Prolong transmission treatment was formulated to protect and repair manual and automatic transmission systems. Friction and heat can be extremely damaging in the long run and this formula was designed to reduce this damage by chemically bonding with the system’s metal components and forming a much-needed protective layer. This product comes in an 8-ounce bottle and is extremely beneficial when the system is under immense pressure. It also helps with rough manual shifting and is capable of fixing responsiveness issues in automatic transmissions. Prolong is compatible with commonly used transmission fluids and gear oils and does not affect clutches or bands.
