Upshifting dilemma

[scooby151]

Hi all, today I drove my car for the first time since installing another engine. I would like to ask if anyone e has had a similar 'problem' to me. When upshifting , there is practically no feel or feedback through the gearstick that the gear has actually engaged, even though it has. My other engine did give some sort of resistance when upshifting. However when downshifting, there seems to be more feedback than up shifts. Any idea?
Cheers boys

Hi, thanks for the reply. As far as I know , everything is as was in the previous engine. I was told in the meantime, that it is doing this because gears are undercut. No idea though.
Cheers
