How Often to Change Allison Transmission Filter

The Allison Transmission filter should be changed every 15,000 miles or 24 months – whichever comes first. It is recommended to change the filter when changing the transmission fluid or if you are having any issues with your transmission. You can purchase an OEM replacement part from a dealership that specializes in Allison Transmissions, or you can use an aftermarket filter which will be cheaper but may not meet all of the quality standards set by the manufacturer.

Before installing a new filter, clean out any dirt and debris from around where it will fit into place and make sure there is no damage to either side of the gasket before installation.

It is recommended that you change the Allison Transmission filter every 30,000 miles. This will help to ensure that your transmission functions as it should and keeps dirt and debris away from the internal components of your vehicle. It’s important to use a quality filter when changing your transmission filter so make sure you purchase one from a trusted source.

If necessary, consult with an expert mechanic or ask for advice at an auto repair shop before making any changes to avoid costly mistakes.

How Often Should a Allison Transmission Be Serviced?

When it comes to servicing Allison Transmissions, the frequency of service depends on a variety of factors such as duty cycles, operating environment and fluid condition. Generally speaking, an Allison Transmission should be serviced every 50-100 hours or 12 months (whichever comes first). It is important to note that during periods of heavy operation (such as hauling) more frequent servicing may be required in order to maintain optimal performance and reliability.

However, it’s important to check with your manufacturer for specific maintenance intervals as this can vary between different models and makes of cars. Additionally, if you live in an area that experiences extreme weather conditions such as very cold winters or hot summers, then you should replace your transmission filter more frequently than the standard interval.

The mechanic can inspect the filter for signs of damage or excessive wear and tear, which could indicate that it needs to be replaced. Additionally, if you notice a strange smell when switching gears or hear unusual noises coming from the engine bay when driving then these could also signify an issue with the transmission filter.
