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?

Faulty seals axle, output shaft, o r input shaft seals.

Loose o r improperly torqued drain plugs.

Worn o r damaged pan gaskets.

These issues often occur due to vibration, poor-quality materials, o r rough roads wearing out the sealing components over time.

⛔ Conclusion: Leaks are a common problem in Pakistan and usually stem from aging gaskets, poor seal quality, o r loose fittings.
