The average driver may not think about their car’s transmission. But whether you're maneuvering through city traffic, hitting the highway for a weekend getaway, or taking a leisurely drive around town, your transmission is hard at work.
Despite its critical presence, many drivers understand very little about this component. Read through the essential information you should know about transmissions to drive safely and have good maintenance habits.
Transmission Fluid: How To Check Fluid Levels
Transmission fluid cools the transmission and lubricates the gears. It’s vital for smooth shifting and regulating the transmission’s temperature.
To check your car's transmission fluid at home, start by parking on a level surface and warming up your engine for a few minutes. Then, locate the transmission fluid dipstick—usually near the engine.
Remove the dipstick, wipe it clean with a rag, reinsert it fully, then pull it out again to check the level. The fluid should be between the "full" and "add" lines.
In addition to the level, observe the fluid's color. It should be pink or red. If it's brown or smells burnt, it's time to replace the fluid altogether.
Driving Habits: How You Can Damage Your Transmission
Transmissions are tough, but consistently poor driving habits may cause premature degradation. There are several practices to reduce costly repairs and maintain a fully functional transmission.
Shifting from drive to reverse without coming to a complete stop can cause immediate, severe damage to the transmission. This action forces the transmission to act against the vehicle's momentum, leading to excessive wear or mechanical failure.
The parking brake is an effective tool that you should use whenever possible. Failing to engage the parking brake, especially on inclines, forces the transmission to bear the full weight of the vehicle. Over time, this pressure can lead to the degradation of internal components, increasing the risk of transmission slips or failure.
Transmission Cooler: Protecting Automatic Vehicles
An essential component that safeguards your transmission is the transmission cooler. While there are a few differences between transmission and engine oil coolers, transmission coolers focus on preventing premature wear and ensuring optimal performance.
Transmission coolers operate by circulating the fluid through a series of coils or tubes, allowing air to reduce its temperature. Modern cars already have a transmission cooler, but some drivers will upgrade the cooler if they frequently haul a trailer with heavy loads or drive in extremely hot climates.
Unusual Noises: The Sounds To Listen For
Identifying unusual noises early can prevent transmission failure. You just need to know what sounds to listen for when driving.
Whining and clunking noises accompanied by a gear-grinding sensation indicate low transmission fluid or worn-down parts. A noticeable buzzing or humming sound suggests abnormal friction or hazardous objects inside the transmission.
Grinding sounds while shifting are some of the most serious noises you can encounter. Their presence is an evident sign of a worn clutch in manual cars. For automatic transmissions, the sound could mean a fluid leak, degraded transmission fluid, broken parts, and more.
automotive knowledge that you should know about transmissions. Now, you can implement best practices, increase safety on the road, and drive a functional and efficient vehicle.
