Yes. I'm guessing you do not have a solar filter for it already since you are asking. Typically a "white light" filter made of mylar or coated glass is used (http://www.kendrickastro.com/astro/solarfilters.html).
If you are hoping to observe the transit today, you'll need to setup to do a solar projection. The following link has a few pictures to give you an idea on how to do it. http://www.skyandtelescope.com/observing/objects/sun/Viewing_the_Sun_Safely.html?showAll=y
Do not, under any circumstances, look into the telescope or finderscope without a proper filter. It could cause major damage to your eyes!!
