Severity: Serious Can you drive? With caution: limp mode possible, have it checked soon Make: All makes (OBD-II standard)

Typical symptoms

Much higher motorway consumption
Engine revs not dropping in fifth or sixth
Transmission oil running hot
Vibration at steady speed

Common causes

Worn-out transmission fluid or wrong specification
Faulty lock-up control solenoid
Worn converter clutch
Transmission control unit not commanding lock-up
Clogged transmission filter

What to do

Start with an oil and filter change using exactly the specified fluid: on many automatics this genuinely fixes it, because degraded fluid cannot hold lock-up pressure. If the code returns after the service, the converter is worn and needs replacing.
