What weight oil is transmission fluid?

Transmission Fluid is essentially thin hydraulic oil. In order to effectively lubricate the delicate parts of the system, the viscosity of the oil is kept low – generally around 0W/5 or 5W/10. Most importantly it needs to be relatively free flowing in order to transmit power from the engine to the transmission.

What is the viscosity of dexron III?

Performance Specifications


Is ATF low viscosity?

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. On top of calling for thinner fluid, some OEMs have extended their recommended drain intervals.

What type of automatic transmission fluid should I use?

Dexron III/Mercon – This is one of the most common fluids on the market. Most GM and Ford units call for this type of ATF, as well as many imports. If your owners manual recommends any form of Dexron, or any Mercon – other than Mercon V – this is the fluid you want.

Is differential oil the same as transmission fluid?

Differentials use gear oil/fluid. A manual transmission also uses gear oil but the viscosity may be a bit different. In an automatic transmission, definitely not; the fluid is much thinner and is called ATF – automatic transmission fluid.

What viscosity is transmission fluid?

What is the difference between dexron III and dexron VI?

But to mention the biggest difference between Dexron-III and VI is that of “viscosity”. Dexron-VI is much thinner. With the less updated base, Dex-III provides less shelf life than VI.

Is dexron 3 the same as ATF 4?

Dexron IV was an upgraded version of Dexron III, which was used by GM only briefly. … GM considers Dexron VI to be “backward compatible,” meaning GM recommends it for use in any vehicle that originally used any earlier version of Dexron and that it can be mixed with them.

What is low viscosity transmission fluid?

To conform with global trends, Totachi low viscosity ATFs are low viscosity fluids which reduce inner resistance loss, thus decreasing fuel consumption. Totachi low viscosity ATFs provide full protection of all parts and reliable performance of automatic transmission in high loads.

What is a good viscosity index?

Typical mineral-oil fluids used in hydraulics have a viscosity index of around 100, although products range from below 100 to well beyond 200. The best oils with the highest VIs remain stable and don’t vary much in viscosity over a wide temperature range.
