Verify that the selector lever can only be shifted as shown in the figure. When shifting from P range, do so with the ignition switch ON and the brake pedal de- pressed. 2. Verify there is a click at each range when shifted from P -+ L range. 3. Verify that the positions of the selector lever and the indi- cator are aligned. 4. Verify that the button returns smoothly when pushed to shift. Adjustment Lever position 1. Disconnect the negative battery cable to deactivate the shift-lock. 2. Remove the rear console, selector knob, selector sleeve, and indicator panel. (Refer to "Shift-lock actuator inspection"; page K-159, steps 1-45.) 3. Loosen the locknut. 4. Shift the transmission to P range by pushing the adjust- ment lever forward. 5. Adjust the lever so that the clearance between the guide plate and the guide pin in P range with the push rod light- ly depressed is as shown. 6. Tighten the locknut. Tightening torque: 18-24 Nem (1.8-2.5 kgf-m, 14--18 ft-lbf) 7. Move the selector lever to N and D ranges and verify that there is the same clearance between the guide plate and the guide pin. 8. If not as specified, readjust the lever. 9. lnstall the indicator panel, selector sleeve, selector knob, and rear console in the reverse order of removal. 10. Check the selector lever operation. (Refer to "lnspec- tion"; page K-161.) Indicator panel 1. Remove the rear console. 2. Shift the selector lever to P range. 3. Loosen the indicator screws. 4. Align the alignment hole in the slider with the hole in the indictor panel. Install suitable heavy-gauge wire to hold the slider. 5. Tighten the indicator mounting screws in the order shown in the figure. 6. Remove the wire from the slider. 7. Verify that the selector lever properly aligns with the indi- cator in each range. 8. Verify correct operation of the emergency override but- ton. Gartner Banana
