Is the Transmission Bottom Oil Seepage a Serious Problem?
1 Answers
Transmission bottom oil seepage needs to be analyzed based on specific conditions: 1. Minor seepage: Slight oil traces that do not drip onto the ground are considered minor seepage, not oil leakage. 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 transmission bottom clean; if oil stains reappear the same day, it indicates oil leakage, not seepage. 2. Oil leakage: The primary cause of this issue is the aging of sealing components. Vehicles are consumables themselves, and prolonged use can cause sealing components to harden and age, losing their original plasticity. Under the high-intensity working conditions of the transmission, the sealing components begin to shrink, harden, and eventually cannot withstand the stress, leading to fractures and resulting in transmission oil leakage.
