place. Torque to 11 Nm (8 ft-lb).
5. Remove oil fill plug with an 8mm Allen wrench.
6. Carefully pour 16 oz (470 ml) of transmission oil into the oil fill opening.
7. Reinstall the oil fill plug making sure the rubber gasket is in place.
NOTE: Filling after an engine rebuild required additional transmission fluid. If the
engine is completely flushed of oil, refill with 18 oz (530ml).
Always capture and dispose of used oil properly (all auto parts stores accept
used oil). Dumping oil on the ground is illegal, inconsiderate, and can get you
disqualified from a race weekend quicker than cutting the track.
