What Causes Low Transmission Fluid Level in Teana?
2 Answers
Reasons for low transmission fluid level in Teana: Oil leakage due to aging of transmission housing seals. Oil leakage caused by deteriorated transmission oil seals. Oil leakage resulting from cracked transmission housing. Hazards of low transmission fluid level: If the automatic transmission fluid level is too low, abnormal noises in the automatic transmission are likely to occur. This happens because when the fluid level is low, air can easily enter and circulate within the oil pump, mixing with the fluid and causing decomposition, which leads to noise. Low fluid levels also increase the risk of clutch and brake slippage, and may even cause complete failure of the automatic transmission. 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 numerous air bubbles that result in slippage.
I also encountered a transmission fluid warning when I used to drive a Teana. The most common issue is oil leakage, so it's crucial to get under the car and check for oil stains around the transmission pan, axle shaft seals, and cooler line connections. Especially for older cars, the rubber seals can age and crack, leading to sneaky oil seepage. Last time, my car had a cracked transmission pan gasket, leaking about half a bottle per month, leaving a small shiny oil puddle in the garage parking spot. Additionally, if the mechanic didn't tighten the drain plug properly during an oil change or if the filler cap wasn't secured, oil could slowly leak out after long bumpy trips. Here's a small tip: don't panic if the fluid level shows low right after a cold start. Drive for about ten minutes to warm up the transmission, then recheck—the fluid level is accurate only when the oil is warm.
