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- 1 6 , "
Checking A/T Fluid" .
