I don't agree that if it needs to be flushed it needs to be replaced. If their is something wrong and you think you can flush it to fix it then it's too late, but to just have it serviced is another thing.
I just had my allison trans fluid and filter change at the GMC place. $225 :shock: My trans does not have an internal serviceable filter. It's an external spin on.
