Cooler reduces temps and increases lube life. Eaton requires a cooler depending on engine hp and torque. But your probably out of warranty. Why would you want to remove it? Share some of the pros about eliminating the cooler. -
My issue is simple being a car hauler my ground clearance is so minimal that if I have to get under my truck for any reason I can’t without driving up on a set of 3 2x12’s to get enough clearance to shimmy under. Additionally have a coolant cooled cooler is running the risk of coolant into my tranny.
So eliminating one more set of coolant lines under the truck and removing the risk of coolant into the tranny.
I know I can go the air cooled route but i no idea what size i need, where to mount it to get best air flow with limited space. So Im sorta sitting on high center, etc.Last edited: Nov 28, 2023

Air to air coolers work well even without a fan. Keep them clean, mount then away from the exhaust and in a area with good air flow is best. Just out in the open is not bad.W923, Kozakvod, Big Road Skateboard and 1 other person Thank this. -

I put a air cooled trans cooler on a 378 we repowed for a customer about a year ago it mounted up front of the radiator got it from Midwest Peterbilt it was a aftermarket and it was kinda pricey
