Transmission fluid is essential for keeping your vehicle shifting smoothly and protecting internal components from heat and friction. When a leak develops, fluid levels can drop quickly, leading to poor performance and potential transmission damage. Because transmission repairs can be expensive, recognizing the warning signs of a transmission fluid leak early can save you a significant amount of money. At A-1 Automotive, we provide expert transmission fluid leak repair in the greater Portland, OR area. Here are four warning signs of a transmission fluid leak. Reddish Fluid Under Your Vehicle One of the most obvious signs of a transmission fluid leak is finding fluid pooled beneath your car after it’s been parked. Transmission fluid is typically reddish when new and may turn darker brown as it ages. If you notice a puddle of such fluid where your car’s been parked, it’s important to have your vehicle inspected right away. Burning Smell While Driving A leaking transmission often leads to low fluid levels, which can cause the remaining fluid to overheat. This overheating may produce a noticeable burning smell while driving or after parking. A burnt odor is a strong indication that the transmission is not being properly lubricated and needs immediate attention to prevent internal damage. Delayed/Rough Gear Shifting Transmission fluid helps create the hydraulic pressure needed for smooth gear changes. When fluid levels drop due to a leak, you may experience delayed engagement when shifting into drive or reverse, as well as hard or jerky shifts while driving. These symptoms suggest the transmission is struggling to operate correctly. Slipping Gears/Loss of Acceleration If your vehicle unexpectedly slips out of gear or struggles to accelerate, a transmission fluid leak may be to blame. Low fluid levels can cause inconsistent pressure, leading to gear slippage and reduced power delivery. This issue can be dangerous, especially when merging or driving at highway speeds.

Few things are more frustrating than seeing the check engine light turn on while you’re driving. It’s a warning that something isn’t right under the hood, but the cause can range from a minor issue to a major problem that requires immediate attention. Because modern vehicles rely heavily on sensors and computerized systems, the light can turn on for a variety of reasons. At A-1 Automotive, our local mechanics provide expert check engine light diagnostics and repair in the greater Portland, OR area. Here’s a look at four issues that commonly cause the check engine light to illuminate. Faulty Oxygen Sensor The oxygen sensor monitors how much unburned oxygen is in the exhaust and helps regulate the engine’s air–fuel mixture. When it starts to fail, fuel-efficiency drops and emissions increase. Left unaddressed, it can even damage the catalytic converter. Replacing it early helps your vehicle run more efficiently and prevents bigger repair costs. Failing Ignition Coils or Spark Plugs Ignition coils and spark plugs play essential roles in powering your engine. When either one fails, the engine may misfire, run rough, or lose power. Misfires are a major trigger for the check engine light because they contribute to poor engine performance. Replacing faulty coils or plugs can restore smooth performance. Catalytic Converter Problems Your catalytic converter helps reduce harmful exhaust emissions, but when it becomes clogged or begins to fail, it can cause major significant issues. A failing converter often leads to reduced power, poor fuel-economy, and a persistent check engine light. Because of the catalytic converter’s important role, issues with it need to be addressed ASAP. Mass Airflow Sensor Issues The mass airflow sensor measures how much air enters the engine so the computer can inject the right amount of fuel. When it malfunctions, the engine may hesitate, stall, or idle poorly. A bad MAF sensor is a frequent cause of check engine warnings.

Winter in Portland, OR, often brings a mix of rain, cold temperatures, and occasional icy conditions that can put your car to the test. Preparing your vehicle before the weather turns harsh can help you stay safe and avoid breakdowns. From ensuring your brakes are ready to stop on slick roads to keeping your visibility clear, a little preparation goes a long way. At A-1 Automotive, we provide expert winter auto maintenance in the greater Portland, OR area. Here are five tips for getting your car ready for the Pacific Northwest winter. Have Your Brakes Inspected Wet and slippery roads are common in Portland’s winter months, making reliable brakes an absolute must. If your brake pads are worn or your rotors are uneven, your stopping distance can increase in slick conditions. A professional brake inspection will ensure that your pads, rotors, and brake fluid are all in good shape. Addressing any issues early will give you the peace of mind that your brakes will respond properly when you need them most. Get Your Battery Tested Cold weather can be tough on car batteries. Low temperatures can decrease their ability to hold a charge. If your battery is more than three years old or you’ve noticed slow cranking recently, it’s smart to have it tested before winter hits. A technician can check the voltage and overall health of your battery to make sure it’s strong enough to start your car on chilly mornings. Replace Worn Wiper Blades Constant rain is a fact of life in Portland winters, so clear visibility is crucial. Wiper blades wear out over time, leaving streaks or skipping across the glass. If you notice uneven wiping, replace them right away. Installing high-quality, all-season or winter wiper blades ensures that rain and slush are cleared efficiently, keeping your windshield clear in wintry conditions. Use Winter-Grade Wiper Fluid Standard wiper fluid can freeze when temperatures drop, leaving you unable to clear your windshield. Switching to a winter-grade wiper fluid designed to resist freezing ensures that your washer system continues to function even on frigid mornings. Check Your Heater and Defroster Before winter begins, it’s important to make sure your heater and defroster are working properly. A functioning heater keeps you warm, while a reliable defroster prevents fogged or frosted windows that can block your view. If you notice weak airflow or fog that doesn’t clear quickly, have your system inspected to ensure it’s ready for the cold, damp Portland weather.
