Mobil ATF D/M 

Mobil™ ATF D/M

Mobil ATF D/M provides excellent oxidation and friction stability, anti-wear properties, and low-temperature fluidity desired for most automatic transmissions.

Also see the Mobil ATF D/M product data sheet or find a material safety data sheet.

Advantages offered by Mobil ATF D/M over transmission fluids of lower quality are:

FeaturesPotential Benefits
Excellent oxidation stabilityHelps resists chemical deterioration over long service periods.
High viscosity indexHelps retain adequate lubricating body for severe hot-weather service without thickening excessively at low starting temperatures.
Corrosion preventionHelps provide protection against rusting and corrosion, plus special protection for soldered fittings.
Foaming resistanceContains an effective anti-foaming agent.
Elastomer compatibilityIs not harmful to synthetic rubber seal materials.
Good lubricating characteristicsGives quiet operation, smooth shifting, and excellent wear protection.
Controlled friction propertiesTransmission of power is smooth and efficient throughout all normal temperature ranges.

Mobil ATF D/M is recommended by ExxonMobil for use in applications requiring:

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

Mobil ATF D/M also can be used as the lubricating oil in several types of rotary air compressors under certain service conditions. Its low-temperature properties and resistance to oxidation are important factors in meeting the requirements of this service. (Please consult the manufacturer service manual for required specs before use).

Good maintenance practice dictates that automatic transmissions be checked for proper fluid levels at regular intervals, and that the fluid be drained and replaced at intervals recommended by the manufacturer. Some manufacturers recommend more frequent changes of transmission fluid under severe driving conditions.

Note: Mobil ATF D/M is not recommended for other applications, including GM DEXRON VI, Ford MERCON V, MERCON LV, MERCON SP and Type F ATF
