Typical example of a CX31–P600 Petroleum Transmission with drop box (1) Suction screen (2) Magnetic filter (3) Access plate with three M8x1 bolts (4) Magnetic drain plug (5) Ecology drain plate
Remove ecology drain plate (5) from the bottom of the drop box and allow the oil to drain into a suitable container.
Remove magnetic drain plug (4) from the bottom of the drop box and inspect the plug for large particles of debris. An excessive amount of debris may be an indication of possible failure. Discolored oil or oil with an odor requires a careful analysis of S O S results. If large particles are found, consult your Cat dealer for further analysis and additional guidance.
After the oil has drained from the transmission case, clean the drain plug before reinstalling magnetic drain plug (4). Torque the drain plug to 73.5 3.5 N m (54 2.6 lb ft).

Remove suction screen (1). Remove magnetic filter (2) .Note: Additional oil may drain from the oil pan when the cover is removed. Ensure that a suitable container is in place in order to capture any oil that may drain from the torque converter housing.
Inspect suction screen (1) and magnetic filter (2) for large particles of debris. An excessive amount of debris may be an indication of possible failure.
