What is the typical viscosity of automatic transmission fluid?

What viscosity is automatic transmission fluid?

Low-temperature fluid viscosity requirements were established with a motor-driven 3-speed transmission apparatus. It is concluded that the current used-fluid Dexron viscosity limit of 5.5 cs minimum at 210 F provides a good safety factor for preventing excessive internal leakage at high temperatures.

Is ATF 4 high or low viscosity?

Havoline ATF+4 Automatic Transmission Fluid is formulated with high purity synthetic base stocks. It is designed to maintain its viscosity through excellent oxidation stability and use of long lasting viscosity modifiers.

What is the thickness of transmission fluid?

Your transmission fluid shouldn’t be too thick or sluggish. It should be pretty thin and less viscous than motor oil meaning thinner than motor oil. It is normal for the transmission fluid to get a little thicker over time through use.

What is Type A automatic transmission fluid?

Chalet Type A Automatic Transmission Fluid (ATF) is a high quality automatic transmission fluid composed of highly selective and refined base oils for maximum performance. It is especially designed for use in older car and truck transmissions.

What is low viscosity transmission fluid?

Low viscosity ATF is the cutting edge of ATF technology. It has active chemistry that allows it to not only last longer than high viscosity ATF but also protect the transmission for tens of thousands of miles.

Is dexron VI low viscosity?

BG DEXRON®-VI Low Viscosity Full Synthetic ATF offers dependable protection for most passenger and commercial automatic transmission applications where low viscosity fluids are recommended. By 2022, nearly 75 percent of passenger cars in the U.S. will require low viscosity automatic transmission fluid.

What is the weight of ATF fluid?

Should tell you everything you need to know and more. It has the viscosities of a couple brands of ATF. Mobil 1 Synthetic ATF is approx 10wt.

Which of the following was used in early automatic transmissions?

The First Automatic Transmissions

General Motors then developed the first automatic transmission using hydraulic fluid in the 1930’s, and introduced the “Hydra-Matic” transmission in 1940. The 1948 Oldsmobile was the first model to use a true automatic transmission.

Does transmission fluid get thicker?

Viscosity change: The viscosity of transmission fluid changes and gets thicker in the cold. … The fluid can also fail to lubricate parts when it is too cold, wearing parts down unnecessarily. This characteristic can be mitigated with synthetic fluid that is often less viscous in cold temperatures.

Is automatic transmission fluid a lubricant?

It’s another lubricant that is less known but necessary for any motor vehicle to function properly: transmission fluid. Transmission fluid, also called gear oil, ensures smooth functioning and extended life of transmissions, transfer cases and differentials in cars, trucks and other machinery.
