Upgrade your transmission cooling system with this high-efficiency aftermarket 26-row transmission cooler designed as a direct replacement for Ford OE part number 5C3Z-7A095-CA. Built for demanding towing, hauling, street, and performance applications, this upgraded cooler delivers increased cooling capacity to help reduce transmission fluid temperatures and extend transmission life.
Originally used on 2003-2007 Ford 6.0L Powerstroke Super Duty trucks, the 26-row cooler has become one of the most popular transmission cooling upgrades for 1994-1997 OBS 7.3 Powerstroke trucks and 1999-2003 7.3L Super Duty applications due to its significantly improved cooling performance over the smaller factory units.
Whether your factory cooler is leaking, clogged, corroded, or simply undersized for towing and heavy use, this aftermarket replacement offers a cost-effective solution with excellent fitment and performance.
Why Upgrade to the 26-Row Cooler?
Transmission heat is one of the leading causes of transmission failure. Excessive temperatures accelerate clutch wear, fluid breakdown, converter damage, and internal component failure. The larger 26-row design provides substantially more cooling surface area than many stock factory coolers found in earlier 7.3L Powerstroke trucks.
Benefits Include:
- Helps lower transmission operating temperatures
- Ideal for towing and heavy hauling
- Excellent upgrade for performance-built transmissions
- Reduces heat-related transmission wear
- Helps extend clutch and torque converter life
- Large 26-row core design for improved cooling efficiency
- Durable aluminum construction
- Cost-effective alternative to expensive OEM units
- Direct replacement for 6.0L applications
- Popular upgrade for 7.3L Powerstroke trucks
