Drive with caution — fix soon.
This code means the computer detected an on-and-off (intermittent) problem in the torque converter clutch circuit, which controls when the converter locks up. It's commonly caused by loose or corroded connectors, chafed wiring, or a failing solenoid that only acts up occasionally. Because it's intermittent, diagnosis focuses on the wiring and connections, and it's often fixable without major transmission work.
$150 – $900
Varies by vehicle and root cause.
Usually yes, since the fault is intermittent and mainly affects efficiency and smoothness. Still, the transmission can run hotter, so have it checked before it worsens.
Wiring or connector repairs and a solenoid replacement typically run $150 to $900. If the torque converter needs replacing, expect higher costs after a full diagnosis.
It's generally moderate. It won't leave you stranded right away, but the intermittent fault and extra heat can lead to bigger transmission issues if left unaddressed.
Intermittent faults usually come from loose or corroded connections or wiring that only breaks contact under certain conditions, which is why the symptoms and light can come and go.
