Occasionally my traction off light comes on, but there is no change in how the transmission performs it shifts and runs like a new car.

Traction off light on

Good morning.
Do you have a scan tool to access the ABS system to check for any stored codes? It is part of the ABS system.
I see you are listed as a mechanic. Is the ABS light coming on as well?

LOW TRACTION
The IPC illuminates the low traction indicator when the following occurs:
^ The Electronic Brake Control Module (EBCM) detects a traction control event. The IPC receives a class 2 message from the EBCM requesting illumination.
^ The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
TRACTION OFF
The IPC illuminates the traction off indicator when the following occurs:
^ The electronic brake control module (EBCM) inhibits the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The traction control system is disabled when the following occurs:
- (Chevrolet Only) The shift lever is in FIRST (1) or SECOND (2) gear. The EBCM receives a class 2 message from the powertrain control module (PCM) indicating the gear position.
- (Pontiac and Oldsmobile Only) The Body Control Module (BCM) detects that the traction control switch is pressed (signal circuit is low). The EBCM receives a class 2 message from the BCM indicating the switch status.
- The BCM detects that the park brake is engaged (signal circuit is low) and that the engine is on. The EBCM receives a class 2 message from the BCM indicating the park brake status.
- The PCM detects certain malfunctions and is unable to perform torque reduction requests from the EBCM. The EBCM receives a class 2 message from the PCM indicating that traction control cannot be performed.
^ The EBCM detects a malfunction in the traction control system. The IPC receives class 2 messages from the EBCM requesting illumination of both the service vehicle soon and traction off indicators.
^ The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately three seconds.
