Your vehicle transmission unit is a complex system of carefully designed manual transmission components. The make and model of your automobile impact the size, shape, and location of the fittings, which are the connecting joints that hold the transmission lines in place. These are durable connectors using either male or female threads.


The attachment style of a fitting determines what type of part to buy, and you cannot mix and match pieces. Without proper connections, you may lose pressure when the engine is running. Whether you are upgrading the lines in your vehicle or replacing worn-out components, use quality constructed materials for safety.
