Ok, now we have a general idea about when to replace transmission oil. Compared to engine oils, transmission oils are of higher viscosity. Both the oils have different additives. A manual transmission is made up of different metals, and rubber parts.
The gears can be made out of steel, transmission synchronizers can be made out of softer metal like Brass. Therefore, a big part of selecting the right transmission oil is to find the compatible oil. This can be done by knowing the GL rating of gear oils. GL-4 is typically used in regular cars for daily usage. The GL-5 is recommended to high-stressed gearboxes in trucks and high power output cars.
On checking the manual, you might find MT-1 rating recommendation. MT-1 grade oil is used in non-synchronized type gearbox.
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. Automatic transmission fluid, commonly referred to as ATF, ensures proper operation, performance and protection of the automatic transmission. This fluid is generally red in color with the exception of the fluid made specifically for Continuously Variable Transmissions CVTs.
CVTs have continuously changing speed ratios unlike typical automatic transmissions which have distinct gear shifts. CVTs can also help improve fuel economy.
Hybrid vehicles are commonly equipped with CVTs and they are occasionally used in non-hybrids. A CVT-specific fluid should always be used to ensure proper performance and protection. The type of transmission fluid you should use depends upon the make, model and year of your vehicle. Many automatic car owners wonder if they can use an automated manual transmission oil in an automatic gearbox.
Discover the answer in this article. Semi-automatic transmissions SAT or automated manual transmissions AMT use the same clutch and gear setup as manual transmission systems, but the switching and the operating of the clutch is automated. The complete process of opening the clutch, switching to another gear, and closing the clutch is electronically controlled. Their fuel efficiency evens top that of manual transmissions.
Because the design and technology is rather simple, they are also fairly inexpensive to repair. Manual transmission are used to limit the internal temperature, protecting the car from overheating.
Secondly, it is used for lubrication purposes, avoiding wear and tear of the gears. Over time, manual transmission fluids get contaminated with scrapes of metal and other debris as the transmission components such as the gears and bearings slowly deteriorate. This will affect the quality of the fluid and in time even damage your engine. That is why it is important to regularly check your car fluid. Since the fluid in manual transmissions is rather difficult to check, we advise you to have it done by a qualified car mechanic.
Automatic transmission fluids is more prone to heating up and breaking down than manual transmission fluids. And as with manual transmission fluid, metal debris from engine parts can contaminate the fluid, causing potential damage to your engine. Make sure to regularly check the fluid quality by using a transmission dipstick.
Although automatic transmission fluid is easier to check than manual transmission fluid, we advise you to check your manual or contact your trusted car mechanic.
Originally, manual transmission fluid had a very low viscosity. Over time, the viscosity, or lubricating ability, of the transmission fluid degrades and thins, as well. Synthetic transmission fluids are man-made, produced from refined oils treated with a variety of chemical additives. The synthetic transmission fluids have been shown to retain their viscosity longer than conventional transmission fluids so they don't have to be changed as frequently. The trade-off is that they cost more than the traditional transmission fluids.
Your vehicle manual will indicate which group is appropriate for the transmission in your car. There is no clear-cut consensus among drivers, mechanics or engineers which type of manual transmission fluid is best.
