Motorcraft MERCON LV Automatic Transmission Fluid — 12-Quart Case, Ford‑Approved Low‑Viscosity ATF

Motorcraft MERCON LV Automatic Transmission Fluid is a Ford-approved, low-viscosity ATF engineered to deliver reliable shifting, protection, and temperature performance for compatible Ford and Lincoln automatic transmissions.

Designed and recommended by Ford Motor Company, this Motorcraft MERCON LV Automatic Transmission Fluid in a 12-quart case supplies the specific fluid properties modern electronically controlled transmissions require. It combines hydroprocessed base oils with purpose-built additives to balance low-temperature flow, high-temperature stability, and friction control—helping maintain smooth gear changes and resist degradation over time. The product is dyed red for easier leak spotting and is not suitable where MERCON V, MERCON SP, Continuously Variable Chain Type fluids, or certain other specified fluids are required.

How does MERCON LV improve shifting in modern transmissions?

MERCON LV is formulated to provide consistent friction characteristics across temperature ranges, which helps transmissions achieve crisp, predictable shifts. Its additive package reduces the chance of shudder while supporting hydraulic control at both cold starts and high operating temperatures.

• Low-viscosity base oils promote quick pump-up and smooth engagement at low ambient temperatures.
• Additives preserve clutch friction stability to avoid slip or harsh engagement.
• Thermal and shear stability maintain performance under heavy loads and heat.

Will this fluid protect my transmission from wear and deposits?

Yes — the formulation contains anti-wear and dispersant additives that minimize metal-to-metal contact and inhibit the formation of gum, sludge and lacquer. That helps keep valve bodies, clutches and torque converters cleaner and functioning within design tolerances.

• Anti-wear agents reduce component wear during high-load conditions.
• Detergent and dispersant chemistry helps prevent deposits and sticking valves.
• Corrosion inhibitors reduce rust risk inside the transmission housing.

Is MERCON LV suitable for extreme temperatures and long drives?

The fluid shows both good low-temperature flow for cold startups and robust oxidation resistance for sustained high-temperature operation. Those properties reduce the chances of accelerated breakdown during towing, heavy-duty use, or prolonged highway driving.

• Low-temperature fluidity ensures fast lubrication on cold mornings and minimizes harsh shifts.
• Oxidation and shear stability resist viscosity loss during extended high-heat operation.
• Foam inhibitors preserve hydraulic consistency under repeated load cycles.

Are there any important restrictions or compatibility notes?

Use only where MERCON LV is specified by the vehicle manufacturer; this product is not approved for applications calling for MERCON V, MERCON SP, Continuously Variable Chain Type fluids, Motorcraft Premium ATF, FNR5, or Type F fluids. It is also not intended for transfer cases.

• Confirm your vehicle’s owner manual or dealer guidance before use.
• Do not substitute in transmissions requiring a different MERCON specification.
• Available as a 12-quart case for service shops or multi-fluid maintenance needs.

Who is this for: Motorcraft MERCON LV ATF in a 12-quart case is ideal for Ford and Lincoln owners, independent mechanics, and fleet managers who need the factory-recommended low-viscosity fluid for compatible automatic transmissions. Choose this product when the vehicle specification lists MERCON LV to ensure correct friction performance, reliable shifting, and long-term transmission cleanliness and protection.
