The transmission system is a critical component in your vehicle. When your car shifts gears, the transmission transfers kinetic energy from the engine to the wheels, allowing your car to move at various speeds. The transmission requires proper lubrication to function optimally and prevent overheating. It uses hydraulic fluid to lubricate the moving parts and ensure smooth gear shifts. The fluid may wear out over time due to leaks. Checking the transmission fluid can help identify leaks, prevent unexpected breakdowns, and avoid costly repairs. This guide highlights how to check your transmission fluid.
Why Check Transmission Fluid?

A vehicle’s transmission is a mechanical system with moving parts. It’s prone to friction and overheating, deteriorating the pan gasket, converter seal, or fluid line. If these components break or become too loose, the transmission fluid may leak, resulting in numerous problems.
Checking your vehicle’s transmission fluid is part of preventive maintenance. Adequate fluid levels keep the bearings cool and protect the clutch slip from damage caused by air bubbles. Proper lubrication also prevents avoidable damage resulting from worn-out debris, leading to long-term savings on repair costs.
When To Check Transmission Fluid
While auto experts suggest you check transmission fluid at least once monthly, the ideal time depends on several factors. Your driving habits, how often you drive your car, and the transmission system determine when to check the fluid levels. If you drive aggressively, you may have to check the fluid levels more often since this can adversely affect the transmission system. If you notice unusual noise, a burning odor, or difficulty shifting gears, it’s time to check your transmission fluid. Although an automatic transmission requires minimal attention, we recommend checking and changing the transmission fluid after 50,000 to 100,000 miles.
Preparation
Although checking your Kia’s transmission fluid may seem daunting, the process is straightforward. Prepare by parking your vehicle on level terrain and in a well-ventilated spot before engaging the emergency brake to allow the engine to cool. Gather all the necessary equipment, including the proper replacement fluid, funnel, and a dust coat or old clothes, since the task can be messy. Have a fire extinguisher within reach so you don’t take chances. Once these items are ready, you can move to the next step.
Locating the Transmission Dipstick
Every transmission system has a dipstick with markings for checking transmission fluid levels. The dipstick is usually beneath the vehicle, sticking out of the transmission. It has a longer handle than an engine’s oil dipstick and is bright red or yellow for easy identification. You can always check your car’s owner’s manual to locate the dipstick if you’re unsure where to find it. Depending on your vehicle’s model, you may have to open the hood or remove the engine cover to access it. If your car lacks a traditional dipstick, you may require help from an authorized service center.
Checking Transmission Fluid
Once you’ve prepared your vehicle and located the dipstick, checking the transmission fluid is easy. You don’t have to be a professional mechanic to perform this task. With your vehicle parked on flat ground, start the engine and let it run for about 10 minutes before proceeding with the check.
So, why check transmission fluid when the engine is running? The answer is simple. When the engine is warm, the transmission fluid expands, giving you a clearer picture of its precise level in normal operating conditions. A cold engine may inaccurately indicate that the fluid is low and requires replacement.
The next step is to pull out the dipstick and clean it before inserting it back into the transmission. Remove it again and check the level, color, and smell. The fluid should be pinkish and reach the Full mark on the dipstick. If it reads low, is dirty, or has a burning odor, it’s time to replace it. Use the funnel to add more fluid and repeat the steps above to re-check and ensure proper levels. Ensure that you don’t overfill since this can saturate the transmission.
Frequently Asked Questions
How Often Should You Check Your Vehicle’s Transmission Fluid?
You should check your transmission fluid at least once a month. This preventive maintenance will keep your vehicle running smoothly and prevent significant issues from developing, ensuring an enjoyable driving and car-ownership experience. It can also save you money in the long run by avoiding costly repairs.
What Color Should Transmission Fluid Be?
The color of the transmission fluid depends on the vehicle model. Healthy lubricant typically appears bright red or pink. A brown or black color indicates that it’s dirty and may need replacement. If it smells burnt, your system may have issues that need fixing.
Can You Inspect the Gearbox Lubricant When the Engine Is Cold?
Most vehicles need a warm, running engine for the best check and accurate results. A cold engine may inaccurately indicate that the fluid is low and requires replacement. Some models may need checking with the engine off. Check your owner’s manual to confirm if this is the case.
What if Your Car Has a Sealed Gearbox?
Sealed systems require professional inspection and fluid replacement since they don’t typically have a traditional dipstick. Unless you’re an expert, don’t attempt to open a sealed gearbox. Although some newer models use long-lasting fluid, sealed systems still require expert inspection and replacement when necessary to ensure optimal performance of your car.
