GENUINE Tru-Cool 40k Transmission Coolers!

NEW part number for 2024: 35-72172-00
OLD part number: LPD47391
There are a TON of knockoffs floating around there for half price. These are not genuine and if you read reviews, they are not the kind of quality you’re expecting from Long Manufacturing / Dana Corporation. 

Available with optional 6AN or 8AN adapter fittings, that actually FIT. We have tried several manufacturer’s fittings and finally found some that don’t bottom out before sealing. 

***NOT ALL PARTS ARE MADE THE SAME DESPITE THE PRICE POINT BEING LOWER***

We also have cooler manifolds for 6L80/90, 8L90, 10L80/90, and 6R80/10R80.
