The total capacity of the transmission varies but the average is 19 quarts, I learned a trick that reduces the loss of Transynd when replacing both transmission filters. If you do as many others and remove both filters at once, you lose a significantly greater amount of trans fluid than if you replaced one at a time. Just before summer, I did just that and my total loss of Transynd fluid was just a bit under 1/2 gallon.
