P0741 — Torque Converter Clutch Performance / Stuck Off

CAUTIONIs it safe to drive? The torque converter clutch isn't locking up when commanded. Economy suffers; the trans runs hotter than designed at highway speed.

What P0741 means

The PCM commanded TCC lockup but the input-vs-output speed difference stayed too high — the clutch didn't engage. This is the mechanical/performance version of TCC failure. Check fluid and solenoid before assuming internal damage.

Most likely causes (in order)

  1. Worn internal TCC friction lining
  2. Faulty or stuck TCC solenoid
  3. Low hydraulic pressure (low fluid, worn pump)
  4. Low or degraded transmission fluid
  5. Valve body issue

Symptoms you might notice

What to check first

Compare input vs. output speed at highway cruise with a scanner — excessive slip (>50 RPM steady) while TCC is commanded on points to the TCC friction material or hydraulic pressure. Change the fluid first.
