Disadvantages of the Peugeot ATN8 gearbox
- This is a reliable automatic transmission, and all its problems stem from a weak cooling system;
- The tiny heat exchanger quickly becomes clogged with dirt, and the automatic transmission begins to overheat;
- High temperatures destroy the Teflon rings, and the oil pressure drops;
- Then the clutch packs begin to burn, then the drums become damaged, and so on;
- And don’t forget to change the oil; the valve body is very sensitive to the cleanliness of the lubricant.
