Mechanical Operation
The transmission fluid in the sump area at the bottom of the transmission case flows through a transmission fluid filter to the pump assembly. The pump assembly is bolted to the converter housing and driven by a chain and sprockets. The drive sprocket is turned by the torque converter, the drive chain then transfers the torque from the drive sprocket to the driven sprocket. The driven sprocket is attached to the oil pump shaft.
