What kind of fluid goes in a gearbox?

What kind of fluid goes in a gearbox?

For example, most modern gearboxes require a GL-4 oil, and separate differentials (where fitted) require a GL-5 oil. While they take the same form, the viscosity grades for gear oils are on a different scale than the viscosity grades for an engine oil. The viscometrics for gear oils are standardized in SAE J306.

What gear oil is recommended for manual transmission?

Commonly recommended manual transmission fluid formulations include SAE 80W, 75W-90, 80W-90 and SAE 90. In some cases, a multi-grade engine oil or automatic transmission fluid may be recommended.

Which gear oil is best for automatic transmission?

  • Honorable Mention.

Is transmission fluid same as gear oil?

Transmission fluid, also called gear oil, ensures smooth functioning and extended life of transmissions, transfer cases and differentials in cars, trucks and other machinery. Like motor oil, they are composed of base oil (mineral, semi- or fully synthetic) and additives.

How do you check the transmission fluid on a 2000 Mitsubishi Eclipse?

Transmission Fluid Level Check Mitsubishi Eclipse (2000-2005) Spyder GS 2.4L 4 Cyl.

  1. Remove Dipstick – Access point for transmission fluid.
  2. Check Level – Insert dipstick and pull it out to determine level.
  3. Add Fluid – Determine correct fluid type and add fluid.
  4. Replace Dipstick – Put the dipstick / cap back in place.

Can you use ATF instead of gear oil?

Incorrectly using ATF in a manual transmission or gear oil in an automatic transmission can severely increase the wear and tear. ATF does not have the thick lubrication qualities needed in a manual gearbox, and gear oil does not contain all the additives needed to smoothly run an automatic transmission.

Is all 80 90 gear oil the same?

Because the viscosity of gearbox and engine oils are measured on different scales, an SAE 80 gearbox oil is roughly equivalent in viscosity to an SAE 20 engine oil. An SAE 90 gearbox oil is roughly the same viscosity as an SAE 50 engine oil. Most manufacturers now offer EP80W/90 oils in place of both EP80 and EP90.

Can I use 80w90 instead of 10w40?

The most common mistake is the belief that the viscosity of SAE 80W gear oil is much thicker than the viscosity of SAE 10W-40 motor oil. This is absolutely incorrect!
