BG Quick Clean for Transmissions quickly and effectively removes damaging deposits and cleans the valve body, filter screen and other important automatic transmission components, keeping transmissions operating efficiently. The automatic transmission contains more moving parts than any other system in a vehicle. After 30,000 miles (50,000 km), automatic transmission fluid breaks down. Deposits form on and around all of those moving parts. Slowly and without notice, those actuating parts begin sticking and gum up, causing gears to slip or chatter and making shifting difficult. BG Quick Clean for Transmissions dissolves and removes deposits from the valve body, the filter screen and many other critical transmission components. An important part of the BG Transmission Service, it is used with the BG PXT® Performance Exchange® for Transmissions.
