1. Overfilling the transmission: If the transmission is overfilled, it can cause pressure to build up and force oil out the vent. Check the transmission oil level and make sure it is at the correct level.
2. Damaged or worn transmission components: If the transmission components are damaged or worn, it can cause excessive play and allow oil to leak out the vent. Common culprits include worn gears, bearings, and seals.
3. Faulty transmission vent: The transmission vent may be clogged or damaged, preventing it from properly releasing pressure. Check the vent and make sure it is clear and unobstructed.
4. Damaged transmission case: If the transmission case is cracked or damaged, it can allow oil to leak out. Inspect the transmission case for any cracks or damage.
If you are not comfortable inspecting or repairing the transmission yourself, it is best to take it to a qualified mechanic for diagnosis and repair.
