If you have a shudder when taking off, I'd bet you didn't properly prep the flywheel/pressure plate. They are coated with a parafin wax to prevent corrosion during storage. You should clean it with brake cleaner, then lightly scuff it to ensure it is wax/oil free. You likely have hardened spots on your flywheel/pressure plate. Hopefully it will bed in. A transfer case going bad would not present with a shudder, although a carrier bearing would. My money is on a warped/heat checked flywheel considering you just did a clutch. You have to be meticulous breaking them in.

If it is the clutch chattering, you can slip it for 10-15 seconds to bed it into the flywheel. As bad as it sounds, I've done it quite a few times.

i put new clutch, throw out, pilot bearing, and got the flywheel resurfaced. one thing i didnt do is wipe the fly wheel or the pressure plate down, i know stupid of me guess i was a little exited to get my new clutch in. . i tried slipping it like you said and it seemed to help some but i still got some shudder not as bad though.
