• Q: How to replace the PARK/NEUTRAL SAFETY SWITCH ASSY (ATM) on 2003 Toyota Corolla?

  A: You should start the PARK/NEUTRAL POSITION SWITCH ASSY (ATM) replacement by removing first the battery and its carrier using the 4 bolts. The next step involves disconnecting the floor shift cable transmission control shift by removing the nut from the control shaft lever to separate the control cable from its lever attachment which allows removal of the clip that connects the cable to the bracket. Next disconnect the park/neutral position switch assembly connector then remove the nut and washer and control shaft lever before prying out the lock plate and lastly remove the manual valve shaft nut followed by taking out the 2 installation bolts to extract the switch. You should mount the new park/neutral position switch onto the manual valve shaft and install the two bolts only temporarily before securing the device with a new lock plate and nut tightened to 5.5 Nm (56 kgf-cm, 49 inch lbs.). The control shaft lever requires temporary installation before clockwise movement of 2 notches until reaching stops. After lever removal align the groove with the neutral basic line while holding the switch position then tighten the bolts to 5.5 Nm (56 kgf-cm, 49 inch lbs.). Use a screwdriver to stake the nut with the lock plate before installing the control shaft lever along with the washer and nut at 12.5 Nm (127 kgf-cm, 9 ft. lbs.) torque while connecting the park/neutral position switch connector. Begin by attaching the control cable through the control shaft lever with a nut then mount both the control cable with its clip onto the bracket. Finish the installation by installing the 4 bolts with 13 Nm torque then normalize both the shift lever position and park/neutral position switch assembly for inspection.
