The transmission fluid assist cool and lubricate your car’s transmission’s internal components. The transmission sends power from the engine to the wheels of the vehicle. An automatic transmission shifts the vehicle into different gears and this is dependent on the speed that you are driving. In an automatic transmission vehicle, the transmission system comes with an oil pan that contains the transmission fluid and fluid filter. The fluid provides the power/force needed to shift into different gears. In manual transmission vehicles, there is a case that has the transmission fluid.
In contrast with an automatic transmission, the fluid in a manual vehicle system is not directly involved in shifting gears, since it is a mechanical system, while an automatic transmission is operates on hydraulic. If an automatic transmission doesn’t have enough fluid, or the fluid has gotten contaminated, it is possible for the transmission to begin to slip and eventually fail. If a manual transmission does not have get fluid, or the fluid has become contaminated, it is possible for the transmission to get noisy, the internal components to wear out faster and eventually fail.
Facts to Note:
An automatic transmission fluid service will substitute the pan gasket, filter, and transmission fluid. Some cars do not have a serviceable transmission filter and some transmissions are meant to stay “sealed for life,” implying that they do not need any service or maintenance. Go through your owner’s manual for information on whether you have the sealed system or not.
In contrast to the automatic transmission, the manual transmission does not contain a filter, which implies that as parts wear, the transmission fluid gathers particles of metal and is unable to filter them. This is why it is very essential to carry out a transmission fluid service as per manufacturer recommendations.
How to Fix:
Drain your transmission fluid
(Automatic only) Install new pan gasket and filter (if replaceable)
Refill the proper type and quantity of oil/fluid for your transmission
Check for leaks
Test drive the car
It is advised that a car should have a transmission fluid replacement every 40,000 miles. If you observe any fluid underneath the vehicle, get it inspected as soon as you can. Replacing your transmission’s fluid frequently will greatly extend the service life of your cars’s transmission.
Common signs indicating you may need to replace the transmission fluid:
Car has a hard time running
Car stalls when going up or down a steep incline
Check Engine Light comes on
Transmission makes noise
How important this replacement:
The transmission fluid services are a great part of regular upkeep and will raise the service life of your transmission. According to the Automatic Transmission Rebuilders Association, 90% of automatic transmission failures are made by overheating and can be usually be blamed on transmission fluid that should have been replaced.
