(1) Magnetic drain plug
(2) Access plate with three M8x1 bolts
Remove magnetic drain plug (1) from the bottom rear of the transmission and inspect 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 Caterpillar dealer for further analysis and additional guidance.
Allow the oil to drain into a suitable container.
After the oil has drained from the transmission case, clean the drain plug before reinstalling the drain plug. Torque the drain plug to 73.5 3.5 N m (54 2.6 lb ft).
Remove the three bolts for the access plate (2).

(3) Suction screen
(4) Magnetic filter
Remove suction screen (3). Remove magnetic filter (4). 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 (3) and magnetic filter (4) 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 Caterpillar dealer for further analysis and additional guidance.
Do not drop or rap the magnets against any hard objects. The magnets are brittle. Replace broken magnets or damaged screens.
Wash the suction screen and the magnetic filter in clean, nonflammable solvent. Clean the magnets with a cloth or a stiff bristle brush.
Inspect the condition of the O-ring seal in the access plate. If the seal is damaged, replace the seal.
Install the magnetic filter, the screen, and the access plate. Tighten the three bolts for the access plate to 28 7 N m (21 5 lb ft).

Fill the transmission to the full mark on the dipstick at filler tube (5) with the recommended oil viscosity and volumes. Refer to Operation and Maintenance Manual, "Capacities (Refill)" for the appropriate oil volumes.
The vehicle must be on level ground and the transmission must be in neutral. Start the engine and
