say. they might have a tool??

Um so those things are NOT stock? That is what I have.

Well good, I feel better that I'm not the ONLY one who has something goofy like this going on underneath my VX.
I will fiddle with it more tomorrow to see if anything I have will fit that small hole. I have to wonder what benefit this contraption is over OEM. If anybody knows anything else on this, please chime in. Thanks!!

Mine has never been serviced and those are what are on mine.

They could have run into a supply issue at the factory where the 4L30E is made, & had to find an alternate source of plugs.
Could also be an improved design, to lessen the chance of over tightening & stripping the threads?
