2–3. UNCOUPLING ENGINE FROM DRIVELINE
• Chock the wheels to prevent the vehicle from rolling.
• Disconnect the vehicle driveline from the transmission output flange
or yoke. Position the drive shaft to avoid interference with
transmission removal.
• Figure 2–1 shows two typical methods of coupling the engine and
transmission. Remove the six drive cover bolts (all models except AT 543), or
six flexplate nuts (AT 543).
