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.

Does transmission fluid have viscosity?

These gearboxes require fluids classified as GL-5. Besides the GL classification, the Society of Automotive Engineers (SAE) sets standards for the viscosity of transmission fluids as well. A fluid can, for example, have a 75W90 viscosity.

Is ATF 4 high or low viscosity?

It has excellent low temperature fluidity and viscosity breakdown performance over previous generation FCA ATF fluids. Havoline ATF+4 Automatic Transmission Fluid is specially formulated to give outstanding protection in critical areas of FCA transmission operation.

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.

Can I use motor oil for transmission fluid?

Yes, you can use motor oil instead of automatic transmission fluid. However you can’t do it if you expect the transmission to get you home or at a minimum you can’t to that if you can’t afford to install a new transmission and want to continue driving.

What viscosity is dexron ATF?


Brookfield Viscosity @ -40 C, mPa.s, ASTM D2983 11500
Color, Visual Red
Flash Point, Cleveland Open Cup, °C, ASTM D92 220 (428)
Kinematic Viscosity @ 100 C, mm2/s, ASTM D445 5.83

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.

Does transmission fluid lose 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.

How can you tell the difference between transmission fluid and oil?

The easiest way for you to tell the difference between transmission fluid and engine oil is the colour. Engine oil is typically an amber colour while transmission fluid is normally red.

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. … Low viscosity transmission fluid offers better performance and fuel efficiency gains.

What is an example of high viscosity?

Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly; high viscosity fluids move sluggishly and resist deformation. Some liquids, like pitch, glass and peanut butter, have such high viscosity they behave like solids. … For example, water at 20°C has a viscosity of 1.002 cPs.

What is ATF made of?

Traditional Transmission Fluid. While traditional transmission fluid is made from crude oil and the reshaping of hydrocarbons for specifications of different vehicles, synthetic transmission fluid is created through different chemical reactions.

What kind of transmission fluid does a TH400 take?

It might appear that Dexron VI would therefore be backwards compatible as far back as the older TH350 and TH400 transmissions. The reality is that Dex VI is best only for newer vehicles.

Why is my transmission fluid milky pink?

The milky substance you are seeing on the transmission dipstick is a result of cross-contaminated coolant and transmission fluid. More than likely, your radiator has failed which has allowed coolant to enter the transmission system. When coolant enters the transmission, it will cause failure very quickly.

What is Valvoline ATF?

Valvoline ATF is a multi-vehicle transmission fluid that provides outstanding protection and lubrication of the automatic gearbox over a wide temperature range. Formulation contains unique sealing conditioner that prevents seals from cracking which would otherwise result in leaks.
