You may get tired of hearing this, but there are three good sources for knowing your Allison transmission fluid capacity. These sources are the same for other fluids as well. The first is to check your owner’s manual to see what the manufacturer says.

They built the transmission and they will have the best answer for you. They will also recommend a good transmission fluid brand for you to use. The next best source will be your dealer. They should have the specs for all the models they sell and tell you about different top fluid brands you should use.

The final source will be a top mechanic that you trust. They work on these transmissions and know exactly what they need. If they are honest, and not all mechanics are, then you should get the capacity plus information on good transmission fluid brands even if they are not famous.
