Hot Shot's Secret Green Diamond ULV Automatic Transmission Fluid, 1 Gal — Full‑Synthetic Ultra‑Low Viscosity

Hot Shot's Secret Green Diamond ULV ATF is a full-synthetic, ultra-low viscosity automatic transmission fluid engineered for modern Ford and GM 10‑speed transmissions and compatible European applications.

This advanced ATF is formulated from 100% Group III synthetic base stocks and a targeted additive system, including Hot Shot's proprietary FR3 Nano Technology, to deliver improved efficiency, thermal stability, and cleaner operation in transmissions that require DEXRON ULV or MERCON ULV fluids. It’s intended for technicians, fleet managers, and informed enthusiasts who need a professional-grade fluid that supports extended drain intervals and consistent shift performance in demanding conditions.

Which vehicles and transmissions is Green Diamond ULV ATF designed for?

Green Diamond ULV ATF was created specifically to meet the ultra-low viscosity requirements of modern 10‑speed transmissions used by Ford and GM. It also suits select European automakers that specify ULV fluids; always consult the owner’s manual or service guide to confirm compatibility.

• Forms: DEXRON ULV and MERCON ULV spec compliance for Ford and GM 10‑speed units.
• Common applications: Ford F‑150, Expedition and GM Silverado, Sierra, Tahoe with 10L80/10R80 or other 10‑speed automatics.
• Also appropriate where OEMs call for ultra-low viscosity ATF in European models.

How does this ATF affect fuel efficiency and drivability?

The ultra-low viscosity base oil reduces parasitic drag inside the transmission, which can help improve mechanical efficiency. Paired with friction-modifying additives like FR3, the fluid enhances shift consistency and can contribute to smoother, more responsive gear changes under load.

• ULV formulation lowers internal fluid resistance for better mechanical efficiency.
• FR3 Nano Technology improves shift feel and reduces wear on friction surfaces.
• Cleaner operation helps maintain consistent hydraulic control and shift timing.

What benefits does Green Diamond ULV ATF provide for longevity and maintenance?

Formulated for increased oxidation and thermal stability, this ATF helps resist breakdown and minimize deposit formation. That stability supports longer drain intervals and fewer service-related interruptions when used per OEM guidance and proper service procedures.

• Enhanced oxidation resistance reduces varnish and sludge buildup over time.
• Improved thermal stability maintains performance under elevated temperatures.
• Designed for compatibility with fluid exchange equipment used in professional shops.

How should I use Green Diamond ULV ATF safely and correctly?

Always verify your vehicle’s recommended ATF specification before use—consult the owner’s manual or manufacturer service information. Drain and refill or perform a fluid exchange following OEM instructions; this product is compatible with most ATF service systems used by professionals and experienced DIYers.

• Confirm ULV specification requirement in your vehicle documentation first.
• Use appropriate service equipment for fluid exchanges to avoid contamination.
• Follow manufacturer-recommended service intervals and procedures for best results.

Who is this for: Hot Shot's Secret Green Diamond ULV ATF is aimed at automotive technicians, fleet maintenance managers, and knowledgeable DIYers working on modern Ford and GM 10‑speed transmissions or other vehicles that require ultra-low viscosity ATF. It’s intended for anyone seeking a synthetic, professional‑grade fluid that preserves shift quality, supports longer drain intervals, and integrates with shop-level fluid exchange equipment—provided the ATF specification matches the vehicle requirements.
