broke my th350 today

[74huggerorange]

went wheeling at disney today and cracked the rear of my th350 case all the way around at about the rear of the pan. I have a np203 behind it...I have no idea when "exactly" I broke it or how I broke it....is it caused by the weight or something else?

Could be bad mounts, driveshafts too long, hit something...
