What is the viscosity of Dexron 3?

What is the viscosity of Dexron 3?

GM: DEXRON-III, DEXRON-II, DEXRON-G34447. FORD MERCON: M-980508….Performance Specifications.

What viscosity is Dexron transmission fluid?

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.

What viscosity grade is ATF?

Automatic Transmission 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.

Is Dexron VI low viscosity?

This product is a low viscosity, full synthetic ATF built for the following core performance specifications: GM DEXRON VI.

Is dexron 3 the same as ATF?

ATF Dexron-III is an automatic transmission fluid formulated to meet the requirements of the General Motors Specifications GM 6297M for a Dexron®III Fluid and Ford Mercon® for Ford transmission.

What is viscosity index?

The viscosity index (VI) of a lubricant is the rate of the viscosity change due to a temperature change. To know if a lubricant meets the asset’s requirements based on the operating temperature range, you must understand the VI.

Is dexron III synthetic?

Castrol ATF Dex III is a synthetic based product which was originally designed for use in pre 2005 automatic transmissions fitted to General Motors vehicles. Due to it having a high viscosity index it is specified for many industrial and offshore applications where Dexron II or III or Mercon performance is required.

What is low viscosity transmission fluid?

Better technology. 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 Thicker transmission fluid better?

Proper Viscosity 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.

Is DEXRON 3 still made?

All Dexron-III (H) licenses expired permanently at the end of 2011, and GM now supports only Dexron-VI fluids for use in their older automatic transmissions. Aftermarket fluids asserted by their manufacturers to meet Dexron-III(H) and earlier standards continue to be sold under names such as Dex/Merc.

How do you read a viscosity chart?

Again, the lower the number, the lower the viscosity of the oil and the faster the oil will move around the engine. As an example, let’s compare 5W-20, 5W-30 and 10W-30 motor oils. A 5W-20 and 5W-30 will have very similar if not equal viscosity at lower start-up temperatures.
