5A-126 AUTOMATIC TRANSMISSION
Oil Filter and Pan Assembly
Notice
1. Replace the filter whenever rebuilding a transmission where a significant amount of mechanical damage has
occurred.
2. To aid the assembly of the pan gasket, use a small amount of Vaseline at the pan/gasket interface. This ensures
that the gasket remains on the pan ridge. Do not over torque pan bolts as this may distort the pan and cause
leaks.
3. Ensure that the internal line pressure plus in the valve body is fitted.
To assemble the oil filter and pan assembly (refer to figures 8.63 and 8.64), proceed as follows.
1. Lubricate the oil filter sealing ring with automatic transmission fluid.
2. Carefully assemble the oil filter to the valve body. The spigot must not lean on one side while being fitted. Refer to
figure 8.63.
3. Secure the oil falter assembly with the retainer.
4. Check that the magnet is located in the dimple in the comer of the oil pan.
5. Assemble the gasket on the pan lip. The gasket must be free of any distortion when installed.
6. Fit the oil pan assembly to the transmission case and tighten the securing bolts to specification and sequence
(refer to figure 8.65). Do not over torque.
