  Q: How to install the park/neutral safety switch assembly onto the U340E automatic transaxle on Toyota Yaris?

  A:

  The U340E automatic transaxle requires installation of the park/neutral position switch assembly by first tightening manual valve shaft nut to 6.9 Nm, then replacing the lock plate and installing new hardware and bolts in their proper places before tightening bolts to 5.4 Nm. The installation starts with a temporary fitment of the control shaft lever which should be turned counterclockwise stopping at the first notch and proceeding clockwise two notches and then removing the lever. The groove needs to point at the neutral basic line before tightening the two bolts to 5.4 Nm (55 kgf-cm, 48 in-lbf). Insert the lock plate into a screwdriver and stake the nut. After that, add the control shaft lever to the nut and washer and tighten to 13 Nm (130 kgf-cm, 9 ft-lbf). The park/neutral position switch assembly requires a connection to its connector. Install the transmission control cable assembly to the control shaft lever using the provided nut followed by cable bracket installation with a new clip while tightening the nut to 12 Nm. The last step requires secure connection of the cable to the negative end of the battery using a torque of 5.4 Nm (55 kgf-cm, 48 in-lbf). Test and check the shift lever position after examining the park/neutral position switch assembly before installing the engine under cover LH.

  Q: How to remove the Neutral Safety Switch from the U340E automatic transaxle on Toyota Yaris?

  A:

  The first step to remove the Neutral Safety Switch from the U340E automatic transaxle involves disconnecting the negative battery terminal cable. The next step involves the removal of the left-hand side engine under cover. You need to disassemble the transmission control cable assembly by first taking off the nut before unconnecting the control cable from the control shaft lever. Then remove the clip to separate the control cable from the control cable bracket. To proceed, disconnect the park/neutral position switch assembly connector then remove the nut followed by the washer and control shaft lever. The lock plate requires prying to remove and the manual valve shaft nut requires removal too. First, unwrap the manual valve shaft nut and then remove the two bolts to pull out the park/neutral position switch assembly.
