Is transmission fluid thick?

What is the consistency of transmission fluid?

Identify the consistency and smell of the leaking fluid. Transmission fluid is a slick liquid that’s oily to the touch, much like engine oil or brake fluid.

Is transmission fluid thicker than engine oil?

Manual Gearbox

It’s much thicker than motor oil, with an average motor oil being 5W/30 and the average gear oil being 75/90 (see this article for in depth explanation of oil viscosity index).

What is the viscosity of transmission fluid?

ATF III – Mineral automatic transmission fluid

Temp. [°C] Dyn. Viscosity [mPa.s] Kin. Viscosity [mm²/s]
40 30.31 35.55
50 21.53 25.44
60 15.93 18.97
70 12.18 14.62

What happens if transmission fluid is too thick?

Transmission Fluid Leakage: Adding too much fluid will cause high pressure inside of your transmission. … Reduced Fluid Lubrication: Since the system will foam up, this will affect the ability to lubricate the transmission parts. This can cause wear and tear on your transmission and damage the system in the long run.

What should your 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.

Is Thicker transmission fluid better?

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 gearbox oil and transmission fluid the same?

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.

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.

Does transmission fluid lose viscosity?

Most modern transmission fluids have a few things in common: better heat and oxidation resistance, better shear stability so that the fluid doesn’t lose viscosity over time, and a lower coefficient of friction needed for locking torque converters on modern cars.
