FILTERUP 8-Pass Aluminum Transmission Oil Cooler — 8-Row Tube & Fin, 5/16" Hose Kit, T-6061 Durable Cooling

FILTERUP 8 Pass aluminium transmission oil cooler is a universal 8-row tube-and-fin kit that lowers transmission fluid temperature and extends component life for vehicles using 5/16" ID cooler lines.

Keeping transmission fluid within a safe operating range helps reduce wear, prevent overheating, and maintain shifting performance. This FILTERUP cooler is built from T-6061 aluminum with an 8-pass, 8-row tube-and-fin design and ships with a 5/16" (8mm) hose, mounting hardware, clamps and an Insta-dapt adapter for a straightforward installation on many vehicles. The kit targets frequent towing, heavy loads, or high-temperature operating conditions where extra cooling is beneficial.

How does this cooler reduce transmission temperatures?

The 8-pass layout forces fluid through multiple channels so heat transfers efficiently from the oil to the aluminum fins. Greater surface area and steady airflow over the fins dissipate heat faster than a single-pass or smaller core cooler.

• Eight passes increase fluid contact time and heat exchange.
• Tube-and-fin core enlarges cooling surface area for faster heat rejection.
• T-6061 aluminum construction improves thermal conductivity and resists corrosion.

Will it fit my vehicle and how simple is the installation?

This kit is designed for universal compatibility with most applications that use 5/16" (8mm) ID transmission cooler lines; always verify your line size before purchase. The package includes a pre-cut 5/16" hose, four mounting rods and clips, foam pads, hose clamps and an Insta-dapt adapter to streamline mounting and connection.

• Check line inner diameter—must be 5/16" (8mm) for a direct fit.
• Included mounting hardware fits common radiator or frame mounting points.
• Basic hand tools are sufficient for most installations; professional help recommended for complex routing.

What materials and parts are included, and why do they matter?

The cooler and fittings use T-6061 aluminum that resists corrosion and conducts heat efficiently, while the supplied hose is CPE for abrasion resistance and flexibility. The full hardware kit helps prevent leaks and secures the cooler to minimize vibration and wear.

• T-6061 aluminum core provides durability and good thermal transfer.
• CPE hose offers flexibility and abrasion-resistant performance.
• Mounting rods, clips, foam pads and clamps ensure secure installation and reduce vibration.

Who is this for? If you tow trailers, haul heavy loads, drive in hot climates, or want extra protection for an older transmission, this FILTERUP 8-pass cooler adds a robust cooling step between your transmission and radiator. It’s aimed at DIY installers and mechanics seeking an affordable, universal upgrade to reduce transmission fluid temperatures and improve long-term reliability. Always confirm hose size compatibility and consider professional installation for complex vehicle systems or limited access areas.
