lDo not reuse transaxle oil, once it has been drained.
lCheck oil level or replace oil with vehicle on level ground.
lDuring removal or installation, keep inside of transaxle clear of dust or dirt.
lCheck 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.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
lBe careful not to damage sliding surfaces and mating surfaces.
