After installation is completed, check continuity of PNP switch. Refer to AT- 1 6 1 , "PNP, 3RD POSITION
SWITCH AND CLOSED THROTTLE, WIDE OPEN THROTTLE POSITION SIGNAL" .
PARK/NEUTRAL POSITION (PNP) SWITCH ADJUSTMENT
1. Set select lever and manual shaft in “N” position.
2. Remove control cable from manual shaft.
3. Loosen PNP switch fixing bolts.
4. Use a pin [3 mm (0.12 in) dia.] for this adjustment.
a. Insert the pin straight into the manual shaft adjustment hole.
b. Rotate PNP switch until the pin can also be inserted straight into
the hole in PNP switch.
5. Tighten PNP switch fixing bolts to the specified torque. Refer to
AT- 2 3 0 , "
COMPONENTS" .
6. Remove pin from adjustment hole after adjusting PNP switch.
7. Check continuity of PNP switch. Refer to AT- 1 6 1 , "

3. Remove differential side oil seals using a flat-bladed screw-
driver.
CAUTION:
Be careful not to scratch transaxle case and converter
housing.
Installation
1. Drive differential side oil seals using the drift below into case
until it become flush. Refer to dimensions “A” and “B”.
Unit: mm (in)
NOTE:
Differential side oil seal pulling direction is used as the refer-
ence.
Drift to be used:
CAUTION:

Do not reuse differential side oil seals.

Apply ATF to differential side oil seals.
2. Reinstall any part removed.
CAUTION:
If lubricant leak has occurred, after finishing work, check A/T fluid level. Refer to AT- 1 4 , "
Checking
A/T Fluid" .
