What causes the input shaft seal to fail?

Heat cycling, age, and transmission fluid contamination cause the seal lip to harden and crack, leading to oil weeping onto the clutch or driveshaft.

How do I know if my input shaft seal is leaking?

Signs include oil residue around the bellhousing, clutch slip or judder on Kia/Hyundai vehicles, and a low transmission fluid level with no other obvious leak source.
