I need to make a DCP from a 23.976 material. I have no trouble with the video but the last time I did the 0.1% time change to the audio I had lot of sync problems.
I finally went to some cinema sound-guy who told me the only solution to the problem was using some Pro-toole plug-in. So we did and it worked. It took like 8 hours to render the file, but it worked. This was a lot of trouble and expensive so I ask is there a way to do this in Audition?

I don't see why this wouldn't work -- other than that 24/23.976 is 1.(001) [meaning the .001 repeats, like 1.001001001001001), not 1.001 exactly, so your math is a little imprecise.

You don't have to do any of the conversion math yourself. If you import your 23.976 image sequence into Ae, then change its interpretation to 24.0 fps, its duration in the project panel will change. You can then simply put that duration into the Audition Stretch and Pitch effect -- just make sure that you are using the correct units for that duration (SMTPE 24 fps [Film])!
