Wynns Automatic Transmission Treatment

Wynn's Automatic Transmission Treatment is a fully synthetic formula to meet today's advanced transmissions requirements. When adding this product to a common multi-vehicle ATF fluid, it can increase the fluid performance to match most of the OEM's highly friction modified specialty fluids.
Wynn's Automatic Transmission Treatment also contains Wynn's proprietary Shudder Guard® additive which stops gear shudder almost instantly.
Wynn's Automatic Transmission Treatment is compatible with both mineral and synthetic ATF's.
Wynn's Automatic Transmission Treatment is not designed for constant velocity transmission (CVT) which requires different frictional characteristics.
Wynn's Automatic Transmission Treatment has also been designed to stop and prevent seal leaks in automatic transmissions, and to condition automatic transmission fluids to prevent and correct deposit-caused automatic transmission problems.

Advantages

• Stop and prevent leaks due to drying or shrinking seals.
• Maintain automatic transmission performance in service.
• Fight automatic transmission fluid breakdown due to heat and oxidation.
• Revitalize seals and O-rings to maintain internal pressure.
• Prevent oxidation and extend fluid life.
• Smooth transmission operation.
• Keep transmission clean.
• Stop and prevent rough shifting.

Background

Modern advance passenger car transmissions are controlled by sophisticated electronics, requiring special automatic transmission fluids (ATF). One of the critical specifications for modern ATF is friction performance. Energy saving Lock-Up torques Converters require friction modifier (FM) additives to ensure proper engagement of the active clutch pack. Not enough FM will lead to the infamous "shudder". Various OEMs have developed their own fluid specifications to suit their transmission design and to overcome shudder problem. Many of them market their own brands of fluids so that they can be sure of right lubricant characteristics. As a result, there are continuing new specifications and products released to the market place which make independent workshops or dealers hard to keep up to date. Many of them, though, are overlapped.
Hence, multi-vehicle ATF's are developed and offered to the market by oil companies and special lubricant companies. They are formulated with the common transmissions in mind and meet most of the specifications. But for many transmissions, the FM in these fluids may not be sufficient to meet the friction requirements. By adding Wynn's Automatic Transmission Treatment into these ATF's, the fluids can be improved to perform much closer to most of the OEM's highly friction modified specialty fluids.
On the other hand, FM additives can be depleted over time due to the mechanical action and heat. There is a need to replenish FM of the transmission fluid at the time of service. Wynn's Automatic Transmission Treatment is the ideal product for this purpose, especially when the customer notices a shudder problem.
Wynn's Automatic Transmission Treatment has been fully tested in various fluids as in the following list. Other fluids not in the list but similar are expected to have the same result.

• Corrects seal leaks caused by shrunken seals.
• Does not adversely affect the elasticity properties of new transmission seals.
• Supplements the seal swell properties of drainable used fluid during a fluid change.
• Maintains new seal pliability over a longer interval.
• Compatible with factory approved automatic transmission fluids.

• Maintains automatic transmission cleanliness, thereby helping to assure transmission life and performance.
• Removes existing deposits, thus helping to restore proper automatic transmission operation.
• Supplements the detergent/dispersant properties of un-drainable used fluid during the fluid change.
• Helps assure proper transmission lubrication by removing and preventing the accumulation of deposits.

• Retards automatic transmission fluid oxidation and the resultant formation of deposits which can impede proper transmission operation.
• Provides additional protection to automatic transmissions operating under high temperature conditions, such as trailer towing.
• Increases the life of automatic transmission fluids.
• Supplements the oxidation inhibitor properties of un-drainable used fluid during a fluid change.

• Protects internal automatic transmission surfaces against rust and corrosion problems, caused by condensation and oxidation by-products.
• Supplements the corrosion inhibitor properties of un-drainable fluid during a fluid change.

• Prevents automatic transmission wear between opposing metal surfaces without adversely affecting transmission shift points.
• Supplements the anti-wear properties of un-drainable used fluid during a fluid change.

Technical Data

The addition of the properly formulated package of Wynn's Automatic Transmission Treatment will enhance the seal-swell properties of both new and used transmission fluids.
For an automatic transmission fluid to become qualified originally, it must provide some minimal level of seal-swell. This is achieved typically by adding sufficient seal-swell additive to ensure a controlled amount of seal-swell. With too little swell, the seals might permit leakage and loss of the fluid.
As the automatic transmission fluid becomes oxidized in use, it tends to increase in its seal swelling characteristics, but not fast enough to keep pace with changes in the seals themselves. The seal materials, of course, also oxidize and age with heat. They tend to become hard and brittle. It has been found, over the several decades of automatic transmission cars, that supplemental seal-swell additions can keep the seals soft and pliable.
In cases where seals just begin to leak through aging, the added seal-swell can effectively soften them to stop the fluid loss. However, if the seals are allowed to wear excessively or crack, the only effective correction is replacement of the seals.
