A new goody for our trannys?

Hey you guys,
My car has been in the shop for a very long time due to the fact I have the best mechanic in the entire world! He is soooo through because he has fallen in love with my car and is now in the market for one.

Meanwhile as he is doing his final 200 point inspection (I am slowly restoring the entire car because of the idiots at my local Subaru store destroying my baby) He noticed the aftermarket tranny cooler. He is very observant, upon his test drive he noticed the gearing and the weight of the car. He gave that some thought and called me after some research. He asked me if I would mind him replacing the Tranny cooler? (after spending serval thousand dollars there this visit he even offered to pay for the new cooler and labor himself) But anyway, this new cooler is a heavy duty cooler that has a built in electrical fan... This sounds like just the thing for our cars. Any input would be welcome! I would love to be a guinnie pig if you guys think it is a good idea!
