Possible causes of oil leakage from an automatic transmission:
1. Worn or damaged seals:
*Shaft seals and oil seals can wear or become damaged over time, causing oil leaks.
2. Problems with the oil pan:
* The oil pan may be warped, cracked, or loose from the transmission, allowing oil to leak.
3. High fluid level:
* If the transmission fluid level is too high, it can cause increased pressure and seal leaks.
4. Oil line malfunction:
*Oil lines may be loose, damaged, or clogged, restricting oil flow and causing leaks.
5. Damage to the gearbox housing:
* Cracks or holes in the transmission housing may allow oil to leak.
6. Torque converter wear:
* Worn seals in the torque converter can lead to oil leaks.
7. Low fluid level:
*If the transmission fluid level is too low, it may cause seal leaks due to insufficient lubrication.
8. Overheating:
* Overheating of the transmission can lead to deformation of seals and oil leaks.
9. Heavy wear or damage:
* Severe wear or damage to internal transmission components such as gears or bearings can result in damaged housings and oil leaks.
10. Incorrect installation:
* Incorrect installation or use of unsuitable parts during transmission repair may result in oil leaks.
