It's hard to give an exact amount of fluid you'd have to replace when installing the Derale transmission cooler part # D13503. Reason being there's typically some loss from having the transmission line disconnected and that makes it hard to account for the exact amount lost. I'd grab a quart or so and then once the install is complete check the level like the owners manual of the vehicle recommends and add as much as needed.
