Installation
Installation is in the reverse order of removal.
CAUTION:
• Completely remove all moisture, oil and old gasket from the oil pan gasket mounting surface of tran-
saxle case and oil pan.
• Do not reuse O-rings, lip seals, oil pan gasket and oil pan bolts.
• Apply ATF to manual valve, O-rings, li p seals and sliding surfaces of the transaxle case.
NOTE:
• Set manual shaft in “N” position, then align manual plate (1) with
groove in manual valve (2).
• After installing control valve assembly to transaxle case, make sure that selector lever can be moved to all positions.
• After completing installation, check for A/T fluid leakage and A/T fluid level. Refer to AT-17, " Checking A/T Fluid " .
