Yep, happened to me. Brand new transfer case that must need some stick adjustment, kept popping out of low. On one very steep hill where my brakes weren't even holding, I had Jeri try to hold it in low, but she couldn't. J Mack seeing a problem ran down the hill and jumped in, but little did he know, Jeri had just put on some hand lotion and it was on the stick. J Mack being who he is, said he didn't mind as his hands could use it since he doesn't have soft hands.

Well, we got up the hill just fine and Jim grabs a ratchet strap and locks the low range stick down, so for the rest of the trail it stayed put.
Back at camp Jim was commenting on how nice his hands felt, so I sent him a link to Jeri's lotion.
