What I Look for First
When I buy Motorcraft Mercon LV Transmission Fluid, the first thing I check is whether it matches my vehicle’s transmission requirements. I always make sure the owner’s manual or service guide specifically calls for Mercon LV, because using the wrong fluid can affect shifting, performance, and long-term transmission health.
