Mobiltrans™ HD 10W

Extra-high-performance transmission and drivetrain oil

Mobiltrans HD 10W is an extra-high-performance, heavy-duty transmission and drivetrain oil engineered to meet or exceed the requirements of the rigorous Caterpillar TO-4 specification. This product is uniquely designed to optimize the performance of powershift transmissions, gearboxes and final drives. In hydraulic applications, it provides maximum protection – even in high-pressure systems.

This technology combines selected base oils and an advanced additive system to deliver the precise performance parameters needed to maximize the productivity of construction, quarrying and mining equipment operating in severe conditions. This product offers a clear performance advantage over the use of mixed fleet engine oils and previously used lubricants meeting Caterpillar TO-2.

Mobiltrans HD 10W transmission and drivetrain oil is recommended by ExxonMobil for use in:

  • Heavy-duty transmissions, gear boxes, final drives and hydraulic systems used in off-highway applications
  • Off-highway industries, including construction, mining, quarrying and agriculture
  • Manual, powershift and automatic transmissions where Allison C-4 fluids (SAE 10W and 30 grades) are called for, including Twin Disc and transmissions calling for Type F fluids
  • Most mobile equipment hydraulic applications

Mobiltrans HD 10W transmission and drivetrain oil delivers exceptional performance in today’s powertrain transmissions, drivetrains and hydraulic systems.


Features and benefits

  • Compatible with modern clutch materials and elastomers, which can help deliver longer clutch life
  • Increased levels of anti-wear and load-carrying capability can result in reduced gear wear and extended life in transmissions, gearboxes and final drives
  • Excellent foam control protection delivers top performance in wet brakes and controls brake chatter
  • Excellent thermal and oxidation stability provides outstanding hydraulic oil stability and protection against high-pressure pump wear
  • Lower viscosities offer very good low-temperature pumpability, which supports reduced time from startup to production
