Hot Shot's Secret Green Diamond ULV ATF 1 Gallon — Full-Synthetic ULV for Ford & GM 10-Speed

Built from 100% Group III synthetic base oils and Hot Shot's Secret FR3 Nano Technology, Green Diamond ULV ATF delivers an advanced additive package that keeps fluid cleaner longer while improving efficiency and shift quality. It was formulated to meet ultra-low viscosity OEM requirements such as DEXRON ULV and MERCON ULV, giving professional shops and experienced DIYers a transmission fluid designed for today’s high-performance 10-speed gearboxes.

How does this ATF improve transmission efficiency and performance?

Green Diamond ULV reduces parasitic loss thanks to its ultra-low viscosity base, which helps lower internal drag and can improve fuel economy and horsepower delivery. The proprietary FR3 friction modifier smooths shift transitions and promotes consistent engagement across operating temperatures.

• Ultra-low viscosity reduces mechanical drag for better efficiency.
• FR3 Nano Technology improves shift feel and reduces wear.
• Advanced additives resist oxidation to maintain performance over time.

Which vehicles and transmissions are compatible with Green Diamond ULV ATF?

This fluid is targeted at Ford and GM models that require ULV-spec ATF, including many vehicles equipped with 10-speed transmissions such as 10L80 and 10R80 families. It is also suitable for select European cars that specify an ultra-low viscosity fluid—always verify compatibility in the vehicle owner’s manual before use.

• Formulated to meet DEXRON ULV and MERCON ULV specifications.
• Compatible with Ford F-150, Expedition and similar 10-speed applications when ULV is required.
• Works in GM trucks like Silverado and Tahoe equipped with 10-speed units when specified.

What maintenance and service considerations should I know?

Use Green Diamond ULV ATF according to the manufacturer’s service interval recommendations and drain/refill procedures. It’s compatible with most OEM fluid exchange systems, but confirm ULV compatibility and follow safe fluid-handling practices during service.

• Check the owner's manual to confirm ULV ATF approval for your transmission.
• Drain and refill per manufacturer guidelines; suitable for professional fluid-exchange equipment.
• Provides longer drain intervals through higher thermal and oxidation stability compared with conventional fluids.

Who is this for? Green Diamond ULV ATF is aimed at fleet technicians, professional transmission shops, and knowledgeable DIYers who service modern 10-speed Ford and GM transmissions or European vehicles that call for ultra-low viscosity ATF. If you need a professional-grade, synthetic ULV fluid that balances cleaner operation, improved shift quality, and compatibility with OEM exchange systems, this 1-gallon container is sized for both individual service jobs and small-fleet maintenance.
