Test Description

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 5:  This step determines if the output shaft speed sensor signal is skewed by a large factor.
  2. 6:  This step determines if the input shaft speed sensor signal is skewed by a large factor.
  3. 7:  This step determines that shift solenoid 2 or the M2 shift valve is stuck if the TCC Slip Speed is near 0 RPM at idle in DRIVE (D).
