Why do you need to change transmission fluid?
Here are 4 reasons why this process is so important for those with automatic transmissions: 1 It extends the transmission lifespan: If the transmission’s internal hydraulic lines are clogged, it can cause inner seals to break, which creates internal leaks and can lead to complete transmission failure. By having the fluid flushed and filters replaced every 30,000 to 50,000 miles, you significantly reduce the potential of damage and can extend its lifespan. 2 It improves smooth shifting: When transmission fluid is replaced and the fluid is flushed, it improves the efficient flow of transmission fluid throughout the system. The end result is that the transmission will shift smoother. 3 It is vital to protect warranties: Most new cars, trucks, and SUVs come with a powertrain warranty — which protects the engine, transmission and drive-system components. However, if those systems are not maintained as recommended, it can void most extended warranties and cost you a significant amount of money if you need to replace them. 4 It can improve fuel economy: A smooth-shifting transmission is also critical for the efficient operation of your engine. If the transmission slips or shifts higher than the engine is set, it can and often will burn more fuel inside the engine than it should. A transmission fluid change can contribute to optimal fuel mileage.
Why is a smooth shifting transmission important?
If the transmission slips or shifts higher than the engine is set , it can and often will burn more fuel inside the engine than it should. A transmission fluid change can contribute to optimal fuel mileage.

Grinding Noises in Transmission
One of the most common signs that you need transmission repair services in Las Vegas is the grinding noise coming from the component. Dirt, grease, and sludge can accumulate in the fluid. You can take a look at the color of the fluid to see if it’s red or brown. If it’s brown, then you can be sure that you need transmission repair and flushing.
Gear Shift Problems
Another common sign that there’s something wrong with your transmission is when you have trouble shifting gears. This happens when there are too much dirt and sludge accumulated in the transmission fluid. The fluid isn’t consumed. Rather it is burned. Its function is to lubricate the entire transmission system.
Slipping of Gears
Gear slipping occurs when the contaminants in the transmission fluid don’t allow proper flow. Without proper flow, the fluid isn’t able to build the pressure needed for gears to work properly. As a result, you get slipping gears. The slipping also occurs when the contaminants don’t allow the fluid to connect with the gears properly.
Surging Vehicle
Another common sign that you need to get your transmission checked for flushing is the surging of the vehicle. This occurs due to similar causes. The contaminants in the transmission don’t allow the fluid to disperse properly.
Delay in Movement
