Reasons why an automatic transmission may squeeze out oil:
1. Overflow of transmission fluid (ATF)
* If the automatic transmission is overfilled, excess pressure can squeeze ATF out of the breathers or other leak points.
2. Defective seals or gaskets
* Worn or damaged seals or gaskets can leak ATF, causing leaks and low fluid levels.
3. Problems with the oil pump
* A faulty oil pump can create excessive pressure, which pushes ATF out of the automatic transmission.
4. Clogged automatic transmission filter
* A clogged filter reduces ATF flow, which can cause excessive pressure and oil squeezing out.
5. Turbine pump malfunction
* A worn or damaged turbine pump can create excessive ATF pressure, causing leaks.
6. Pressure control valve malfunction
* A faulty pressure control valve may not regulate ATF pressure properly, resulting in excessive pressure and leaks.
7. Mechanical damage
* Cracks, breaks or other mechanical damage in the automatic transmission housing can create leak points for ATF.
8. Wear of gears and bearings
* Excessive wear on gears and bearings can create a gap through which ATF can leak.
9. Improper maintenance
*Failure to replace the ATF and filter at the proper time can result in sludge buildup and clogging, leading to pressure problems and leaks.
10. Using the wrong ATF
*Using the wrong ATF can cause viscosity or temperature problems, which can negatively affect ATF pressure and cause leaks.
