Is the Oil Seepage at the Bottom of the Transmission a Serious Problem?
1 Answers
Oil seepage at the bottom of the transmission needs to be analyzed based on specific circumstances. Here are the relevant details: Minor seepage: If there are slight oil traces that do not drip onto the ground, it is considered minor seepage, not a leak. It can be temporarily ignored and addressed during the next maintenance visit or when convenient at a 4S shop. The inspection method involves wiping the bottom of the transmission clean; if oil stains reappear the same day, it indicates a leak, not just seepage. Oil leak: The primary cause of this issue is the aging of sealing components. Vehicles are inherently consumable products, and prolonged use can cause seals to harden and age, losing their plasticity. Consequently, under the high-intensity working conditions of the transmission, the seals begin to shrink, harden, and eventually fail, leading to transmission oil leaks.
