Subject: | Hiss/Chirp Noise in Park or Neutral (Install New Transmission Control Module (TCM) Calibration) |
Models: | 2003-2004 VUE Vehicles |
2003-2004 ION Vehicles |
with VT25E (VTi) Transaxle (RPOs M75, M16) |
Attention: | Technician |
Some customers may comment on a hissing or chirping noise. This condition occurs at normal operating temperature when the transaxle is in Park or Neutral position, and the engine RPM is at idle. The noise is similar to an alternator belt chirp or a vacuum leak.
The noise may be caused by transaxle fluid passing through a sharp-edged orifice in the control valve body spacer (with gasket) plate assembly. When the transaxle is in Park or Neutral position, line pressure fluctuates in order to clean the solenoids. This line pressure fluctuation contributes to the noise condition.
Install a new TCM calibration. The calibration lowers the line pressure used during the solenoid cleaning process.
Reprogram the TCM with the updated calibration established from the service matrix in this bulletin. Use Saturn Service Stall (SSS) software release TIS 11/2003 or higher data CD.
TCM Calibration Reprogram Procedure:
Install one of the following TCM calibrations based on the application:
