Gear box feels like shifting in sand

Cbtech

So i just got a new long block under warranty from the dealer and i put in a south bend stage 2 clutch in her with a Z1 HD CSC. Had a few issues with the CSC not bleeding correctly but finally got it resolved. Now im running into an issue with shifting. The clutch engages and disengages without issue but when shifting into ANY gear it feels like im having to push harder into each gear. There is no binding, no grinding, or slipping but for lack of a better description it feels like im shifting in sand. it almost feels as though something is over tightened but i pulled apart the shifter and shifter plate and found nothing binding there. Has anyone run into this issue before? Im thinking that they may have forgotten to fill the transmission back up with fluid but i wouldnt think that would be the issue. I didnt have this issue before the car went in for the long block install. only thing new is the CSC and the clutch as far as the transmission is concern. thanks for your help!
