2. Install the oil pan and new oil pan gasket.
CAUTION:

Be sure the oil pan drain plug is located to the rear of the
transmission assembly.

Before installing oil pan bolts, remove any traces of old
sealant from the sealing surfaces and threaded holes.

Do not reuse old gasket, replace with a new one.

Always replace the oil pan bolts as they are self-sealing.

Partially install the oil pan bolts in a criss-cross pattern to
prevent dislocation of the gasket.
3. Tighten oil pan bolts in numerical order as shown.
4. Install drain plug in oil pan.
CAUTION:
Do not reuse old drain plug gasket replace with a new one.
5. Refill the transmission assembly with fluid. Refer to MA-24, "
Changing A/T Fluid" .
