Yes and yes... The guy I bought it from was reputable and the gear lube looked good on the way out. My best intentions are to frame off my truck starting sometime this winter so when i have everything apart i was going to go through the tranny/transfer.
So far shifting has been great, 5 gear is Awesome! I drove to boulder and stayed around 60 and it was so *hush* quiet in the truck it was pretty cool, even without the carpet and OEM floor mat. I can't wait to hear it when I put the mat back in!. Also, with replacing the driveshafts with ones with better u joints and making sure all of the driveshaft bolts were tight, the vibration level is much better.
I did post a few questions in the tech section about a few things I see going on and want to understand.
