It provides excellent protection against wear, corrosion, and oxidation, ensuring a longer lifespan for your transmission.

  • Fuel Efficiency: The synthetic formula of Transynd 668 reduces friction between moving parts, resulting in improved fuel efficiency. This not only saves you money on gas but also helps reduce harmful emissions.
  • Allison Approved: Transynd 668 meets all the stringent requirements set by Allison for their transmissions. It is also approved by major vehicle manufacturers such as Volvo and Mack Trucks.

Where to buy?

You can purchase Transynd 668 Transmission Fluid at any authorized Allison dealer or through online retailers such as Amazon or Walmart. Make sure to buy from a reputable source to ensure that you are getting genuine products.

Pricing

The price of Transynd 668 may vary depending on where you purchase it from. On average, a gallon of this transmission fluid can cost between $50 to $70. While it may seem expensive compared to conventional fluids, remember that it offers extended drain intervals which can save you money in the long run.

How much do I need?

The amount of fluid needed will depend on your vehicle’s specific requirements. You can refer to your owner’s manual or consult with your mechanic to determine how much transmission fluid your vehicle needs.

Tips when using Transynd 668

To ensure optimal performance and longevity of your transmission when using Transynd 668, here are some tips to keep in mind:

  • Fully drain old fluid: Before adding new fluid, make sure to fully drain out the old one first. This ensures that there is no mixing of different types of fluids which could affect performance.
  • Avoid overfilling: Overfilling your transmission with too much fluid can cause pressure build-up which could lead to leaks or damage.
  • Frequent checks: Regularly check the color and level of your transmission fluid. If it appears darker than usual or has a burnt smell, it might be time for a change.

In conclusion,

If you own a heavy-duty vehicle with an Allison transmission or even if you have a medium-duty or light-duty vehicle that requires high-quality ATF, then consider investing in Transynd 668 Transmission Fluid. Its unmatched quality and extended service life make it worth every penny spent. With proper maintenance and regular use of this fluid, you can expect improved performance and longevity of your vehicle’s transmission system.
