-Real customer service you can call or text!
Features:
-5/8" flame and abrasion-resistant hose rated for 4000psi- SIGNIFICANTLY more than both OEM and built transmissions require
-Stainless JIC ORB fittings- no aluminum to corrode or crack
-Our own specific line lengths and fittings tailored specifically to each truck
Fitment notes: Please see pictures if you have additional questions:
-If you have an aftermarket radiator, you will need M22 fittings instead of OE-style to JIC. This can be easily determined if your radiator has a hex-shaped fitting BEHIND the OE-style transmission cooler fittings.
2001-2002 Allison transmission cooler inlet/outlet fittings had a smaller 3/4" thread diameter than later 7/8" units. If you think your transmission has been swapped with a later unit, you can measure the original trans cooler fitting in the transmission or reference the build plate found on the passenger-side of the transmission. If you need help identifying your fittings please contact us!
FLUIDYNE HEAVY DUTY BAR-PLATE TRANSMISSION COOLER
Up to 20° Lower Temps
Excessive heat is a major threat to your transmission’s longevity, leading to premature wear, reduced performance, and costly repairs. OEM transmission coolers often struggle to provide adequate heat dissipation, especially under demanding conditions, which can leave your transmission vulnerable. Upgrading to a more efficient cooling solution is essential to protect your transmission and enhance its durability.
The Fluidyne High Performance Bar and Plate Transmission Fluid Cooler is designed specifically for the 2011-2014 GM 6.6L Duramax, offering a significant upgrade over stock coolers. With four times the heat dissipation capacity of factory models, this cooler ensures that your transmission runs cooler and more efficiently, even in the most demanding situations.
Engineered with the densest fins per inch on the market, the Fluidyne cooler delivers exceptional cooling performance. Its fully welded internal splitter plates prevent contamination between hot and cold fluids, maintaining the integrity and effectiveness of your transmission fluid. Constructed from aerospace-grade aluminum with bar and plate technology, this cooler provides maximum heat exchange with minimal pressure drop.
Designed as a direct bolt-in replacement, the Fluidyne cooler uses your existing factory mounts for a straightforward installation. Finished with a proprietary heat-wicking powder coat, it further enhances thermal efficiency.
