WARNING: This page is about a different car, the 2020 Subaru Impreza. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the transmission assembly from the vehicle. Refer to CONTINUOUSLY VARIABLE TRANSMISSION (TR580 IMPREZA)>AUTOMATIC TRANSMISSION ASSEMBLY>REMOVAL .
  2. Remove the torque converter assembly. Refer to CONTINUOUSLY VARIABLE TRANSMISSION (TR580 IMPREZA)>TORQUE CONVERTER ASSEMBLY>REMOVAL .
  3. Remove the oil pump chain, oil pump sprocket, driven sprocket and oil pump chain cover.
    NOTE: Oil pump chain cover may be hard to remove because the driven sprocket is installed to the shaft side of the oil pump. Do not remove it forcibly. Remove it while holding the driven sprocket by hand.
