TCC Stator Temperature Circuit Range/Performance

on 2002 Ram 1500 5.7L V8 · 4WD

What this code means

The transmission control module detects an out-of-range signal from the torque converter clutch stator temperature circuit. This can affect converter lockup timing and transmission cooling protection.

  • Transmission overheating warning
  • Reduced fuel economy

Common causes

  • Faulty stator temperature sensor
  • Damaged sensor wiring or connector
  • Low or contaminated transmission fluid
  • Faulty transmission control module

Diagnostic steps

  1. Scan for related transmission codes
  2. Check transmission fluid level and condition
  3. Inspect sensor wiring and connectors
  4. Test sensor resistance against specification

⚠ STILL BEHIND THE PAYWALL
The 2002 Ram 1500 repair data is incomplete because no one has sponsored it yet. For $99, we generate the full step-by-step procedures, then fact-check them with a second AI pass and your expert review. Your name on every procedure, permanently.
The same data would cost $169/mo from Mitchell1 or $30/year from ALLDATAdiy — and you'd be renting access, not freeing it. Sponsor once, free forever.
