Derale Performance Automatic Transmission Oil Cooler Coolant Line Connector

Derale Performance Transmission Oil Cooler Coolant Line Connectors

When building or upgrading an automatic transmission cooling system, the fittings and connectors that tie everything together are every bit as important as the cooler itself. Derale Performance has long been recognized as one of the most trusted names in automotive thermal management, and their automatic transmission oil cooler coolant line connectors reflect the same engineering discipline that defines the rest of their product lineup.

Why Connectors Matter in Transmission Cooling

High heat is the number one killer of automatic transmissions. High temperatures are the leading cause of automatic transmission failure, making it critical to ensure the transmission doesn't overheat while towing, off-roading, or sitting in heavy traffic on a hot day. A transmission oil cooler is only as effective as the connections that route ATF through it — a weak or improperly sized fitting can create flow restrictions, leaks, or pressure failures that undermine the entire cooling circuit.

Derale's Approach to Cooler Line Connections

Derale's coolant line connectors are purpose-engineered to integrate seamlessly with their broader transmission cooling ecosystem. Their product lineup includes dedicated transmission cooler fittings alongside engine oil cooler installation kits and direct-fit cooling kits , meaning the connectors are designed to work in concert with Derale's full range of coolers — not as afterthoughts. This ecosystem approach ensures compatibility whether you're connecting to a factory radiator port or routing lines to a remote-mount auxiliary cooler.

Derale Performance is a well-known manufacturer of cooling products for everything from engine oil to automatic transmissions , and that breadth of experience informs the precision of their fittings. Derale-supplied coolant components are already cut precisely to length and finished with anodized AN fittings — the standard for high-quality builds that won't leak. This commitment to AN-style fitting standards means DIY installers and professional shops alike can count on secure, repeatable connections.

Application Coverage and Fit

Derale's line connector products span a wide range of domestic and import applications, covering different port sizes and thread configurations found across popular transmission families. Whether you're working on a Dodge 518/618/727 platform, a GM automatic, or a Jeep-spec unit, Derale engineers their fittings to address the real-world port configurations encountered in the field. Select Derale fittings — such as the 14010 — are specifically designed to work with deep transmission cooling pan applications, functioning as filter extenders that ensure proper oil pickup geometry is maintained when a deep pan replaces a stock unit.

Derale puts serious time and effort into installation documentation — instructions that are complete, extremely well illustrated, and leave nothing for the installer to figure out on their own. This dedication to usability makes their connector hardware approachable for enthusiasts tackling a cooling system build for the first time.

The Right Connector for a Complete Cooling System

Derale's transmission oil cooler coolant line connectors are a natural complement to their stacked-plate and tube-and-fin cooler families. Their transmission cooling product range spans everything from single-pass and dual-pass heat sink coolers to their Hyper-Cool, Hyper-Cool Extreme, Electra-Cool, and Atomic-Cool remote-mount cooler series , and the right line connectors ensure each of those systems performs as designed. Sourcing connectors from the same manufacturer as your cooler eliminates guesswork around thread pitch, port size, and flow capacity — and keeps your transmission running at its best.
