[30-70PSI][30-70PSI,Black]
EVIL ENERGY Fuel Pressure Regulator 6AN EFI Bypass Return Adjustable 20-140psi Black&Red - Red

Durable Construction: Precision-machined 6061-T6 aluminum alloy, corrosion-resistant and heat-tolerant (withstands harsh engine bay conditions), ensuring long-term reliability.

EFI System Compatibility: Fits most vehicles' electronic fuel injection (EFI) systems; maintains stable fuel pressure for optimized combustion, performance, and fuel economy.

Fuel Compatibility: Works with gasoline, E85, and alcohol/ethanol; not compatible with diesel fuel; note: nylon braided fuel lines are not E85-compatible (use PTFE-lined hoses for E85).

FAQs about Transmission Oil Coolers

What type of transmission cooler works best?

The best type of transmission cooler depends on your vehicle and driving conditions. For most vehicles, a universal transmission cooler provides reliable cooling for everyday use. For high-performance or heavy-duty applications, a larger automatic transmission oil cooler with fan assistance can offer superior heat dissipation and protection.

The cost of a transmission cooler varies based on type and features. A basic universal cooler kit can start around $50–$100, while complete systems with mounting brackets and fan kits can range from $150 to $400. Investing in a quality cooler helps protect your automatic transmission and can save costly repairs down the line.

Driving with a leaking automatic transmission oil cooler is not recommended. Even a small leak can lead to low transmission fluid levels, overheating, and eventual transmission damage. It’s best to repair or replace the cooler immediately to prevent further issues.

A failing transmission cooler can cause your transmission fluid to overheat, which may result in slipping gears, delayed shifting, or complete transmission failure. Regular inspection and proper maintenance of your cooler can prevent costly repairs.

Fixing a transmission leak can range from $100 to over $1,000 depending on the source and severity of the leak. Replacing a universal transmission cooler is often a cost-effective solution compared to repairing internal transmission damage caused by overheating.
