A cooler trans would translate to less heat getting to the motor :-D, also since power steering is brought into the subject on 6.25 I figure the trans cooling could be argued.

In spec miata there is a concept of a "weenie protest", a protest for something that doesn't help performance, for example there were guys welding and reinforcing up the diff housings since they frequently broke, they eventually passed a rule for it but no one would really protest because it would be a "weenie protest".

A trans cooler would actually hurt performance because the cooler fluid would be more HP robbing.
