Quick Answer: What viscosity is transmission fluid?

What weight of 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.

Is ATF low viscosity?

To conform with global trends, Totachi low viscosity ATFs are low viscosity fluids which reduce inner resistance loss, thus decreasing fuel consumption. … These fluids can be used in AISIN-WARNER transmissions with JWS 3324 or NWS-9638 specifications requirements.

What thickness is 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 the typical viscosity of automatic transmission fluid?

Is there a difference between transmission fluid and transmission oil?

The simplest answer to the difference between transmission fluid and gear oil is in the purpose for which they are designed. Transmission fluid is engineered to work with automatic transmissions, whereas gear oil is typically intended to work with manual-type gear boxes.

Can transmission fluid lose its viscosity?

In order to improve fuel economy, original equipment manufacturers, OEMs, have introduced lower viscosity automatic transmission fluids. … Comparison of traditional viscosity ATFs to newer, lower viscosity ATFs. Traditional oils exhibit shear-down, the permanent loss of viscosity during use, by as much as 2 cSt at 100C.

What is an example of high viscosity?

The resistance to such flow is called the viscosity. Liquids which flow very slowly, like glycerin or honey, have high viscosities. … Honey, mostly glucose and fructose (see image below) is a good example of a liquid which owes its viscosity to hydrogen bonding.

What’s the difference between ATF and hydraulic oil?

ATFs are usually less viscous and designed to work under lower pressures and temperatures than hydraulic fluids. The operating temperature range of hydraulic fluids is larger i.e. they maintain their viscosity better in a broader temperature range. … ATF is very complex fluid compared to normal hydraulic fluids.

What is compatible with Type F transmission fluid?

Mobil Type F ATF is recommended by ExxonMobil for use in applications requiring Type F fluid as follows: Automatic transmissions in certain older Toyota, Mazda, Volvo, and other imported vehicles that require an ESW-M2C33-F fluid. In addition, this type of ATF is specified for some Ford power steering systems.

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.

What should my transmission fluid look like?

Healthy transmission fluid should be relatively clear or pink in color. If your transmission fluid is deep red or brown, your transmission fluid is old and most likely causing extra damage within your transmission. If it is dark brown, that is a sign you have burnt transmission fluid from overheating.

How do you know if your low on transmission fluid?

Symptoms of Low Transmission Fluid

  1. Drips or puddles underneath the car.
  2. Difficulty shifting through gears and/or slipping.
  3. Shuddering or shaking.
  4. Lurching or sudden jerks.
  5. Transmission won’t engage.
  6. Humming or clunking noises.
  7. A burning smell.

What is the difference between Type F and dexron transmission fluid?

What is the difference between DEXRON® III/MERCON® and type F transmission fluid? The Valvoline Type F transmission fluid is a high quality NON-friction modified fluid. DEXRON® III/MERCON includes friction modifiers in the fluid additive package.
