Symptoms - Automatic Transmission Shift Lock Control: Notes
IMPORTANT:
Review the system operation in order to familiarize yourself with the system functions. Refer to Automatic Transmission Shift Lock Control Description and Operation .
IMPORTANT:
For Envoy, Trailblazer, Rainer, and Saab applications depress the button on the side of the shift lock actuator. With the button depressed, cycle the plastic straw within the shift lever 3 to 5 times. The straw should move smoothly and freely except near the top of the travel where additional force will be required to mechanically actuate the park lock mechanism inside of the shift lock actuator. If there is stick/slip or abnormal friction while cycling the plastic straw or if the straw is altogether stuck in the lever, the entire control assembly (shifter and shift lock actuator) needs to be replaced.
