WOOTON Transmission Cooler Kit 8-Pass 5/16" (8mm) Tube-and-Fin — Compact 12x10 Core with Hoses & Hardware

This compact, universal cooler is built to fit vehicles that use 5/16" (8mm) transmission cooler lines and is designed for straightforward installation where airflow is available. The assembly combines an 8-pass tube-and-fin aluminum core with reinforced hoses and mounting hardware so you get a ready-to-fit kit that addresses overheating risks without major modifications.

How does the 8-pass design improve cooling performance?

The 8-pass configuration forces fluid through multiple passages, increasing contact time with the aluminum fins and improving heat transfer to ambient air. Compared with single-pass coolers, this layout extracts more heat per cubic inch while keeping the unit compact enough for tight engine bays.

• Eight discrete fluid passes for greater heat extraction
• Tube-and-fin aluminum core maximizes surface area
• Compact core: 12" x 10" x 0.75" fits constrained locations

Will this kit fit my vehicle and how easy is installation?

This cooler is universal for systems that use 5/16" inner-diameter transmission lines; verify line size and available mounting space before purchasing. The kit includes mounting rods, clips, foam pads, clamps and an Insta-dapt adapter to simplify a bolt-on installation in most vehicles with adequate airflow.

• Compatible with 5/16" (8mm) ID transmission cooler lines
• Full hardware set for mounting and securing the cooler
• Designed for installation in areas free of debris and with steady airflow

What materials and durability features does the kit include?

The cooler core is formed from T-6061 aluminum alloy for light weight and corrosion resistance, while the supplied hose is constructed from high-quality CPE rated to a 145 PSI working pressure. Temperature ratings span -40°F to 176°F, giving resilience across typical operating environments.

• T-6061 aluminum tube-and-fin core for efficient heat dissipation
• CPE hose rated to 145 PSI working pressure
• Temperature range supports cold starts and high-load operation

What comes in the box and what should I expect during use?

The package contains everything needed to mount and plumb the cooler: a 5/16" (8mm) hose, four mounting rods, four mounting clips, four foam pads, four hose clamps, an Insta-dapt adapter, and the transmission oil cooler itself. Once installed in a location with good airflow, expect reduced fluid temperatures under towing, heavy load, or spirited driving conditions, which helps protect transmission components.

• Complete kit: hose, hardware, foam pads, clamps, adapter and cooler
• Core overall size: 15.35" x 10" x 0.75"; core 12" x 10" x 0.75"
• Recommended: install where airflow is unobstructed and free of debris

Who is this for: Drivers who tow, haul, drive in hilly or hot regions, or those seeking a straightforward preventative upgrade to protect transmission health. It's ideal for owners of cars, trucks, or SUVs that use 5/16" transmission lines and need a compact, durable cooler kit with full mounting hardware. If you’re unsure about fitment, measure your transmission line diameter and available mounting space before ordering; contact WOOTON support for any kit-related questions or issues.
