Rein TRC0520 Automatic Transmission Oil Cooler Tube - Front

Rein TRC0520 Transmission Oil Cooler Tube

Rein TRC0520 is an OE-quality automatic transmission oil cooler tube built for direct replacement on select Toyota and Lexus applications. It uses premium hose material engineered for transmission cooling service, with resistance to heat, oil, and ozone that can degrade standard rubber lines over time.

Compatible with 2003-2009 Toyota 4Runner, front; 2007-2009 Toyota FJ Cruiser, front; 2003 Lexus GX470, front; and 2004 Toyota 4Runner, front to 10/03, this transmission oil cooler tube supports proper fluid routing in the cooling circuit.

Key Features

• OE-quality hose construction for direct-fit replacement
• Built to handle the pressure demands of transmission cooling systems
• Resists heat, oil, and ozone exposure that can shorten hose life
• Restores transmission fluid flow through the cooler circuit
• Rein TRC0520 application-specific fitment for select Toyota and Lexus models

Detailed Description

The Rein TRC0520 automatic transmission oil cooler tube is designed as a replacement for the factory cooler line on supported vehicles. Its hose material combines NBR, CR, rubber, and steel elements for durability in a high-pressure, high-temperature environment. This makes it a practical choice when servicing a leaking, cracked, or deteriorated transmission cooler tube on a Toyota 4Runner, Toyota FJ Cruiser, or Lexus GX470. This part cross-references Monroe Shocks & Struts (e.g., 3290760070) for the same application.

Common Problems This Part Can Address

• Transmission fluid leaks from a worn cooler tube
• Cracking or hardening caused by heat and ozone exposure
• Restricted fluid transfer through a damaged line
• Loss of proper transmission cooling performance
• Fitment issues from using a non-OE-style replacement line

Installation Notes and Tips

Verify vehicle year, model, and front-position fitment before installation. This part is application-specific, so match the original routing and connection points on the vehicle. Inspect related seals and mounting points during service, and confirm the cooler circuit is clean before returning the vehicle to operation. Rein TRC0520 is listed for 2003-2009 Toyota 4Runner, 2007-2009 Toyota FJ Cruiser, and 2003-2004 Lexus GX470 front applications.

Quality Assurance

Rein manufactures this transmission oil cooling hose to OE-quality standards using materials selected for transmission cooling service. The design focuses on durability under pressure and resistance to common causes of hose failure in automatic transmission systems.
