What fluid 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.

Can you use ATF fluid in a manual transmission?

While some manual transmissions now use automatic transmission fluid (ATF), most manuals use a variety of fluids for optimal engine and gear function. ATF also works as a hydraulic fluid for power steering systems and some 4WD cases in automatic cars.

Is it bad to change manual transmission fluid?

Manual: Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Under heavy-duty use, some manufacturers suggest changing transmission fluid every 15,000 miles. The typical service interval is 60,000 to 100,000 miles. Changing it more often does no harm.

Will a manual transmission shift without fluid?

If there is no fluid, there is no hold, the gears cannot spin and therefore the car won’t be able to move. If your vehicle does get to the point of having no transmission fluid, you will likely also be looking at extensive repairs or even a full replacement of your transmission.

Is there a difference between automatic transmission fluid and manual transmission fluid?

Automatic transmissions use pressurized fluid to change gears. Automatic transmission fluid is hydraulic fluid. That’s one reason automatic transmission fluid has a lower viscosity than manual transmission fluid. Fluid that has accumulated foam can also fail in its role as a hydraulic fluid.

How long does manual transmission fluid last?

30,000 to 60,000 miles
Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Under heavy-duty use, such as towing or stop-and-go traffic, some manufacturers suggest changing transmission fluid every 15,000 miles.

What happens if you don’t change manual transmission fluid?

If you don’t change your transmission fluid frequently, the dirty fluid will not serve as an effective lubricant and it won’t disperse heat well. This will cause wear and tear on the clutches and other parts of your transmission.
