Manual transmission fluid should provide smooth shifting. It should be able to function over a wide temperature range, and should also help reduce gear noise. All transmission fluids should protect against oxidation and corrosion. At the same time, this corrosion protection shouldn't affect the balance of soft metals that are common to manual transmission synchronizers.

Any smart vehicle owner knows that better products--be it synthetic motor oil, bear lube, or air filters--yield better service from their equipment. Of course, you want to purchase the best quality products for your car, but you don't want to spend more than you need to. However, rather than focusing only on saving money on the purchasing end, think of the whole picture.

What are the total costs of cutting corners? If you purchase a cheaper manual transmission fluid, will it still provide the same level of performance? What will you end up paying farther down the road in terms of time wasted, extra fluid purchases as a result of shorter drain intervals, and repairs to your transmission?

The Difference that High-Quality Manual Transmission Fluid Makes

High-quality manual transmission fluids provide longer drain intervals. Immediately you have savings, because less fluid need be purchased. Also, a fluid made from high-quality synthetic base stocks and additives will improve your transmission's performance right there. However, if you're using bad fluid from the get-go, you're already undermining your vehicle's performance. A great transmission fluid can help you save on trips to the mechanic, trying to figure out the poor performance of your transmission.
