Default clutch going out or trans slipping?

So if i ease on throttle it goes but if i stab it / WOT the engine revs up like it has no load and then it eventually catches...sounds like clutch is out to me but i just changed transmissions an something is up i think..could the transmission itself slip like that or would that have to be the clutch just going out? havent smelld any burning clutch smells and this only started once i threw this "new" trans in..and usually in 2nd sometimes in 3rd when i shift into the gear i feel like a vibration that i want to say is coming from the driveshaft or yoke...guess ima pull my yoke off an check if there's any splines left..almost feels like my yoke is stripped out somehow maybe from the old trans but yeh any input? like could a transmission slip like that? hard to explain but hopefully u guys got the jist of it..I had a kinda older post with some back info if helps or anyone interested in my damn issues : )

Makes sense if it's a clutch issue, thats how they act when they're glazed over. A T5 can't slip like that.

well your clutch is the same principal as your brakes, and you know you want your pads to be rough so they grip better, same applies to your clutch disc. Glazed means they smooth out and create a shiney surface. Sand paper can fix the issue but I guess it would depend on how old the clutch is.

You will need to replace the clutch plate, pressure plate, pilot bearing and throw-out bearing.
You will also need to have your flywheel resurfaced by a machine shop.

There is nothing in a manual transmission that can "slip".
