An automotive transmission cooler engineered to reduce excessive heat buildup and improve cooling efficiency. Owners of hot rods and classic engines gain reassurance when transmission temperatures remain under control during demanding use. Is Hihaha Transmission Oil Cooler the right fit for a specific engine bay and make?
⚡ At a Glance
- • Cooling Efficiency: Dual-pass finned design increases fluid contact time with cooling surfaces for improved heat transfer
- • Best for: Owners of hot rods, classic engines and vehicles needing extra transmission cooling
- • Not ideal for: Applications requiring OEM-specific fittings or where a 12-inch cooler cannot be mounted
Dual-pass flow forces fluid through the core twice to boost heat dissipation. Polished aluminium construction with clean welds targets durability while keeping weight low.
Lower operating temperatures - thanks to dual-pass finned design
Dual-pass layout channels transmission fluid through the tube twice, increasing exposure to the finned surface so more heat transfers to ambient air. Fins expand surface area and improve convective cooling even at modest airflow.
Reduced operating temperatures help slow fluid degradation and support smoother gearbox performance under sustained use.
Long-lasting build quality - with polished aluminium alloy and clean welds
Polished aluminium alloy provides wear resistance and high strength while remaining lightweight; neat welds contribute to structural integrity and leak resistance. Aluminium also resists many common forms of corrosion compared with untreated steels.
Durable construction suits repeated fitment and long-term service, reducing the need for early replacement.
Compact fitment across many cars - with 1/4" NPT and compact dimensions
Overall length is 31 cm (12 inches), extending to 36 cm (14 inches) with brackets; fittings use 1/4" NPT and the core diameter is 7.5 cm (3 inches), with 3.6 cm centre-to-centre spacing. These dimensions align with common aftermarket mounting patterns.
Compact footprint and standard thread size simplify installation in tight engine bays and are compatible with a wide range of classic and aftermarket setups.
✨ The 4 Key Reasons for Hihaha Transmission Oil Cooler
- Dual-pass flow - Cuts fluid temperature peaks during sustained heavy loads
- Finned tube surface - Speeds heat transfer compared with smooth-core coolers in traffic
- Polished aluminium alloy - Offers corrosion resistance while keeping weight low for easier installation
- Compact 12in footprint - Fits tight engine bays and mounts with included brackets
