Your vehicle’s transmission relies on fluid to keep its components lubricated and running smoothly. When a transmission fluid leak occurs, it can lead to serious mechanical issues, costly repairs, and even complete transmission failure if left unchecked. At Interstate Automotive, we provide expert transmission fluid leak repair in the greater Olympia, WA area. Here are five signs that your vehicle may be losing transmission fluid. Puddles of Red Fluid Under Your Car One of the most obvious signs of a transmission fluid leak is a puddle of red or brown fluid forming beneath your vehicle. Transmission fluid is typically bright red when fresh, but it can turn darker brown as it ages. If you notice an oily spot in your driveway or garage, it’s important to determine whether it’s transmission fluid or another type of automotive fluid. If you suspect a leak, have a professional inspect your vehicle to locate and repair the source of the problem. Difficulty Shifting Gears Low transmission fluid levels can lead to sluggish, rough, or delayed gear shifts. Transmission fluid plays a vital role in creating hydraulic pressure for smooth gear changes, so difficulty in shifting could be a warning sign of a possible leak. Burning Smell Coming from the Engine If you detect a strong burning odor while driving, it could be due to overheating transmission fluid. When fluid levels drop due to a leak, the remaining fluid may overheat as it struggles to keep the transmission cool and lubricated. If this issue is not addressed quickly, it can cause severe damage to the transmission. Unusual Noises While Driving A healthy transmission should operate smoothly and quietly. If you begin to hear whining or grinding sounds, it could be a sign that your transmission fluid is low due to a leak. These noises typically indicate that metal components within the transmission are not receiving adequate lubrication, leading to increased wear and tear. Transmission Slipping or Hesitation Transmission slipping occurs when the transmission fails to stay in the correct gear, causing a sudden loss of power or erratic shifting. This can be especially dangerous when driving at higher speeds or merging onto highways. When transmission fluid leaks, the hydraulic pressure needed for proper gear engagement diminishes, leading to slippage or hesitation.

Regular oil changes are one of the most important aspects of vehicle maintenance. Motor oil keeps the engine running smoothly by lubricating its moving parts and reducing friction. Over time, oil breaks down and becomes less effective, which can lead to serious engine problems. Staying current with oil changes helps ensure that your vehicle runs efficiently and lasts longer. At Interstate Automotive, we provide oil changes in the greater Olympia area. Here are four reasons why keeping up with oil changes is essential. Prevents Costly Engine Damage Engine components move at high speeds and generate significant heat. Without clean and effective oil, these parts can wear out quickly due to increased friction. Old, dirty oil loses its lubricating properties and can lead to overheating and engine failure. The cost of an oil change is minimal compared to the expense of repairing or replacing an engine. Staying on schedule with oil changes helps protect one of the most vital and expensive parts of your vehicle. Improves Fuel-Efficiency When oil becomes old and sludgy, the engine has to work harder to perform its functions. This extra effort means the engine consumes more fuel, leading to decreased gas mileage. Clean oil allows the engine to operate efficiently, helping you get the most out of every gallon of fuel. By keeping up with regular oil changes, you can save money at the gas pump. Enhances Engine Performance A well-lubricated engine runs more smoothly and efficiently. Over time, dirt, debris, and sludge build up in the oil, causing the engine to work harder and reducing performance. Fresh oil keeps internal parts cleaner, allowing them to function better. This leads to smoother driving and improved vehicle performance. Keeping up with oil changes helps ensure that your engine operates at its best for as long as possible. Maintains Warranty and Resale Value Many vehicle warranties require regular oil changes as part of the maintenance agreement. Failing to follow the recommended service schedule could void your warranty, leaving you responsible for costly repairs. Also, if you ever plan to sell your vehicle, a well-documented maintenance history, including regular oil changes, can increase its resale value. Prospective buyers are more likely to pay a higher price for a car that has been well cared for.

Your vehicle's suspension system plays a critical role in enabling smooth and safe driving. It absorbs shocks from the road, maintains tire contact with the pavement, and supports proper steering control. But as they get older, components of the suspension system can wear out or get damaged, leading to noticeable issues. Recognizing the warning signs early can prevent more significant problems. At Interstate Automotive, we provide expert suspension repair in the greater Olympia area. Here’s a look at five signs of suspension trouble. Excessive Bouncing or a Rough Ride If you start feeling every bump and dip in the road, your suspension may be to blame. A properly functioning suspension system should settle quickly after bumps. Worn-out shocks or struts can make your vehicle feel excessively bouncy or unstable, especially when driving over uneven surfaces. Drifting or Pulling During Turns When your car leans heavily to one side during turns, it’s often a sign of worn-out suspension components. A failing suspension system can no longer keep the vehicle stable, making it harder to maintain control during sharp turns, which can pose a safety risk. Uneven Tire Wear When the suspension system isn't holding the car evenly, it can cause inconsistent tire contact with the road. This can lead to one side of the tire wearing out faster than the other. If you notice unusual tread patterns or bald spots on your tires, it’s time to have your suspension checked. Nose Diving When Braking If the front end of your vehicle dips excessively when you hit the brakes, it’s a sign of worn shocks or struts. A healthy suspension system should keep your car balanced during sudden stops. Nose diving can increase stopping distances and reduce braking efficiency, putting you at greater risk of accidents. Strange Noises When Driving Over Bumps Unusual noises—such as clunking, knocking, or squeaking sounds—are often associated with suspension problems. These sounds usually occur when driving over rough terrain and may indicate worn-out bushings, broken springs, or damaged shock absorbers.
