  • Material: Synthetic

We’ll begin with the top of our list, Spectro Oil R.HDGP6 transmission lubricant. It is the best solution for Harley enthusiasts who are fed up with their loud 6-speed automatic transmission. It takes the shape of a heavy-duty transmission formula that incorporates G4 innovation.

Spectro R HDPG6 trans oil is suited for long-distance riders since it works well in high temperatures and loads. As it circulates and gathers dirt and debris, the oil helps clean your engine. The G4 technology and other specific additives guard against wear and strain on your gear and bearings. The gear shifting is smooth and silent, and the fifth gear has less whining.

Pros

G4 Innovation: G4 technology and additional additives are included in Spectro R HDPG6 trans oil. As a result, it protects against gear and bearing wear and strain. The oil also improves the film strength between gear teeth, reducing drag over the gear. As a result, you will not only have a quieter transmission, but you will also ensure that your gear lasts a long time.

Smooth-shifting: As previously said, the 6-speed transmission performs admirably in terms of power and efficiency. However, it can be a little noisy. Experienced riders may also detect an unpleasant whine in 5th gear. The usage of Spectro R HDPG6 tranny oil greatly decreases noise and 5th gear whine.

All-weather performance: When it’s chilly, some motorcycles have trouble shifting gears. Others will have difficulty communicating at severe temperatures. Your bike will function in any condition when you use Spectro synthetic oil. If you ride long distances, the Spectro R HDPG6 comes in handy since it functions well even when the engine heats up and even while carrying large loads.

Cons

It’s a little difficult to collect in stores, and it’s also a little pricey, but it’s worth it.

Amsoil MYTQT-EA Synthetic V-Twin Trans Fluid, 1 quart, is specially formulated to resist the rigors of engine, transmission, and primary chaincase usage. Smooth, silent shifting with long component life is to be expected. It has wear-prevention compounds, and the 100 percent synthetic-based oil will not split (thin out). As a result, it does not expose the transmission or fundamental components to increased wear.

This synthetic oil performs well in all weather conditions. When you use it, it does not violate the guarantee on your Harley-Davidson motorcycle. When you use the Amsoil MYTQT-EA synthetic oil, you will never miss a shift since it ensures optimal acceleration. It helps you save money and time on upkeep.

Pros 

Allows for smooth transitions: No driver wants to miss a shift when out on the road. You also want the best acceleration possible at all speeds. As a result, Amsoil MYTQT-EA Synthetic V-Twin Trans Fluid, 1 qt is ideal for you. The oil has viscometric and frictional qualities that make it simple to move from one gear to the next for best performance.

Additionally, the fluids preserve your gear and bearings from wear and tear, decreasing gear noise and eliminating loud thumps. As a result, you can be confident that your Harley Davidson Sportster, Softail, or other models will respond to your commands and provide you with an unforgettable ride.

Hardly oil changes: You want a tranny that not only performs well but also saves you money on upkeep. You don’t want a fluid that will force you to go to the garage every few weeks to change the oil.

As previously stated, Amsoil MYTQT-EA trans fluid can endure tremendous pressures between gear teeth, and it also operates well at high temperatures without losing viscosity. As a result, you will have fewer trips to the garage to change the oil, saving you money and giving you more time to do other things.

Performs well in high temperatures: With the Amsoil MYTQT-EA motor oil, you can be confident that your vehicle will not let you down in any condition. It can function efficiently in hot temperatures and will still provide you with optimum efficiency when the temperatures drop outside.

Cons

It is not multipurpose: Because the Amsoil MYTQT-EA fluid is not multipurpose, you will pay additional costs. You’ll need separate motor oil for your engine, clutch, and chain, as well as synthetic oil for the transmission.

3. Red Line 42804 V-Twin Transmission Oil

Red Line 42804 V-Twin Transmission Oil

Specifications

  • Brand: Red Line
  • Weight: ‎4.22 pounds
  • Twin Cam engines

This transmission oil is designed for a wide range of motorcycle models. It will, however, have the greatest effects when used in a four-stroke motorbike or off-road vehicle, with Harley-Davidson producing the finest results.

This oil is great for racing since it changes swiftly and smoothly. Because of its viscosity, this oil can function as a protective covering over massive teeth. This system ensures that the oil is thick enough. Even if the oil hasn’t been changed in a long time, it still provides dependable service. The use of this oil has the advantage of preventing overheating.

Pros

It reduces gearbox noise: For every rider, nothing disturbs them more than a gearbox that sounds like it is going to fall off in the next minute. Red Line 42804 V-Twin trans oil comes with friction modifiers that help to reduce gearbox noise significantly. The oil helps to eliminate the noise that comes from shifting gears. The tranny oil is known as “shockproof” because it substantially reduces the noise. The fact that it offers thick oil films between the gear teeth reduces friction and eliminates noise during the shifting of gears.

Gears shift smoothly: Shifting gears on a sports bike is critical because it impacts acceleration, which can make the difference between winning and losing. As a result, the Red Line 42804 V-Twin oil comes in handy since it makes gear shifting a breeze.

High viscosity: Red Line 42804 V-Twin oil has viscosity properties that give a strong thickness that offers a layer of security over the gear teeth. As a result, by minimizing friction while shifting, it substantially preserves the teeth from wear and strain.

Super efficient: Efficiency is when you can drive for longer distances without changing the oil. Red Line Big Twin transmission synthetic oil not only allows you to run for a longer period of time between oil changes, but it also preserves your engine throughout that time. The fact that the oil circulates in the vehicle also helps to maintain it clean. It catches all the trash and dirt that might clog up and cause harm to your motor as it circulates.

Lower temperatures: High engine temperatures can cause overheating, reducing not just the performance but also the life of your vehicle. A sports bike is especially vulnerable to overheating. Red Line V-Twin synthetic oil works to lower temperatures, minimizing overheating and enhancing performance.

Cons

Sensitive riders may detect a burning oil scent, which can be annoying.

Conclusion

You must select the best transmission oil for your Harley-Davidson based on your budget and availability. Whichever trans oil you eventually decide to use on your bike, make sure you change the oil on a regular basis.

The initial oil change is usually recommended after 500 miles, with subsequent oil changes every 2500 miles. It is even recommended that the oil filter be replaced at the same time as the oil.

No matter what oil you use or how excellent the oil is, if it is not changed on a regular basis, it will not operate to reduce heat, wear, and strain in the gearbox. Once again, it is always a good idea to consult your handbook to confirm that the oil you purchase is appropriate for your vehicle.
