What can fail
When quick shift is used at high engine load, the engine may backfire. This can damage the air suction valves, allowing hot exhaust gas to blow back and melt nearby parts.
What the fix does
Dealers will reprogram the engine control unit, replace the air suction valves, and inspect and replace any damaged surrounding parts.
