Possible causes of oil leakage from an automatic transmission:
*Pan Gasket: This gasket can wear or tear over time, causing oil to leak.
*Drain plug: The plug may be loose or damaged, allowing oil to leak.
* Oil Filter: The filter can become clogged and interfere with oil circulation, causing excessive pressure and leaks.
*Shaft Seals: The seals located on the transmission input and output shafts can wear or fail, causing leaks.
* Bearings: Faulty or worn bearings can create excessive heat and damage seals, leading to leaks.
* Depressurization of the transmission case: As a result of impacts, corrosion or damage, cracks or holes may form in the transmission case through which oil leaks.
* Insufficient oil level: If the gearbox oil level is too low, it may cause leaks.
Steps to fix an automatic transmission oil leak:
1. Determine the source of the leak: Inspect the transmission and oil pan for leaks.
2. Check oil level: Check the gearbox oil level and add oil if necessary.
3. Replace the oil pan gasket: Remove the oil pan and replace the gasket. Torque the drain plug bolts to specifications.
4. Replace the oil filter: Replace the oil filter with a new one.
5. Replace the shaft seals: If the shaft seals are leaking, they will need to be replaced.
6. Troubleshoot bearings: Replace faulty or worn bearings.
7. Seal the Transmission Housing: Clean and seal any cracks or holes in the transmission housing.
8. Refill with new oil: After repairing the leak, fill the transmission with new oil.
