What kind of oil goes in a 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. However, a manual transmission fluid is typically the most optimal for manual transmissions.
Is there trans fluid in a manual?
Manual transmissions use a variety of oils: regular motor oil, heavyweight hypoid gear oil or even automatic transmission fluid in some cases. Your owner’s manual will tell you what your transmission calls for.
Is ATF bad for manual transmission?
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.
What is 80w90 gear oil used for?
The oil known as 80W-90 GL-5 is a lubricant for the gears in your vehicle. It is used in automatic and manual transmissions, and assists the gears in shifting smoothly.
Which oil is used in 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 happens if manual transmission fluid is low?
A low level of transmission fluid will make changing gears feel more sluggish and difficult. As time goes on, the gears may do the opposite by changing too quickly instead of too slowly. Either way, this will make it dangerous to drive because you won’t be able to change gears at the appropriate time necessary.
Do manual cars have clutch fluid?
Cars with manual transmissions have a clutch system that is operated by a master and slave cylinder, which both have clutch fluid running through them for lubrication. This is what causes the clutch to disengage from the flywheel allowing it to switch gears.
What is 90w gear oil?
It has been designed to reduce friction & wear, perform under the highest levels of heat & stress, and is recommended for use in differentials, manual transmissions, worm gears, power dividers, supercharges, and all gear boxes that require a gear lubricant.
Is it bad to mix gear oil?
Mineral oils, PAOs and esters may all be mixed together. Only polyglycol type synthetic oils (PG or PAG) may not be mixed with the other lubricant types. They can react together and form gum gels in the casings. Furthermore, they can sometimes be incompatible and immiscible with other polyglycols.
What is the viscosity of 80w90?

What is 90 weight gear oil used for?
The 75W-90 gear oil is used under extreme pressure conditions and is recommended for limited-slip differentials and for use in colder climates. Used in heavy duty manual transmissions, final drives and axles, high temperatures will not effect the heavy film left by this oil.
What are the symptoms of low clutch fluid?
The gears are grinding. Low clutch fluid can make shifting a struggle. Inadequate fluid levels will not allow the clutch to release properly. This can cause a loud grinding sound when you attempt to shift. It may be tempting to just top-off the clutch fluid, but that may not resolve the issue if there is a leak.
What kind of oil do you put in a BMW transmission?
BMW recommends using only the same fluid in the transmission when topping off the oil level. They do not recommend mixing ATF oil brands and specs so keep track of what oil is in your transmission.
What kind of oil do you put in a BMW 325e?
If no label is present, the official recommendation is any GL-4 gear oil. Our favorite is the Red Line MTL. However, some transmissions will have an orange ATF label and you should use a Dexron III ATF fluid. The 1984-1986 325e/528e should have a green “Special Oil” label on the transmission.
What kind of oil does a vintage BMW use?
Note: for the purposes of this page, “Vintage” refers to all BMW cars built up to and including the E30 3-series. Most manual transmissions on vintage models do not have a fluid label on the transmission because nearly all gearboxes took the same fluid – a universal GL-4. If no label is present, the official recommendation is any GL-4 gear oil.
What kind of oil does a SMG transmission use?
SMG transmissions use the same MTF oil as the manual transmissions, however, the SMG Hydraulic Pump uses Pentosin CHF 11S hydraulic fluid. Recommended replacement interval: 30,000-40,000 miles Shop MTF for BMW Manual Transmissions:
