NOTE: In order to completely clean the torque converter, this procedure needs to be carried out 3 times.
  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING AND LIFTING .
  2. NOTE: If an internal problem is suspected, drain the transmission fluid through a paper filter. A small amount of metal or friction particles may be found from normal wear. If an excessive amount of metal or friction material is present, the transaxle will need to be overhauled.
  3. Remove the transmission fluid drain plug and allow the transmission fluid to drain.
