Your vehicle’s transmission relies on fluid to function properly, providing the necessary lubrication, cooling, and hydraulic pressure to keep gears shifting smoothly. When transmission fluid begins to leak, it can quickly lead to serious problems. Recognizing the warning signs early and visiting an auto repair shop promptly can help prevent transmission failure. At American Five Star Auto Repair & Transmission, we provide expert transmission leak repair in the greater Tempe, AZ area. Here are four signs of a transmission fluid leak that should never be ignored. Red Puddles Under the Vehicle One of the most telltale signs of a transmission fluid leak is the appearance of reddish fluid under your car. Transmission fluid has a distinct color that helps set it apart from other automotive fluids. If you notice puddles or stains where your car is parked, it’s time to get your car checked by a professional. Even small leaks can worsen quickly and lead to expensive damage. Slipping or Hesitation During Gear Shifts If your vehicle hesitates or slips when shifting gears, low transmission fluid levels from a leak could be the culprit. Transmission fluid enables smooth gear transitions, and when the system is low on fluid, it may struggle to engage gears properly. You might notice a delay when shifting from park to drive or an unexpected increase in engine RPMs without a corresponding change in speed. These symptoms indicate a serious issue that should be addressed immediately. Unusual Noises While Driving A transmission that is low on fluid may produce whining, clunking, or grinding noises. These sounds often occur during gear changes or while accelerating. Because transmission components rely on fluid to reduce friction and wear, a leak can lead to increased contact between metal parts, resulting in concerning noises. Ignoring these sounds can lead to further internal damage and much higher repair bills. Burning Smell From Under the Hood Transmission fluid helps regulate the temperature of the system. When fluid levels drop due to a leak, the transmission may overheat. This can cause the remaining fluid to burn, producing a strong, acrid odor. A burning smell coming from under the hood is a serious red flag and often points to overheating or fluid leakage. Continuing to drive under these conditions can cause major damage.
