The engine must be running when the transaxle fluid level screw is removed, or excessive fluid loss will occur. Since the actual fluid level is unknown, stand clear when removing the fluid level screw. Have a container ready to capture any lost fluid.



  • Let vehicle idle for three to five minutes with accessories off.
  • Apply brake
  • Move shift lever through all gear ranges, pausing three seconds in each range.
  • Place shift lever in Park. Important: Vehicle must be kept level on the hoist.
  • Raise vehicle on hoist.
  • Place oil container under fluid level screw.
  • Remove the fluid level screw with the engine running at idle.
  • Fluid level should be at the bottom of the fluid check hole. Because the transaxle operates correctly over a range of fluid levels, fluid may or may not drain out of the fluid check hole when the fluid level screw is removed. If fluid drains through the fluid check hole, this transaxle may have been overfilled. When fluid stops draining, the fluid level is correct and the fluid level screw may be installed. If fluid does not drain through the fluid check hole, the transaxle fluid level may be low.
  • Install fluid level screw.
  • Lower vehicle.
  • Shut off engine.

Adding Transaxle Fluid:

  • With the engine running, add fluid at the vent cap location in half liter (1 pint) increments until fluid drains through the fluid check hole. Allow the fluid to finish draining through the fluid check hole.
  • Install fluid level screw.
  • Lower vehicle.
