Not many updates lately. Got frustrated and didn't touch it for 6+ months.

Took a course on Manual Transmissions, Axles and Transfer Cases at the local community college. Was a cool experience. Got to put the suburban on a rack and run it safely to look for issues. Instructor agreed the issue seems to be in the transmission or transfer case.

Sooo....
I ordered up a NV4500 and 241 transfer case today. $$$$$! However I'm at the point where I just want to throw money at it to get it to a point that its driveable. Hopefully that will give me smooth shifting, overdrive, and cure my vibration issues.

Its going to be a PITA project. Shifter will be in a different location. Will require a different transfer case shifter. Going to convert to hydraulic clutch at the same time. Will require new driveshafts (again). My new exhaust will likely need modified. The trans/case should arrive in 2-3 weeks, so expect more updates then.
