Installation Procedure
Notice: Any time the transmission and the engine oil pan are off of the engine at the same time, install the transmission before the oil pan. This is to allow for the proper oil pan alignment. Failure to achieve the correct oil pan alignment can result in transmission failure.
1. Apply a 5 mm (0.197 inch) wide and 25 mm (1.0 inch) long bead of adhesive to both the right and left sides of the front cover to engine block junction at the oil pan sealing surfaces. Refer to Sealers, Adhesives, and Lubricants for the correct part number.
2. Apply a 5 mm (0.197 inch) wide and 25 mm (1.0 inch) long bead of adhesive to the entire length of rear oil seal housing to engine block junction at the oil pan sealing surfaces. Refer to Sealers, Adhesives, and Lubricants for the correct part number.
3. Important: Always install a NEW oil pan gasket.
The oil pan gasket and oil pan must be installed and the fasteners tightened while the adhesive is still wet to the touch.
Install a NEW oil pan gasket into the groove in the oil pan.
4. Important: The oil pan alignment must always be flush or forward no more than 0.3 mm (0.011 inch) from the rear face of the engine block.
Install the oil pan. Press the oil pan gasket into the grooves of the engine front cover and crankshaft rear oil seal housing.
5. Slide the oil pan back against a suitable straight edge.
6. Install the oil pan bolts and nuts until snug.
7. Measure the oil pan-to-transmission housing clearance using a feeler gage and a straight edge. Use the feeler gage to check the clearance at the oil pan-to-transmission housing measurement points (1). If the clearance exceeds 0.3 mm (0.011 inch) at any of the oil pan-to-transmission housing measurement points (1), then repeat the step until the oil pan-to-transmission housing clearance is within specifications. The oil pan must always be forward of the rear face of the engine block.
8. Notice: Refer to Fastener Notice in Service Precautions.
Tighten the oil pan bolts and nuts in the sequence shown.
Tighten the bolts to 25 Nm (18 ft. lbs.).
9. Measure the clearance at the oil pan-to-transmission housing measurement points in order to ensure proper alignment.
10. Install a NEW drain plug O-ring seal onto the drain plug.
11. Install the drain plug.
Tighten the plug to 25 Nm (18 ft. lbs.).
12. Important: The oil level sensor is not reusable. Use a NEW oil sensor.
Install a NEW oil level sensor.
Tighten the sensor to 13 Nm (115 inch lbs.).
13. Install the transmission cover.
Tighten the bolts to 12 Nm (106 inch lbs.).
14. Install the automatic transmission bolts, if equipped.
15. Install the manual transmission bolts, if equipped.
