* Internal Leaks: Leaks can occur *inside* the transaxle, leading to fluid loss without any external evidence. This can cause serious transmission damage.
* Low Fluid Level: Even without a leak, the fluid level could be low due to a previous leak that's since stopped, or from normal fluid degradation and loss over time. Low fluid level can severely damage the transmission.
* Fluid Condition: The fluid itself might be degraded and contaminated, even if the level seems okay. Old fluid loses its lubricating and cooling properties, leading to premature wear.
What you should do:
1. Check the Transmission Fluid Level: This is crucial. Consult your owner's manual for the correct procedure. The level should be checked with the engine running and the transmission at operating temperature. Low fluid is a significant problem.
2. Inspect the Transaxle for Leaks: Carefully examine the transaxle for any signs of fluid, paying close attention to seals, gaskets, and the pan.
3. Check the Fluid Condition: If you can access the fluid (through the dipstick), check its color and smell. Fresh fluid should be red or pink and have a relatively mild odor. Dark brown or burnt fluid indicates significant degradation and needs to be changed immediately. A burning smell is a serious warning sign.
4. Consider a Professional Inspection: If you're unsure about any of these steps, or if you find any issues, it's best to have a qualified mechanic inspect the transaxle. Ignoring potential problems can lead to costly repairs down the line. A professional can also diagnose internal issues that you can't see from the outside.
In short, while the absence of visible leaks is positive, it doesn't guarantee a healthy transaxle. Regular fluid checks and maintenance are essential to prevent costly repairs.
