Shift Timing Solenoid Performance

on 2000 GMC Savana 4.3L V6 · RWD

What this code means

The shift timing solenoid is not performing within expected parameters during gear changes. This affects shift quality and timing precision, comparable to generic shift solenoid performance codes like P0751.

Symptoms

  • Transmission slipping
  • Erratic shift timing

Common causes

  • Faulty shift timing solenoid
  • Low or dirty transmission fluid
  • Clogged solenoid or valve body passages
  • Damaged solenoid wiring or connector

Diagnostic steps

  1. Scan codes and review freeze frame data
  2. Check transmission fluid level and quality
  3. Test shift solenoid resistance and operation
  4. Inspect valve body and solenoid circuit wiring

⚠ STILL BEHIND THE PAYWALL
The 2000 GMC Savana 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.
