Mobil ATF™ D/M

Engineered to provide excellent oxidation stability and help prevent corrosion

Mobil ATF D/M automatic transmission fluid provides excellent oxidation and friction stability, anti-wear properties and low-temperature fluidity desired for most automatic transmissions. Mobil ATF D/M is recommended by ExxonMobil for use in applications requiring:

  • GM DEXRON® IIIH transmission fluid
  • Ford MERCON® transmission fluid
  • Allison C-4 transmission fluid


Automatic transmissions should be checked for proper fluid levels at regular intervals, and the fluid should be changed at manufacturer-recommended intervals. However, this may vary due to your vehicle's operating conditions. Some manufacturers recommend more frequent changes of transmission fluid under severe driving conditions, such as heavy traffic, high ambient temperature and trailer pulling.
