Can some one post a pick of the user guide for the np205 or provide some instructions. At what speeds is it safe to shift?

its not a shift on the fly tcase .
but if you have a good lubed tcase linkage system and know your truck you can float the 2wd to 4wd high portions. this is off the throttle and coasting.
the rest like ( n ) and 4wd low will require stoped and foot on brake and tranny in ( n ) also
there is a grease fitting on the shifter piviot or bolt that need to be greased at some times and also use a good lube on the shift linkage and rails were thay go in the tcase. if this stuff is to dry it will bind up bad and feel like it wont move.

This is probably obvious to most people, but I'm gonna say it anyway just in case--you can float the 2Hi to 4Hi at any speed as long as your front hubs are engaged 
Other than that, what sweetk30 said.

X2, I float my 205 between 4hi and 2hi during the snowstorms while cruising down the freeway. I usually wait until I am certain it is safe for 2hi and then let off the gas and float out of 4hi. Never had a problem, other than the one time I accidentally floated into N at 45.

Even my twin-sticked NP205 works like that - between rwd hi and 4wd hi or frtwd hi and 4wd hi and vice versa - ok, not as smooth as my old 208 but definately without grinding noises.

Yep do the same with my twin stick.
I drove my buddy's rig with a doubler and could shift from 2 low to 2 high at 40 mph, you have to remember to shift the trans into N and be quick about the t-case shifting but i was able to do it without any grinding (not sure if it had anything to do with having the doubler though).
Depending on the original application of the 205 it could be syncronized which, of course, would make shift at speed a snap.
Nope, it wasn't a syncronized 205 i know this for a fact since i was inside of the t-case.
to the OP 
how do i know if my np205 was syncronized?

ok, im about to ask probably the stupidest question ever in the history of this site, but i need to know for sure. do i drive my k5 transfer case shifted in neutral or in 2hi? its an np205. this is my first 4x4 so take it easy on me fellas lol!!!!
You leave the t-case in 2hi for daily driving.
If you leave it in neutral, the truck won't move at all.

Neutral... ALWAYS drive in neutral...
Just kidding, man... You'll want to be in 2-High for most street driving. Keep the front hubs unlocked for best gas mileage and less wear and tear on the front axle.

thanks for the quick responses , and the little bit of humor, when you put it like that jon i can see how stupid the question really is lol!!!
No... The only stupid question is the one not asked.
If someone was unsure how a transfer case worked, they could, in fact, possibly think that running it in neutral would be to keep it "out of the loop", so to speak... So, no... your question was NOT stupid.
Can I hi-jack and ask another stupid questions. I'm not familiar with 80's auto locking hubs. I re-call something about reverse to lock or un-lock, so how do I lock and unlock these hubs correctly. Sorry for the hi jack.

The owners manual says shift to 2wd, wheels pointed strait, backup the length of the vehicle. If there is any bind on the front axle (like being in 4wd on dry pavement) the auto hubs have atendancy to stay engaged
