Known issues for this car

Before you buy this car

From the gearbox guide

1. Check the overheating history (needs a scanner). Read stored over-temperature events and the oil temperature after a long drive. Repeated limp mode or a burnt oil smell means a rebuild risk.
2. Test the torque converter. At a steady light throttle, feel for a shudder or stutter in one speed window. That points to the lock-up clutch inside the converter.
3. Read the valve body codes (needs a scanner). Check solenoid codes and hot pressure. Stored solenoid or pressure codes point to valve body wear.
4. Road test in slow city traffic. Spend at least 15 minutes in town and provoke a 2-3 upshift. A hard shunt, a flare or a delayed take-up points to worn parts or old fluid. Scan for codes afterwards.
5. Ask for the oil history. No fluid change by 100,000 km is the common version of the shift complaint. Invoices for a flush and filter count.
