Disadvantages of the Peugeot AT6 gearbox
- This is a robust automatic transmission, but with vigorous driving, the torque converter lockup clutch wears out;
- Then the wear debris clogs the valve body, and the transmission immediately begins to struggle;
- All other problems are caused by overheating due to a small heat exchanger;
- High temperatures destroy the Teflon rings, and the lubrication pressure drops;
- Then the clutch packs begin to burn out, followed by the drums and other parts of the automatic transmission.
