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.

Why is my car struggling to start? Here are 4 common culprits

By Interstate Automotive • July 21, 2025
It’s incredibly frustrating to turn your key, only to find that your car is struggling to fire up. A car that struggles to start is not only inconvenient, but can also be a warning sign of underlying mechanical issues that need immediate attention. At Interstate Automotive, our local mechanics are experts at diagnosing and resolving problems that cause no-start. Here are four common reasons why cars struggle to start. Weak or Failing Battery One of the most frequent causes of startup issues is a battery that’s low on power or nearing the end of its life. Batteries tend to degrade over time, especially in extreme weather conditions. If you hear a clicking noise or the engine cranks slowly, your battery may not be delivering enough voltage to start the car. Corroded terminals or a loose battery connection can also prevent proper power flow. Testing and replacing the battery when needed is a simple and cost-effective way to restore reliability. Worn Out Starter Motor The starter motor is responsible for turning over the engine when you initiate ignition. If the starter motor is faulty, your engine may not crank at all. This issue often presents as a single click or no sound at all when you try to start the car. Since the starter is essential for engine ignition, a malfunctioning unit will likely require replacement to get your car back on the road. Fuel Delivery Issues Without proper fuel delivery, your engine can’t start. Problems with the fuel pump, clogged fuel filter, or a failing fuel injector can prevent the engine from getting the fuel it needs to smoothly fire up. If your car cranks but doesn’t catch, or it starts and immediately stalls, a fuel system issue may be to blame. Ignition System Problems Faulty spark plugs, ignition coils, or wiring issues in the ignition system can interfere with your engine’s ability to ignite the air-fuel mixture. If spark plugs are worn or misfiring, the engine may crank but fail to start smoothly or consistently. Keeping up with scheduled spark plug replacements and inspections helps maintain a dependable ignition system.

Helpful Tips for Keeping Your Transmission in Excellent Health

By Interstate Automotive • June 21, 2025
Your vehicle’s transmission is one of its most important components, responsible for transferring power from the engine to the wheels. If the transmission isn’t properly maintained, it can lead to costly repairs or even a complete failure. Fortunately, there are some simple steps you can take to help extend the life of your transmission and keep your vehicle performing at its best. Shift Smoothly and Responsibly One of the easiest ways to protect your transmission is to shift gears carefully. Whether you're driving a manual or an automatic, avoid aggressive acceleration or sudden shifts from drive to reverse or vice versa. Abrupt gear changes put unnecessary stress on internal components and can cause premature wear. If you drive a manual, be sure to match your engine speed with the correct gear to reduce strain. Avoid Overloading Your Vehicle Overloading your vehicle can significantly increase the strain on your transmission. Towing more than your vehicle’s rated capacity or hauling heavy loads on a regular basis makes the transmission work harder to deliver power. Excessive weight increases heat and pressure, which can lead to overheating. Always follow the manufacturer’s weight limits to avoid putting your transmission under undue stress. Keep an Eye on Warning Signs Your transmission will usually give you clues when something isn’t right. If you notice delayed shifting, slipping gears, grinding noises, or unusual vibrations, these could be early signs of a problem. Addressing transmission issues early on can often prevent more extensive damage and costly repairs. Stay on Top of Fluid Changes Transmission fluid plays a critical role in lubricating moving parts, regulating temperature, and enabling smooth gear shifts. Over time, the fluid can become dirty, reducing its effectiveness. Check your owner’s manual for the recommended service interval and have the fluid changed as needed. Schedule Regular Inspections Even if your vehicle seems to be running fine, it’s wise to have the transmission inspected during regular maintenance appointments. Mechanics can identify potential issues before they become serious and ensure that fluid levels, seals, and filters are in good condition. Preventive care can help your transmission last beyond the average lifespan.
