Hey All,

I have finally gotten back to my project after getting pulled in 50 different directions over the last month...my wife asked me what I wanted for Father's Day and I said how about 6-8 uninterrupted hours of wrenching?!

I got a tranny jack from Harbor Freight and as I got on the ground to pull everything, I said hmmmmm I really don't want to do this if I don't have to....I wonder if shifting the transfer case affects anything? I rebuilt the transfer case at the same time so yet another variable to contend with...

Well...I shifted it into 4w-lo and it acted like a completely different truck..throttle response, no slipping, etc...so I did a quick search and saw where someone installed their np208 shift lever upside down?! I ran out of daylight (yeah...it wasn't exactly 6-8 uninterrupted hours!) to check it but does this sound like a possibility?
