Prolong Super Lubricants PSL15000 Transmission Treatment - 8-Ounce Bottle is formulated with AFMT advanced technology. It is engineered to treat the metal surfaces of both standard (manual) and automatic transmissions. As the transmission fluid or gear oil circulates, Prolong Transmission Treatment molecules interact with all of the metal surfaces, chemically bonding to create a protective layer that reduces potentially damaging friction and heat. Prolong Transmission Treatment is particularly effective under extreme pressure conditions, providing significant protection against the most costly automotive repairs. It promotes smoother manual shifts and helps restore responsiveness in automatic transmissions, especially in critical quick-acceleration conditions.
