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.

4 Signs that Your Car Needs Brake Repair Now

By Interstate Automotive • October 24, 2025
Your vehicle’s brakes are one of its most critical safety systems, and any issue with them should be taken seriously. When brakes start to fail, stopping distances increase, handling becomes unpredictable, and the risk of accidents rises dramatically. Recognizing early warning signs can help you avoid costlier repairs and stay safe on the road. At Interstate Automotive, we provide expert brake repair in the greater Olympia, WA area. If you notice any of the following symptoms, it’s time to schedule professional brake service immediately. Strange Noises Unusual sounds coming from your brakes are one of the most common indications of trouble. A high-pitched squealing noise usually means the brake pads have worn thin. If the sound is more of a harsh grinding, it could mean the pads are completely worn out, and metal is scraping against metal. Continuing to drive with grinding brakes can damage rotors, so prompt attention is essential. Soft Brake Pedal If your brake pedal feels soft, spongy, or sinks quickly toward the floor when pressed, that’s a warning sign of a problem in the hydraulic system. This may be due to air in the brake lines or a fluid leak. A soft pedal means your brakes aren’t generating proper pressure, putting you at serious risk if you need to stop suddenly. If your car is leaking brake fluid, it’s a major safety hazard and best to get towed to the shop. Vibrations When you press the brake pedal and feel vibrations or pulsing, it often indicates warped rotors. This can happen from excessive heat buildup and uneven wear. Pulsing brakes reduce stopping efficiency, so it’s best to have a technician diagnose and resolve the issue as soon as possible. Warning Light on the Dashboard If your brake warning light appears on the dashboard, it’s your car’s way of alerting you to a potential issue. Even if the brakes feel normal, an illuminated light should never be ignored. A technician can run diagnostics to determine the exact cause and prevent a small issue from becoming a major one.

Don’t Overlook these Common Warning Signs of Engine Trouble

By Interstate Automotive • September 20, 2025
Your car’s engine is its heart, and when something starts to go wrong, the sooner you recognize the signs, the better. Ignoring potential engine trouble can lead to breakdowns, costly repairs, or even complete engine failure. While modern vehicles are built to be durable, they still need prompt attention when problems arise. At Interstate Automotive, we provide expert engine repair in the greater Olympia, WA area. Here’s a look at four common warning signs of engine trouble that you shouldn’t ignore. Strange Noises Engines are designed to run smoothly, so if you begin hearing unusual sounds such as knocking, grinding, or ticking, it’s a red flag. Knocking noises often signal worn-out bearings, while grinding may indicate a lubrication problem. Any strange or persistent sound under the hood deserves prompt attention from a mechanic to prevent more serious damage. Warning Lights The check engine light is one of the most common indicators of a problem, but other dashboard lights may also point to engine issues. While it can sometimes be triggered by something minor, such as a loose gas cap, it often signals issues with components like the oxygen sensor, catalytic converter, or ignition system. Ignoring warning lights can allow small problems to escalate into costly repairs. Discolored/Excessive Exhaust Smoke Your exhaust can tell you a lot about your engine’s health. Blue smoke may indicate oil burning, white smoke can signal internal coolant leaks, and black smoke often means too much fuel is being burned. Any unusual or excessive exhaust is a clear warning sign that your engine needs professional attention. Rough Idling Engines should idle smoothly, so if your car shakes, sputters, or stalls when stopped, there may be an issue with the fuel system, spark plugs, or airflow sensors. While it might start as a minor annoyance, rough idling can lead to more serious engine problems if ignored.
