FILTERUP aluminium 8-Pass Transmission Oil Cooler 8-Row, 5/16" Hose Kit with Insta-dapt and Mounting Hardware

FILTERUP Upgrade 8 Pass aluminium transmission oil cooler is a compact, heavy-duty 8-row tube-and-fin cooler kit designed to lower transmission fluid temperatures for improved transmission longevity and consistent shifting under load.

This universal cooler package is built around an 8-pass T-6061 aluminium core and a straight 5/16" hose connection, giving you an affordable way to add extra cooling capacity to cars, trucks, ATVs, and light commercial vehicles. The kit includes hose, clamps, mounting hardware and an Insta-dapt adapter so you can fit it into tight bays or behind bumpers without fabricating brackets. Its corrosion-resistant aluminium construction and flexible CPE hose make it suitable for daily drivers and work vehicles that see towing, hauling, or frequent stop-and-go traffic.

How does this cooler reduce transmission heat during towing or heavy use?

The 8-pass design forces transmission fluid through multiple internal channels so heat transfers rapidly to the fins and then to ambient air. Lowering fluid temperature reduces thermal breakdown and helps maintain consistent hydraulic pressures so shifts remain smooth under stress.

• Eight internal passes increase surface area for faster heat transfer.
• T-6061 aluminium core resists corrosion while shedding heat efficiently.
• Tube-and-fin construction maximizes airflow through the core.
• Included hose and clamps ensure a sealed, oil-tight connection.

Will this fit my vehicle’s transmission lines and where can I mount it?

The FILTERUP kit is intended for systems with 5/16" internal diameter transmission cooler lines — verify your line size before purchase. The kit ships with multiple mounting rods, clips, foam pads and an Insta-dapt adapter so you can mount it to radiator supports, behind the bumper, or in front of the condenser with minimal modification.

• Compatibility: for 5/16" (8mm) ID transmission lines; check factory line size.
• Mounting: hardware included for radiator support, bumper reinforcements, or custom brackets.
• Vibration protection: foam pads isolate the core from metal brackets.
• Adaptability: Insta-dapt adapter helps integrate with existing fittings.

What materials and parts are included, and how do they affect durability?

The core uses aerospace-grade T-6061 aluminium, chosen for strength, light weight and corrosion resistance, while the connecting hose is CPE for abrasion resistance and high flexibility. The kit provides all routine mounting consumables so you don’t need additional parts for a standard installation.

• T-6061 aluminium core for long-term corrosion resistance and efficient heat dissipation.
• CPE hose resists oil, abrasion and temperature cycles for reliable connections.
• Comprehensive hardware: hose, 4 hose clamps, 4 mounting rods, 4 clips, 4 foam pads, Insta-dapt adapter and 6 rod holders.
• Thoughtful packing prevents damage during shipping and simplifies install checks.

How difficult is installation and what tools will I need?

Installation is straightforward for anyone comfortable working under the hood. Basic hand tools are sufficient for most installs, although vehicles with tight spaces may need simple bracket fabrication or removal of surrounding trim.

• Typical tools: pliers, a ratchet set, screwdrivers and a hose cutter or sharp knife.
• Plan: route hoses away from hot exhaust and sharp edges; secure with supplied clips.
• Time: most installs take one to two hours depending on vehicle access.
• Tip: bleed and top off transmission fluid per manufacturer specs after hookup.

Who is this for: FILTERUP’s Upgrade 8-Pass aluminium transmission oil cooler kit is aimed at drivers who tow trailers, carry heavy loads, or want extra transmission protection for high-mileage or performance applications. It’s also a practical DIY upgrade for mechanics and enthusiasts who need a compact, corrosion-resistant cooler with complete mounting hardware for a quick retrofit on cars, SUVs, ATVs, and light trucks.
