2. Install the oil pan and new oil pan gasket. • : Vehicle front
• : Oil pan bolts
• Clips (1)
• Drain plug (3)
CAUTION:
• Be sure the oil pan drain plug hole is located to the rear ofthe transmission assembly.
• Before installing oil pan bolts, remove any traces of old sealant from the sealing su rfaces and threaded holes.
• Do not reuse the oil pan gasket.
• Always replace the oil pan bolts as they are self-sealing.
• Partially install the oil pan bo lts in a criss-cross pattern to prevent dislocation of the gasket.
3. Install new oil pan bolts and clips tighten in numerical order as shown.
4. Install drain plug with new gasket to oil pan and tighten to speci- fication.
CAUTION:
Do not reuse the drain plug gasket.
5. Refill the A/T with fluid and check for fluid leakage. Refer to TM-
148, "Checking the A/T Fluid (ATF)".
