How to know my transmission could be to change? (manual)?

Hi, i drive a honda civic 2006, i know my clutch is to change since i can hardly accelerate on any type of slope, small like big ones when going up a mountain. I tried going up a mountain and i rev up to red line and still took 10 sec to start going up and the 1st and 2nd gear are becoming hard to go in. But how do i know if one day i have to switch the transmission? Is there a way or i'm talking about the same thing and i'm just such a noob anyway thanks for the help

Clutch plate should go out any day now… Either that or it needs adjustment in the travel.About $600 when I had it done.

It would be MUCH cheaper to take you car to a shop of your choosing NOW and have the clutch replaced (your clutch is worn out), then to be towed to a shop and be at the mercy of the shop owner to do a good job replacing the clutch.
