Hey Guys! Its good to be a member. I'm new here and have a question already. I've been researching trans pans for my Allison tranny and I'm not sure which route to go. ATS offers a deep pan that claims to hold 5 additional qts of fluid for proclaimed cooling and longevity of fluid between services, but I don't think it was manufactured with the internal fluid channels like the PPE. Now, that being said, I found the PPE design, construction, and price to be substantially better than the ATS pan, yet the PPE pan only holds a proclaimed 4 additional qts of fluid as opposed to the ATS's 5 qts. So, my question is, which pan is more efficient at cooling? Do the internal fluid channels of the PPE out weigh the benefits of ATS's additional 1 qt capacity? Interested in facts from engineers/technicians and opinions from the experinced... Tx!
