Hot Shot's Secret Green Diamond ULV ATF 1 Gallon — Full-Synthetic Group III, FR3 Nano Tech for Ford & GM 10-Speed

Built with advanced FR3 Nano Technology and a high-performance additive package, this Green Diamond ULV ATF delivers improved thermal stability, deposit control, and lubricity in a formula intended to keep modern ultra-low viscosity transmissions cleaner and operating more efficiently. It’s formulated to meet OEM ULV specifications for Ford and GM 10-speed units (including applications using 10L80, 10R80 and similar designs) and is suitable for professional shops and experienced DIYers who follow manufacturer guidelines for fluid exchange.

How does Green Diamond ULV ATF affect shift quality and drivetrain efficiency?

The FR3 friction modifier and carefully balanced additives enhance lubricity and promote smoother, more consistent shifts while reducing parasitic drag. That combination can improve throttle response and make gear transitions feel firmer and more controlled without changing transmission hardware.

• FR3 Nano Technology for improved friction characteristics and smoother shifts
• Ultra-low viscosity base oils to reduce parasitic loss and help efficiency
• Stable additive package to maintain consistent shift feel over time

Will this ATF protect my transmission under heavy use or long intervals?

Formulated to resist oxidation and thermal breakdown, Green Diamond ULV ATF is designed to limit deposit and sludge formation, which helps maintain cleanliness and component longevity. The product’s wear-resistant additives support durability during towing, hauling, or frequent stop-and-go driving when used per OEM service intervals.

• Improved oxidation and thermal stability for extended fluid life
• Deposit and sludge prevention to keep clutch packs and valves free-moving
• Higher wear resistance compared with conventional fluids

Is Green Diamond ULV ATF compatible with my vehicle and service equipment?

This fluid is engineered to meet DEXRON ULV and MERCON ULV specifications and is intended for Ford and GM 10-speed transmissions and select European models requiring ultra-low viscosity fluids.
