Input on deep transmission pans, I'm in the process of a built transmission and I want to keep it cool as possible. I understand the concept of more fluid and cooling properties because of it. My question is with the PPE and ATS with the cooling fins,is it beneficial enough to spend the additional 160 dollars give or take vs a deep Allison pan? I'm not looking for the cheap way out just curious on temperature differences with or without fins? PPE advertises "as much as" a 40 degree reduction. Thanks in advance!
