OIL PAN
Oil PanINFOID:0000000004917434
REMOVAL AND INSTALLATION
Removal
1. Drain A/T fluid. Refer to TM-180, "Changing the A/T Fluid (ATF)".
2. Remove oil pan clips (1).
3. Remove oil pan (2).
4. Remove oil pan gasket. • Vehicle front
• Oil pan bolts
• Drain plug (3)
5. Check for foreign materials in oil pan to help determi ne cause of malfunction. If the A/T fluid is very dark,
has some burned smell, or contains foreign particles then friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates varnish build up. Varnish can cause valves,
servo, and clutches to stick and can inhibit pump pressure.
CAUTION:
If friction material is detected, flush th e transmission cooler after repair. Refer to TM-182, "
A/T
Fluid Cooler Cleaning".
6. Remove magnets from oil pan.
Installation
1. Install the oil pan magnets as shown.

OIL PAN
2. Install the oil pan (2) new oil pan gasket.• : Vehicle Front
• : Oil pan bolts
• Clips (1)
• Drian plug (3)
CAUTION:
• Be sure the oil drain plug is located to the rear of thetransmission assembly.
• Before installing oil pan bolts, remove any traces of old sealant from the sealing su rfaces 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. Install 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 drain plug gasket.
5. Refill the A/T with fluid and check for fluid leakage. Refer to TM-178, "

TRANSMISSION ASSEMBLY
• When installing transmission to the engine, attach the bolts in the order as shown.CAUTION:
• When replacing an engine or transmission you must make
sure the dowels are installe d correctly during re-assembly.
• Improper alignment caused by missing dowels may cause
vibration, oil leaks or breakage of drivetrain components.
NOTE:
*: No.2 bolt also secures air breather vent.
CAUTION:
• When turning crankshaft, turn it clockwi se as viewed from the front of the engine.
• After converter is installed to drive plate, rota te crankshaft several turns and check to be sure that
transmission rotates fr eely without binding.
NOTE:
• Align the positions of bolts for drive plate with those of the torque converter, and temporarily tighten the bolts. Then tighten the bolts
with the specified torque.
• Install crankshaft pos ition sensor (POS).
• After completing installation check fluid leakage, fluid level and the positions of A/T. Refer to TM-178, "
Checking the A/T Fluid (ATF)",
TM-194, "
Checking of A/T Position" and TM-194, "Adjustment of A/
T Position".

• After inserting a torque converter to a transmission, be sure to check dimension A to ensure it is within specifications.
INSTALLATION
Installation of the remaining components is in the revers e order of removal, while paying attention to the fol-
lowing:
• When installing transmission to the engine, attach the bolts as shown.
CAUTION:
• When replacing an engine or transmission you must make sure the dowels are installed correctly during re-assembly.
• Improper alignment caused by missing dowels may cause
vibration, oil leaks or breakage of drivetrain components.
NOTE:
*: No.2 bolt also secures air breather vent.

converter, and temporarily tighten the bolts. Then tighten the bolts
with the specified torque.
CAUTION:
• When turning crankshaft, turn it clockwise as viewed from the
front of the engine.
• After converter is installed to drive plate, rotate crankshaft several turns and check to be sure that transmission rotates
freely without binding.
• Install crankshaft position sensor (POS).
• After completing installation, check fluid leakage, fluid level, and the positions of A/T. Refer to TM-178, "
