  Q: How to service and repair the park/neutral safety switch on Toyota Solara?

  A:

  A proper repair of the park/neutral position switch requires starting with removal of the battery and successive removal of the engine cover No. 1 sub-assembly, air cleaner assembly and air cleaner hose No. 1 and intake air resonator sub-assembly and engine under cover LH. The floor Shift Cable transmission control shift can be detached through these steps: Unconnect the park/neutral position switch connector then remove the control shaft lever nut and disconnect the control cable from the lever and remove its bracket clip. First disconnect the park/neutral position switch assembly by removing its bolts and then successively take off the lock plate, lock nut and control shaft lever. The switch must be pulled out after you remove the washers and nut and pry up the lock plate. In this step check the park/neutral position switch assembly which requires you to apply the parking brake, turn on the Ignition Switch to ON position, press the brake pedal deeply and confirm engine start-up functions properly in N or P mode but Back Up light and reverse warning buzzer activates only in R position; perform continuity test when a failure occurs. Implement the adjustment of the park/neutral position switch assembly through the following steps: loosen the 2 bolts, position the shift lever to N, align the groove with the neutral basic line while holding the switch in position before tightening the bolts to 5.4 Nm (55 kgf-cm, 48 inch lbs.) and complete the inspection. Place all installation materials first then attach the park/neutral position switch on the manual valve shaft and set the 2 bolts before putting in a new lock plate and tightening the nut to 6.9 Nm (70 kgf-cm, 61 inch lbs). The installation procedure requires the control shaft lever to be placed temporarily before turning it counterclockwise until it stops and continuing clockwise to the second notch. After removing the lever the operator must replace it with the groove aligned to the neutral basic line while tightening the two bolts to 5.4 Nm (55 kgf-cm, 48 inch lbs.) before using a screwdriver to stake the nut in position with the lock plate. The final stage involves adding the washer and nut with 13 Nm (130 kgf-cm, 9 ft. lbs.) torque. The next step involves connecting the park/neutral position switch cable before connecting the floor shift cable transmission control shift through leveraging the control cable to the control shaft lever with the nut fastened at 15 Nm (153 kgf-cm, 11 ft. lbs.) tension followed by installing a new clip on the bracket. The last installation step involves putting back the engine under cover LH and intake air resonator sub-assembly and air cleaner hose No. 1 and air cleaner assembly and engine cover No. 1 sub-assembly and battery with followup checks on the shift lever position and park/neutral position switch assembly and an initialization procedure.

  Q: How to replace the Park/Neutral Safety Switch Assy (ATM) on Toyota Solara?

  A:

  The replacement of the park/neutral position switch assy (ATM) begins with removal of essential components such as battery followed by engine cover sub-assy No.1, air cleaner assy, air cleaner hose No.1, intake air resonator sub-assy, and finally engine under cover LH. Disconnection of the floor Shift Cable transmission control shift happens by removing the nut from the control shaft lever, disconnecting the control cable from the control shaft lever and park/neutral position switch connector and by removing the clip from the control cable bracket. Begin the park/neutral position switch assy removal procedure by uninstalling the nut, washer and control shaft lever. Then pry up the lock plate, remove the lock nut and lock plate before pulling out the switch when all 2 bolts are removed. When installing the new park/neutral position switch assy begin by connecting it to the manual valve shaft then fasten the 2 bolts even if just temporary before placing a new lock plate and tightening the nut to reach 6.9 Nm (70 kgf-cm, 61 inch lbs.). The temporary installation of the control shaft lever should begin with a counterclockwise rotation until it reaches its stopping point followed by clockwise movement of 2 notches before the lever removal. Place the switch into position so its groove matches the neutral basic line while securing the 2 bolts to 5.4 Nm (55 kgf-cm, 48 inch lbs.). Install the control shaft lever after placing the washer on top followed by the nut and attain a torque reading of 13 Nm (130 kgf-cm, 9 ft. lbs.). Connect the park/neutral position switch connector followed by attaching the control cable to the control shaft lever along with the necessary nut that should be tightened to achieve 15 Nm (153 kgf-cm, 11 ft. lbs.) torque. The control cable also needs a new clip to attach to the bracket. Engine under cover LH and intake air resonator sub-assy replacement must be combined with the installation of air cleaner hose No.1 and air cleaner assy and engine cover sub-assy No.1 and battery before completing the process by adjusting shift lever position and inspecting the park/neutral position switch assy along with initialization steps.
