Possible causes of oil leakage from a Chevrolet Cruze automatic transmission:
1. Wear of gaskets and seals:
*Damaged or worn oil pan, valve body or oil line gaskets may leak oil.
2. Transmission seal malfunction:
* The input shaft or output shaft seal may become worn or damaged, causing oil to leak.
3. Damage to the oil pan:
* Impact or damage to the oil pan may cause cracks or deformation, resulting in oil leakage.
4. Oil cooler malfunction:
*A damaged oil cooler may leak oil into the external cooling system.
5. Oil overflow:
* Excessive oil levels can create pressure causing gasket or seal leaks.
6. Mechanical faults:
* Internal failures, such as worn clutches or faulty gears, can cause oil to leak from the seals.
7. Problems with the vacuum modulator:
* A faulty vacuum modulator can cause oil to leak from the vacuum line.
8. Damage to the transmission housing:
*Impact or damage to the transmission housing may cause cracks that may allow oil to leak.
9. Clogged breather:
* A clogged breather can cause pressure to build up in the transmission and leak oil through weak spots.
10. Defective hoses or pipes:
* Worn or damaged hoses or pipes connecting transmission components may leak oil.
Actions to be taken in the event of an oil leak:
1. Determine the location of the leak by drops of oil under the car.
2. Clean the area around the leak for better inspection.
3. Eliminate the cause of the leak as described above.
4. Replace the lost oil with an automatic transmission that meets specifications.
5. Renew the oil pan gasket if it was removed.
6. Check the oil level after repair and adjust it if necessary.
7. If the leak is extensive or the source is unclear, contact a qualified mechanic.
