How does the integrated transmission oil cooler benefit my car?

Including a transmission oil cooler in the radiator assembly helps regulate automatic transmission fluid temperature, which supports consistent shifting and reduces thermal stress on transmission components. Combining both coolers into a single assembly simplifies installation and reduces the number of separate components under the hood.

• Maintains transmission fluid temperature within optimal range for smoother shifts
• Reduces the need for a separate aftermarket cooler and extra plumbing
• Single, welded assembly improves durability and reduces leak points

Knowing core dimensions and inlet/outlet sizes ensures proper fit and hose compatibility. This A-Premium unit lists clear measurements so you can compare to your original radiator before ordering.

• Core height: 13-3/8 inches
• Core width: 27-1/16 inches
