No real need to drain the oil. You are going to get some dripping no matter how you go about it, because it is going to be in the cooler lines and some will come out of the filter adapter when you disconnect them.
Caution: In order to avoid being burned, do not service the engine while it is still hot. Service the engine when it is cool.
Notice: Do not reuse the existing retaining clips removed from the cooler line connector fittings. The retaining clips being put into the cooler line connector fittings must be new.
Notice: Make sure the retaining clip engages all three slots in the connector fittings. Failure to properly install the connector clips could cause the cooler lines to come loose and cause damage to the engine and/or the transmission.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
