acura 2.3 CL

I recently got the clutch for my 98 2.3 CL (manual transmission) replaced as it had been worn out. After fixing it, the shifting from one gear to the next seems to be really stiff. It used to glide from gear to gear, but now as I attempt to switch gears, I have to push it much harder to get it to lock in. What should I do to make it smoother? The mechanic who replaced the clutch kit for me said that I have to get some kind of oil sprayed on the bottom of my car...? He didn't speak very good english and so I couldn't figure out what he meant. He said they don't have that facility at his shop , but I wanted to know what I am supposed to be looking for.
Thanks

you need to take it back to the shop, cluth disc improperly adjusted cable,or linkage.
