Kia Transmission Maintenance

In continually transmitting power from the engine to the wheels, your gearbox is under huge pressure. While Kia transmissions are enormously durable and long-lasting, it pays to help with a few solid maintenance fundamentals. The following Kia transmission maintenance guidelines will keep your gears shifting smoothly, quietly, and promptly for many years to come.

Check Your Transmission Fluid Monthly

The remarkably complex interior of any modern transmission entails hundreds of parts that all need to be properly lubricated. Along with lubrication, transmission fluid helps reduce heat and maintains necessary hydraulic pressure. You should check the quality and level of our transmission fluid once a month to make sure it’s still up to the task.

Flush the Fluid Every 60,000 to 100,000 Miles

In modern transmissions, the fluid typically needs to be flushed and refreshed every 60,000 to 100,000 miles. This broad range makes monthly fluid checks so important. You and your technician will need to judge when it’s time for new fluid. As with all vital vehicle fluids, flushing too frequently is far healthier and safer than leaving it too long. 

Warm Up Your Car Before You Drive

Your daily driving habits have a big effect on the condition and longevity of your transmission. One excellent habit for both your transmission and engine is to allow your car to warm up for a few minutes before you start driving. This brings the motor oil and transmission fluid to an optimal temperature for lubrication.

Avoid Both Heavy Traffic and Heavy Towing 

Where possible, it’s best to avoid stop-and-go traffic, which puts a great deal of stress on the gearbox. Increasing the weight of the car with towing also creates strain. Of course, most Kias have excellent towing capacity, and you should take full advantage of this. Just be aware that the more weight any car tows, the tougher a time the transmission has.

Keep Your Engine’s Cooling System in Good Shape

The engine’s cooling system actually helps to control heat in the gearbox as well. So, for the sake of your car’s two most important components, always keep your cooling system and coolant in tip-top condition. Coolant usually needs to be changed every two years or 30,000 miles.
