Allison 3000/4000 Series Allison Transmission Fluid change is now available at our RTS Learning Center page. Changing the transmission fluid in 3000/4000 Series Allison Transmissions is a critical maintenance task that ensures the longevity and efficiency of the transmission. Over time, transmission fluid can break down, become contaminated with metal particles, and lose its effectiveness in lubricating and cooling the internal components.

During the fluid change, technicians drain the old fluid, replace the filter, and refill with fresh, high-quality fluid. This process not only removes contaminants but also helps in cooling the transmission by maintaining proper fluid levels and pressure. 

By adhering to the manufacturer’s guidelines, fleets can avoid costly repairs and ensure the transmission operates efficiently for years to come.
