Transmission Fluid

[thomash85715]

Our 06 limited with automatic n overdrive behind 3.7 V6 suddenly left a puddle in the carport. It shifts fine and nobody has worked on it in some time. It has suddenly gotten ambiently hotter here in AZ after a mild spring but otherwise no reason this might suddenly show LOTS more fluid on the stick than is called for. Wondering if anyone has ever seen a blockage in the cooler lines to the radiator that might cause the fluid to show higher. It has been weeks since we looked on the stick since there have been no signs of leaks and no misbehaviour of the operation. Also not clear where the venting of the fluid came from. It does not appear to have burped out the filler dipstick tube. Is there an emergency vent underneath somewhere? Thank you.
