I just replaced the transmission in my 98 s 10. Also put new clutch pressure plate and throwout bearing in while I had it tore apart. Problem is in third, fourth, and fifth gear truck has a slight shake. Gears 1 and 2 are fine though. The shake is much worse when accelerating or giving the truck gas, not too bad when just coasting or rolling downhill. Also hear a spinning sound when clutch is out, but when you push the clutch in it quits. Everyone tells me throwout bearing but it is brand new. Pretty simple to install, dont think I screwed it up unless I missed something. Are you supposed to bleed the new clutch? Any help appreciated

Is this the reason you changed the transmission? Is the transmission new--rebuilt--or from the junk yard?
Did you use an alignment tool with the new clutch?
Did you have the flywheel resurfaced or at least checked before installing the new clutch?

Yes used alignment tool to do clutch flywheel was said to be ok. Transmission is used supposed to have only 5000 miles. Truck shifts smooth though so I hope its not transmission.

A flywheel after 180000 miles should at least be checked for proper thickness and resurfaced so the new clutch works properly. Yes, it must be removed to check it. I would just replace it. But even a new one needs to be properly surfaced--just like a brake rotor.
Before you go removing the transmission again try bleeding the clutch system. The bleed screw is located on the left side of the transmission, and the system is bled just like the brakes, using the clutch pedal of course. This may be the cause of the spinning noise. If the throw out bearing is not releasing all the way it may be putting pressure on the pressure plate causing a vibration at high speeds. If this doesn't cure the problem then the problem sounds like either a worn out thrust washer, or washers, inside of the transmission--or--a warped flywheel.

High speed only issue makes me think your drive shaft somehow got out of balance when it was re-installed. If it were anything else but that the shaking problem would happen in the lower gears as well. The only time the drive shaft spins at high speeds is when you are driving in 3rd, 4th, 5th gears. I'm betting your drive line is out of balance for some reason.
