Quick random question. Does the transfer case in the Blazers with the auto 4wd button suffer the common issue of fluid getting pass the seal and sucking up into the vacuum lines, or is that only an issue with the non auto option transfer cases?

I would only assume that the transfer cases are different between the two, but is the problem common between both?

I only ask because I could have sworn I read it somewhere that it's not an issue if you have the auto 4wd but I cannot dig it up anywhere again... I'm not having issues with mine, I have an 04 with the auto option, I'm just curious.

Thanks
