### Removal Procedure

1. Remove vehicle components only if necessary, in order to provide adequate clearance for transmission removal.
2. The vehicle will be equipped with one of the following:

• | Apron-type flywheel housing (2)

• | SAE number 2 type flywheel housing (6)

- | The apron-type flywheel housing (2) has a sheet metal pan which covers the lower portion of the clutch and flywheel. The flywheel housing is attached separately from the transmission body.
