WARNING:
  • A hot transmission and ATF can cause severe burns. Turn off the engine and wait until they are cool before replacing ATF.
CAUTION:
  • Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.
  1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION .)
  2. Drain the ATF. (See AUTOMATIC TRANSMISSION FLUID (ATF) REPLACEMENT .)
    CAUTION:
    • Do not damage the installation surface of the transmission case and the oil pan.
    • Do not deform the oil pan.
  3. Remove the oil pan and gasket.
