  1. Set the park lever in the P position, then check that the park pawl (A) engages the park gear (B).
  1. If the park pawl does not engage fully, do the park lever stop inspection and adjustment.
  1. Tighten the lock bolt (C), and bend the lock tab of the lock washer (D) against the bolt head.
  1. Install the ATF feed pipe (A) into the idler gear shaft, and install the ATF lubrication pipe (B) into the transmission housing.
  1. Install a new gasket (A) on the transmission housing, and install the two dowel pins (B) and new O-rings (C) over the top of the ATF feed pipes.
  1. Install the end cover (D), and tighten the three special bolts (E) and the 6 x 1.0 mm bolts (F) (12 bolts).
  1. Install the clamp bracket (G) on the end cover with the bolt (H).
  1. Move the selector control shaft (A) from the P position to the N position by turning the selector control shaft with the selector control lever on the torque converter side.
    NOTE: Do not squeeze the end of the selector control shaft tips together when turning the shaft. If the selector control shaft tips are squeezed together, it will cause a faulty shift position signal or position due to the play between the selector control shaft and the transmission range switch.
  1. For R20A3 engine model: Set a transmission range switch (A) to the N position. Align the cutouts (B) on the rotary-frame with the neutral positioning cutouts (C) on the transmission range switch, then put a 2.0 mm (0.08 in.) feeler gauge (D) or feeler gauge blade in the cutouts to hold transmission range switch in the N position.
    NOTE: Be sure to use a 2.0 mm (0.08 in.) feeler gauge, feeler gauge blade, or equivalent to hold the transmission range switch in the N position.
  1. For R20A3 engine model: Install the transmission range switch (A) gently on the selector control shaft (B) while holding it in the N position with the 2.0 mm (0.08 in.) feeler gauge (C).
  1. For R20A3 engine model: Tighten the bolts on the transmission range switch while you continue to hold it in the N position. Do not move the transmission range switch when tightening the bolts. Remove the feeler gauge.
  1. For R20A3 engine model: Connect the transmission range switch connector (A) securely, then install the harness clamps (B) on the clamp bracket (C). Install the transmission range switch cover (D).
  1. For K24Z3 engine model: Set a transmission range switch (A) to the N position. Align the cutouts (B) on the rotary-frame with the neutral positioning cutouts (C) on the transmission range switch, then put a 2.0 mm (0.08 in.) feeler gauge (D) or feeler gauge blade in the cutouts to hold transmission range switch in the N position.
    NOTE: Be sure to use a 2.0 mm (0.08 in.) feeler gauge, feeler gauge blade, or equivalent to hold the transmission range switch in the N position.
