Converter/ Trans Shield Leak

After moving a heavy trailer (12-14K) I noticed that the shield that covers the converter on the front of the transmission has a little bit of a leak. It does not appear to be a constant leak and both the engine and trans have normal amounts of oil showing on the dip sticks as well. Wondering if this is something to expect when moving very heavy trailers or if this is a sign of a problem? If it helps, we first noticed this after backing it over a curb. I brought the rpm's up on the truck just a little to help get the tires up on the curb. Just looking to see your thoughts on this .... Truck still drives, boosts, and shifts like it normally does .... No extra engine temp and don't have a trans temp gauge so I can't give any other information there.

Thanks guys!

Backing up over a curb with a heavy trailer is about the best way to overheat the torque converter. When it gets really hot the torque converter hub seal gets soft and leaks. Almost always it seals again once it cools off. If it stops leaking that's probably what happened.
