TTA-44, TTA-46
Automatic transmission antifriction treatment


TTA-44 and TT4-46 are the most complete and the best performing antifriction treatments for automatic transmissions on the market. Their advanced formula, developed in collaboration with transmission professionals and specialists, enhances the quality and performance of all automatic transmission oils, whether mineral or synthetic. The TTA-46 is specifically formulated for automatic transmissions in CHRYSLER, HONDA, ACURA and TOYOTA vehicles.

Characteristics and Benefits

The high quality components of the TTA-44 and TTA-46 antifriction treatments include friction modifiers which adjust friction characteristics, thus ensuring optimal automatic transmission performance. When added to oil, TTA-44 and TTA-46 reduce friction and wear, prevent the development of metal dust, facilitate operation in freezing temperatures, allow smoother and faster gear shifting in addition to better power transmission.

When used in a preventive manner, the TTA-44 and TTA-46 antifriction treatments provide added protection against filth and varnish deposits around the control valves. They contribute to lowering the operations temperatures, provide excellent thermal stability, increase resistance to oil oxidation and protect the system against corrosion.

Types of Application

Use TTA-46 in automatic transmissions of CHRYSLER, HONDA, ACURA and TOYOTA vehicles. For all other manufacturers, use TTA-44.


The TTA-44 and TTA-46 antifriction treatments are compatible with all mineral and synthetic oils.

Directions for Use

Substitute 350 ml of your automatic transmission oil with 350 ml of TTA-44 or TTA-46. For maximum efficiency, add this antifriction treatment to new oil (ATTENTION: read warning section below carefully) and change oil filter if necessary. A bottle of 350 ml of TTA-44 or TTA-46 will treat as much as 14 L of transmission oil. 

When the manufacturer recommends the use of an automatic transmission fluid in a manual transmission, use the Antifriction Treatment for Manual Transmission TD-22.


The TTA-44 and TTA-46 replace the following Prolab product: TTA-40 (automatic transmission).

Adding the antifriction treatment to transmission oil may darken its original color without modifying its properties.

Available Sizes

350 ml, 4 L, 20 L, 55 L, 205 L
