I'm almost positive that my 05 LLY is leaking coolant from the adapter plate between the engine and trans. I have done a lot of searching and found some conflicting information. All agree that the tranny and flywheel have to come out, (and in my case transfer case too) but from there I've seen people say only the bottom part of the oil pan, while others so the front diff has to come out so that the upper part of the oil pan can be removed as well. Which is correct? I'm also reading that there is an oil line to the turbo somewhere up on top that is attached to the adapter plate. I can't even see it I don't think, so how or when is that supposed to come off? Also any links to a DIY type write up or some pics? I'm trying to gather all of the gaskets etc that I will need before I tear it apart, so any advice is appreciated. Thanks!
