PRECAUTIONS
PRECAUTIONS PFP:00001
A
Caution ECS004PV
q Do not reuse transaxle oil, once it has been drained.
q Check oil level or replace oil with vehicle on level ground. B
q During removal or installation, keep inside of transaxle clear of dust or dirt.
q Check for the correct installation status prior to removal or disassembly. If mating marks are required, be
certain they do not interfere with the function of the parts they are applied to. MT
q In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
q Be careful not to damage sliding surfaces and mating surfaces. D

1. Start the engine and let it run to warm up the transaxle oil.
2. Stop the engine. Remove the drain plug and drain the transaxle oil into a suitable container.
3. Set a new gasket on the drain plug, and install the drain plug in the transaxle body.
