How many quarts of fluid does an Allison transmission hold?

An Allison transmission typically holds between 12 to 24 quarts of fluid, depending on the specific model and application. The exact fluid capacity can vary, so it's important to consult the owner's manual or manufacturer specifications for the exact fluid capacity of a particular Allison transmission.


Allison Transmission Fluid Capacity Explained


Allison transmissions are known for their durability and reliability in a variety of heavy-duty applications, such as commercial trucks, buses, and off-highway vehicles. The fluid capacity of an Allison transmission is an important consideration, as the transmission fluid plays a crucial role in lubricating and cooling the internal components, ensuring smooth operation and long service life.


The fluid capacity of an Allison transmission can range from as little as 12 quarts for smaller models up to 24 quarts or more for larger, heavy-duty applications. This variation in capacity is due to the different sizes and configurations of Allison transmissions, which are designed to meet the specific needs of different vehicles and applications.


Factors Affecting Allison Transmission Fluid Capacity


Several factors can influence the fluid capacity of an Allison transmission, including:



  • Transmission Model: Different Allison transmission models, such as the 1000, 2000, 3000, and 4000 series, have varying fluid capacities based on their size and complexity.

  • Vehicle Application: Allison transmissions used in commercial trucks, buses, or off-highway equipment may have different fluid capacities compared to those used in lighter-duty applications.

  • Transmission Configuration: Allison transmissions with additional features, such as retarders or power take-off (PTO) units, may require more fluid to accommodate the additional components.

  • Fluid Type: The type of transmission fluid recommended by Allison, such as Allison TES-295 or TES-389 fluid, can also affect the overall fluid capacity.


It's important to always refer to the specific owner's manual or manufacturer recommendations for the correct fluid capacity and type for a given Allison transmission model and application.
