The IRAM Large Program consisting of observing the CO(2-1) transition in the Triangulum galaxy M33 is now over. This very sensitive survey covered the disk of the galaxy up to 8 kpc. Here we present the results and the techniques used in the data reduction process as well as the integrated intensity map. We determined that the velocity dispersion between molecular and atomic gas is very low. Whith this dataset, molecular cloud detection algorithm were also able to found more than 500 giant molecular clouds.
