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.

5 Warning Signs that It’s Time for Alternator Replacement

By Interstate Automotive • November 21, 2025
Your vehicle’s alternator plays a crucial role in keeping the electrical system running smoothly. It charges the battery and powers essential components like the headlights, dashboard lights, and power windows while the engine is running. When the alternator begins to fail, your car can quickly experience electrical issues and even lose power completely. At Interstate Automotive, we provide expert alternator replacement and auto electric repair in the greater Olympia area. Here are five common signs that it may be time to replace your alternator. Problems with Lights One of the most common signs of a failing alternator is dim or flickering lights. You might notice your headlights or dashboard lights growing noticeably weaker. Since the alternator powers your vehicle’s lighting system, inconsistent brightness often points to irregular power output. Weak or Dead Battery While batteries can wear out on their own, a weak or frequently dead battery can also be a symptom of a failing alternator. If you’ve replaced your battery recently but it continues to lose charge, your alternator may be the real problem. The mechanic can test your charging system to confirm whether the alternator is functioning properly. Unusual Sounds Under the Hood A failing alternator can produce unusual noises that indicate trouble. Grinding or whining sounds may come from a worn-out bearing or a belt issue in the alternator. Having the alternator inspected at the first sign of unusual noise can potentially prevent bigger problems. Warning Light on the Dashboard Modern vehicles often feature a dashboard warning light shaped like a battery or labeled ALT or GEN. When this light turns on, it’s a signal that your charging system isn’t working correctly. While this warning could indicate a battery problem, it frequently points to a malfunctioning alternator. Don’t ignore the light—have your vehicle checked by a professional to diagnose the issue before it worsens. Electrical Accessories Malfunctioning If your power windows, radio, or air conditioning begin to behave erratically, it could be due to inconsistent power supply from a bad alternator. The alternator may not be generating enough electricity to support all systems, especially when demand is high. When multiple accessories start acting up at once, it’s a warning sign that your alternator is no longer keeping up with your vehicle’s electrical needs.

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.
