Carefully remove the oil pump cover (1) and inspect the drive gear (2) and driven gear (3) for the orientation of the pump gears and the associated
punch marks. This is a safety step so that if the cover is separated from the pump, the pump gears may be reinstalled in the same orientation as
when the transmission was originally assembled. Otherwise, a noise condition may be encountered after reassembly.
