Vehicle Is Disabled

WARNING: This page is about a different variant/trim than selected.
  1. Check for transmission fault codes using the appropriate scan tool.
  2. Check for cracked, leaking transmission cooler lines.
  3. Check transmission fluid level and condition.
  4. With the transmission in the Park position, attempt to rotate drive shaft(s) to ensure transmission output shaft coupler/flange is secure.
  5. Check the transfer case operation (if equipped).
  6. Raise and support the vehicle, start the engine with the transmission in the Park position and allow the vehicle to idle for several minutes, shift the transmission into gear, and note following:
    1. If propeller shaft turns but wheels do not, problem is with differential or axle shafts.
    2. If propeller shaft does not turn and transmission is noisy, stop engine. Remove oil pan, and check for debris. If pan is clear, remove transmission and check for damaged driveplate, torque converter, transmission oil pump, or input shaft.
  7. Check the Transmission Control Module Assembly (TCMA), wiring, valve body, and solenoids (utilize fault codes to diagnose if available).
