Ok I think i might have a big problem. Ill start from the beginning. Found a tranny on craigslist apparently for a 2000-2004 4x4 6.0 truck. Here is the link...http://grandrapids.craigslist.org/pts/2787914866.html

anyway i bought that tranny and now im startin to think twice that its not the right one. only a few of my harness connectors match up to it. the part number on the case is gm PN 24208421 and when i search it on forums it looks like its for a van. does that mean its for 2wd only? because my truck is going to be 6.0/4l80e/ 4WD. Do you think thats why some of the connectors dont match up? its a really confusing story but my 6.0 and harness was out of a 2005 2WD truck, but i was told it all would work for my 4WD application, i would just need a 4x4 trans....hmmmm......yes my brain is in a pretzel right now.
