One of the most common questions drivers ask when buying a car is:

Does a manual transmission last longer than an automatic transmission?

Traditional Automatic Transmission

Uses:

• planetary gear sets

• torque converter

• hydraulic system

• multiple clutch packs

It shifts through fixed gears (1st, 2nd, 3rd, etc.).

Transmission repairs are among the most expensive automotive fixes.

Average repair costs:

• Fluid service: $150–300

• Solenoid repair: $300–800

• Torque converter: $800–2000

• Rebuild/replacement: $2500–5000+

The key is catching early warning signs.

P0740 – Torque Converter Clutch (TCC) Circuit Malfunction

This code means the transmission control module (TCM) has detected a problem with the torque converter clutch system.

P0700 – Transmission Control System Malfunction

Important:

P0700 does NOT tell you what is wrong with the transmission.

The real problem is stored as a separate transmission-specific code.

P0700 is a “flag” telling the engine computer that something is wrong in the transmission system.

Catalytic converters contain precious metals like platinum, palladium, and rhodium.

When damaged, replacement can cost:

💰 $800–1500 (aftermarket)
💰 $1500–4000+ (OEM)
💰 $3000–6000 on luxury vehicles

And many failures are caused by ignoring certain engine codes.

Here are the 5 most dangerous ones.

If your engine stalls while driving, it is not just inconvenient — it can be dangerous.

Modern vehicles rarely stall without a reason.
Often, a stored OBD2 code can explain exactly why it happened.

Here are the most common codes linked to engine stalling.

If your Check Engine Light is flashing, stop driving immediately.

A flashing light usually indicates active misfire that can damage the catalytic converter.

The list below applies to solid check engine lights only, where the car runs normally.

P0335 – Crankshaft Position Sensor “A” Circuit Malfunction

This code means the engine control module (ECM) is not receiving a proper signal from the crankshaft position sensor (CKP).

The crankshaft sensor is one of the most important sensors in the engine.

P0456 – EVAP System Very Small Leak Detected

This code means the vehicle’s evaporative emission control system (EVAP) has detected a very small leak.

The EVAP system prevents fuel vapors from escaping into the atmosphere.

A “very small leak” can be as small as 0.020 inches — almost invisible.
