Hi Scotty, I have a 2011 Kia Soul. Lately it's been making a groaning noise when accelerating (groan starts @ 1500 RPM and stops @ 2000ish) and it only happens when cold. Once it's warmed up, the noise goes away. Any idea what it could be?

pray it's not the transmission going out, do this video to find out if it's coming from there https://www.youtube.com/watch?v=pqh1oH8mEqY
