When choosing the best transmission fluid for a Harley 6 speed, it is important to choose one that is 75W90 Gl-1 in spec. This oil will reduce friction and drag, and extend gear life. The highest quality fluids will last longer than the average product, and will improve the performance of your motorcycle. It will also improve the sound and performance of your bike. Here are a few choices for transmission fluid.
o Delvac Synthetic Transmission Oil: This is a specially formulated oil that is designed for use in motorcycles and other vehicles. This type of fluid has high viscosity index and controlled friction properties. It will prevent gear component overheating, and it will also prevent foaming. This type of transmission fluid can be installed in almost any vehicle. It is a great choice for Harley Davidson enthusiasts because it is designed specifically for use in 6-speed machines.
o Lifeguard Trans Fluid: When you replace your transmission fluid, you should choose one that is made for motorcycles. The Lifeguard Transmission Fluid provides consistent performance no matter what the weather is. This type of transmission oil is a bit complicated to change, though. It requires two consecutive flushes at specific temperatures. The best way to find a quality product for your Harley 6 speed is to read the manufacturer’s instructions.
