What causes low transmission fluid level in the Teana?
2 Answers
Reasons for low transmission fluid level in the Teana: Oil leakage caused by aging sealing rings of the transmission housing. Oil leakage due to deteriorated transmission oil seals. Oil leakage resulting from cracks in the transmission housing. Hazards of low transmission fluid level: If the automatic transmission fluid level is too low, abnormal noises in the transmission are likely to occur. This happens because when the fluid level is low, air can easily enter the oil pump's internal circulation, mixing with the fluid and causing it to break down, leading to noise. A low fluid level also increases the risk of clutch and brake slippage, and may even result in complete transmission failure. Hazards of high transmission fluid level: If the automatic transmission fluid level is too high, slippage can also occur. This is because when the transmission operates with excessive fluid, the planetary gear sets vigorously agitate the fluid, generating a large amount of air bubbles, which leads to slippage.
Last time when I had my car repaired, I encountered the issue of low transmission fluid level in the Teana. Common causes include oil leakage, such as aging of the oil pan gasket or loose oil pipe connections leading to fluid seepage. It could also be due to normal consumption, as the fluid gradually decreases over time, especially with aggressive driving or high-temperature environments accelerating fluid loss. Another possibility is insufficient fluid added during the last maintenance, requiring a recheck. If low fluid level is left unaddressed, the internal gears of the transmission may overheat and get damaged, increasing the risk of gear shifting hesitation or unusual noises while driving. I recommend first confirming the fluid level using the dipstick; the Teana's dipstick check point is conveniently located near the engine for easy operation. If the fluid level is low, promptly add the appropriate transmission fluid—preferably at an authorized service center using OEM fluid to avoid compatibility issues—saving small costs now may prevent big expenses later. If doing it yourself, be careful not to overfill or introduce contaminants, ensuring the surrounding area is clean. Regular checks every six months can help prevent this issue from occurring.
