That is not pressure it is overheated fluid, check the cooler lines for damage, if none found then the tranny cooler in the radiator, or just bypass the radiator all together with an auxiliary trans cooler, just make sure you get one that is big enough.

Make sure the transmission is not overfilled. Check the vent tube located at the top of the transmission, it may be clogged.
