About TRANSYND
Allison Transmission and Castrol Industrial North America have teamed up to launch a new synthetic automatic transmission fluid designed for heavy-duty automatic transmissions. TRANSYND is a new product that has been certified for use in all current vehicle models with all current truck and bus applications.
Customers now have a third option for transmission fluid, which may be used in place of DEXRON III or Alligin C4. Customers may select from a variety of DEXRON-III or Allison C4 high-quality fluids, or they can switch to TRANSYND and extend drain intervals. Extended drain intervals have been demonstrated to be cost-effective by reducing maintenance costs while also delivering superior performance with TRANSYND. Onboard data analysis techniques, as well as transportation models and simulations, are used to figure out how best to optimize the advantages in severe vocations like bus or subway fleets with more cars and fluid change intervals that are more frequent. Similar cost savings may also be realized in broad (lighter) duty occupations like school buses, motor homes, and so on. Life Cycle Cost analysis software has been created to assess potential savings based on a customer’s specific operation conditions and maintenance practices.
At the most severe operating conditions, TRANSYND has performed significantly better than competing fluids. Extensive drain intervals have been proved through fleet testing in severe duty situations. This paper examines the rationale behind the creation of TRANSYND and summarizes the findings of several bench, transmission, and fleet validation tests. The advantages of utilizing this innovative product in Allison transmissions are also discussed.

Castrol TranSynd
TES 295 and TES 468 approval TranSynd is a high-quality, synthetic powershift and automatic transmission fluid with TES 295 and TES 468 certification. It’s designed for use in all types of vehicles requiring Dexron III / Mercon® ATF, including buses and garbage trucks with automated transmissions.
The high thermal and oxidative stability of synthetic oils allows for excellent viscosity consistency throughout the transmission, which prevents deposits and oil thickening – this extends gear life and avoids incorrect gear changes.
Under all situations, TranSynd has excellent transmission cleanliness and allows for longer oil drain and fewer visits.
The reduced friction levels eliminate friction, resulting in greater oil and component life as well as faster drain and servicing. Fuel cost savings and lower emissions are possible because of decreased engine power input.
The free movement of the gears is further assured by optimized frictional characteristics that eliminate friction at all ambient temperatures and loads.
Constant frictional properties make driving more pleasant.
It’s also worth noting that the oil pump has a built-in valve that prevents ice and water from entering into the system. This oil pump is made up of two stainless steel balls that fit together like puzzle pieces.
Gear changes are more fluid and pleasant. When changing gear, the motor unit is moved closer to the rear wheel for better response and comfort.
The higher the shear stability, the better. It is important to maintain full oil drain performance during the whole oil drain process to offset damage from heat and friction over time.
To optimize the maintenance of each component and assure a constant level of comfort, it is essential to lubricate all moving surfaces.
Better transmission component protection and longer life are among the advantages of using extreme pressure (EP) and anti-wear additives.
Excellent seal performance aids in the prevention of oil leaks, lowering repair expenses.
Completely free of chlorine and heavy metals for enhanced environmental compatibility – easier waste oil disposal and recyclability.

Allison TranSynd
Friction modifiers, anti-wear chemicals, antioxidants, dispersants, detergents, rust/corrosion inhibitors; seal swell agents, anti-formants and more are all examples of conventional transmission fluids. Conventional fluids do not have the same thermal resistance as TranSynd because they are petroleum-based. Petroleum-based fluids degrade more rapidly and severely with extended usage, overburdening the dispersants and detergents’ efficacy. The oil thickens and becomes more acidic as a result of oxidation. Mechanical stress generates shear, causing permanent viscosity loss. Oil reduction means less lubrication. Sludge and varnish buildups reduce shift quality and clutch durability, resulting in greater component wear.
On the other hand, TranSynd is created from pure synthetic lubricants with inherent thermal and viscosity benefits. Performance additives are then tailored to the specific molecular structure and outstanding antioxidant qualities, resulting in a lubricant that is far more chemically and physically stable than other oils and practically unbreakable to shear.
Nothing protects better
The fluid in an Allison transmission is more than just a lubricant; it’s also a vital component of the system. It transmits electricity from the engine to the driveshaft, removes heat, lubricates, seals, protects, and maintains constant friction properties between friction plates and reaction plates. In all areas, TranSynd outperforms other automatic transmission fluids.
Liquid asset
TranSynd can assist you lower maintenance and downtime expenses by significantly increasing drain intervals. Transmission fluid, replacement filters, discarded and hazardous fluids are all saved on in this way. Most importantly, your Allison Automatic benefits from reduced wear, enhanced performance, and longer service life as a result of TranSynd’s superior lubricating protection. The end result is more production and less operating costs.
Features
- Providing superior wear resistance
- Protecting other transmission components
- Improving viscosity stability
- Allison Approved and Branded
- Resisting oxidation and sheardown
What is automatic transmission fluid?
In automobiles with automatic transmissions, the purpose of automatic transmission fluid (ATF) is to lubricate bearing surfaces and dissipate heat. To accomplish these tasks, automatic transmission fluid must have a particular viscosity that fits the transmission. It also has to be robust; it can’t break down when it’s hot or under pressure.
Different automatic transmissions have different requirements. In the last 50 years, automobile construction and materials has evolved considerably. Manufacturers use a variety of techniques, and many American vehicles are unable to use the same automatic transmission fluids as cars from Europe or Asia.
One golden rule when it comes to automatic transmission fluid is that you should always use the grade recommended by the manufacturer of your automobile. It’s not a smart idea to ignore it. Unfortunately, names, codes, and packaging may all be perplexing.

Choosing an automatic transmission fluid
You can’t mix and match conventional and synthetic ATFs of the same type, but you may not exchange grades.
There are at least 20 distinct types of automatic transmission fluids, each with its own set of characteristics. Some, such as Nissan Matic D, K, J, and S, are designed specifically for a certain automaker. Aftermarket companies have names like Multi-Vehicle ATF. So how do you figure out which one to choose?
You’ll have a lot more options if you’re purchasing a vehicle manufactured before 2006, particularly a classic. For cars produced after 2006, you can generally choose between synthetic or conventional automatic transmission fluids. You may get the manufacturer’s recommended brand from an automobile dealer (usually the more expensive option), or you can buy an aftermarket brand online or from a local car components store.
We can’t make any specific recommendations because there are too many car models to address. However, if you’re looking for the most certain protection, stick with the manufacturer’s recommended brand. Traditional or synthetic automatic transmission fluid is a personal decision. Synthetic ATF is more resistant to heat and friction than traditional ATF, which means it’s generally a cheaper option. Synthetic ATF is particularly popular among people who frequently tow a trailer, putting additional strain on its transmission.
Final Word
Both Castrol and Mobil chemicals that have been assigned the TES-295 seal of approval will display the Allison logo to indicate they are genuine Allison approved products. Many firms try to pass off their goods as “suggested for use” by using words like “recommended for use.” Fill in the blanks with TES-295, DEXRON, MERCON, or another specification. This statement is only meant to convey that their product has been “tested” and found to comply with the requirements, so perhaps it does, maybe not. They do not provide any documentation to prove this claim. However, because a company uses a logo to identify the authenticity of its goods, it may be protected by trademark or copyright laws.
