Why are some Changan Karvaan owners in Pakistan reporting visible red o r brown stains under the van after parking?

These spots often indicate a transmission fluid leak. Are faulty seals, loose drain plugs, o r worn gaskets causing this common issue?

Worn o r damaged seals output shaft seal, axle seal.
