if CMH-DTW isn’t mainline service, you’re likely to arrive into the B gates; combined with having to wait for any pink-tagged carry-on bags, this adds ~10 minutes to your transit time
it certainly can’t hurt to ask DL if they can accommodate you on a different flight because you’re not comfortable with this 37 minutes, but I don’t think they’re obligated to do anything unless published MCT at DTW is 40 minutes
