It would be nice, but not really needed IMHO. Unless you're pushing some serious power, in which case, the temps won't even matter, cuz the tranny will die anyways from the torque. The radiator does a fine job of keeping the trans temps well below 110C. There's a guy whose tranny failed and they pulled the data from the life time of the trans, and even at the track, the trans temps were 110C for an hour, at the nurburgring, but never over.
