Automatic Transmission/Transaxle: Adjustments
TRANSAXLE RANGE SWITCH ADJUSTMENT1. Place selector lever in "N" (Neutral) position.
2. Loosen the manual control lever lock nut to separate the cable and lever.
3. Place the manual control lever in the "N" (Neutral) position.
4. Turn the transaxle range switch body until the 12 mm (0.47 inch) wide end of the manual control lever aligns with the switch body flange [12 mm (0.472 inch) wide portion].
5. Tighten the attaching bolts (2 pieces) to the specified torque. Transaxle Range Switch
Attaching Bolt: 10 - 12 Nm (100 - 120 kg.cm, 7 - 9 ft. lbs.)
NOTE: When setting up the switch body, be careful O-ring not to drop from the switch body. Tighten the attaching bolts carefully.
6. Make sure that the selector lever is in the "N" (Neutral) position.
7. Adjust the flange nut so that there is no slack in the control cable and make sure that the selector lever operates smoothly.
8. Run the vehicle and confirm that the transaxle is set in each range when the selector lever is shifted to each position.
KICKDOWN SERVO ADJUSTMENT
1. Completely remove all dirt and other contaminating materials adhered around the kickdown adjust screw.
2. Loosen the lock nut.
3. Loosen and tighten the adjust screw two times by torque of 5 Nm (3.6 ft. lbs.).
4. Tighten adjust screw by torque of 5 Nm and then, loosen the adjust screw 3 to 3-1/3 turns.
5. Tighten the lock nut to the specified torque.
Lock nut: 15 - 22 Nm (150 - 220 kg.cm, 11 - 16 ft. lbs.)
NOTE: Before assembling, apply sealant (DC780) to center portion of the adjust screw.
LINE PRESSURE ADJUSTMENT
1. Drain out the automatic transaxle fluid.
2. Remove the oil pan.
3. Remove the oil filter.
4. Remove the oil-temperature sensor.
5. Press the tab of the solenoid valve harness grommet and push in.
6. Remove the valve body assembly. The manual valve can come out, so be careful not to drop it.
7. Turn the adjustment screw of the regulator valve and adjust so that the line pressure (kickdown brake pressure) reaches the standard value. When the adjustment screw is turned clockwise, the line pressure becomes lower; when it is turned counter-clockwise, it becomes higher.
Standard value: 860 - 900 kPa (122 - 129 psi, 8.77 - 9.18 kg/CM2)
Oil pressure change for each turn of adjustment screw: 38 kPa (5.4 psi, 0.39 kg/cM2)
8. Check to be sure that the O-ring is installed on the upper surface of the valve body at the place shown in the figure.
9. Replace the O-ring of the solenoid valve connector with a new one.
10. Install the valve body assembly to the case and then insert the solenoid valve connector into the case. Be sure, at this time, that the notched part of the connector faces as shown in the figure. Also be careful that the lead wiring isn't caught.
11. Tighten the valve body assembly mounting bolts to 10 - 12 Nm (100 - 120 kg.cm, 7 - 9 ft. lbs.).
12. Install the oil filter.
13. Install a new oil pan gasket with the oil pan.
14. Pour in the specified amount of Automatic transaxle fluid.
15. Make the oil pressure test. Readjust if necessary.
REDUCING PRESSURE ADJUSTMENT
If the Scan Tool is not available
1. Remove parts up to the oil filter in the same way as for adjustment of the line pressure. The valve body need not be removed.
2. Turn the adjustment screw of the lower valve body and adjust so that the reducing pressure is the standard value. When the adjustment screw is turned to the clockwise, the reducing pressure becomes lower; when it is turned to the counter clockwise, it becomes higher.
NOTE: When adjusting the reducing pressure, aim for the center value (425 kPa, 60 psi) of the standard value allowance.
Standard value 420 kPa (60 psi, 4.2 ± 0.2 kg/cM2)
Oil pressure change for each turn of the adjustment screw: 22 kPa (4.3 psi, 0.22 kg.CM2)
3. Install the oil filter and oil pan in the same way as for adjustment of the line pressure.
4. Make the oil pressure test. Readjust if necessary.
If the Scan Tool is used
5. Adjust the PC solenoid so that the kickdown brake pressure is the standard value when activated to 50% duty by the Scan Tool.
Standard value: 320±30 kPa (390 psi, 3.2±0.3 kg/cM2)
Oil pressure change for each turn of the adjustment screw: 30 kPa (3 psi, 0.3 kg/cM2)
6. Check to be sure that the reducing pressure (after the adjustment is completed) is within the range of 370 - 490 kPa (53 - 70 psi, 3.8 - 5.0 kg/cM2)
CAUTION: This adjustment should be made at an oil temperature of 80 - 90°C (176 - 194°F). If the adjustment Is made at a temperature that Is too high, the line pressure will drop during Idling, with the result that It might not be possible to make the correct adjustment.
