Hi, all. I was about to do a transfer case fluid change on my 2002 Envoy. This is a used truck, and I've only had it a few months. I hadn't wanted to drive it much until I had done a transfer case fluid change.
Well, I jacked up the truck, undid the drain plug, and only after I had drained the fluid did I realize that the fill plug was completely seized into its hole! I thought that I had gotten it loose, but it turned out that it was my 10mm hex key socket spinning inside the socket on the plug!!! Now, I managed to get at least a litre of fluid into the TC by running a small air hose up through the drain hole as high in the TC as I could, then wrapped my oil transfer pump tube in a rag to seal the hole, then pumped in fluid. I measured what spilled out when I quickly removed the rag and put the drain plug back on, so I am confident that there is fluid in there.
My question is, now what do I do? I could take it to a shop if I have to, but are there any suggestions on how to get this thing out? I can't drill out the bolt, since there isn't enough room to get a drill behind it (and even if I could, I would be worried about getting chips inside the TC.) I had sprayed some liquid wrench on the plug, but it didn't make much of a difference. Will the shop even be able to get it out?
Thanks,
-Chris
