FREQUENTLY ASKED QUESTIONS
What does a flashing check engine light mean? A flashing check engine light indicates an active, serious problem — most commonly an engine misfire that can damage your catalytic converter if left unaddressed. A solid check engine light is less urgent but still needs attention. Either way, bring your vehicle in as soon as possible so we can diagnose the issue accurately.
​
Can you clear the check engine light without fixing the problem? We can clear fault codes, but if the underlying issue isn't repaired the light will return. At Transmission Corp of America, we diagnose the root cause first and give you a clear explanation of what needs to be fixed before we do any work — no unnecessary repairs.
