The GT-R requires the transmission to be over filled for high G forces, this helps to prevent the transmission filter from sucking air in and causing miss shifts. Once the transmission has been overfilled (2 quarts recommended) it then has a tendency to push the fluid out of the top vent on the transmission. The Buschur Racing Remote Fill Catch Can allows you to add the two quarts to the transmission without the use of a remote pump. The can then allows the transmission to push the extra fluid up into the can and drain back so the fluid levels are maintained at all times. The kit comes complete with the can, filter, mounting hardware and hoses.
