Transmission catch cans, also known as transmission breathers or vent cans, are additional components that can be installed in a car's transmission system. They are designed to capture & separate oil vapors or excess pressure that may accumulate within the transmission, preventing them from being released into the environment or recirculated back into the transmission. Catch cans typically consist of a small canister with an inlet & outlet, & they are often equipped with internal baffles or filters to trap oil particles & contaminants. The catch can is connected to the transmission breather or vent line, allowing it to capture any oil mist or vapors that may escape from the transmission. By collecting these substances, catch cans help to reduce the risk of oil contamination, prevent the buildup of sludge or deposits, & maintain optimal transmission performance. Regular maintenance & inspection of the catch can are necessary to ensure proper functioning & to empty or clean out the accumulated oil. It's worth noting that catch cans are not standard equipment in most vehicles & are often aftermarket additions, particularly for performance-oriented or modified cars. Installing a catch can can be beneficial in high-performance applications or situations where the transmission is subject to higher stress levels, as it helps maintain a cleaner & more efficient transmission system.
