INTRODUCTION:

This Service Information Bulletin outlines design changes made to the TR580 CVT oil pan assembly.  The changes are as follows:

  • The CVT oil pan material has been changed from steel to aluminum.
  • The new aluminum pan has a new, larger diameter drain plug and drain plug gasket.
  • The new aluminum pan will be sold as a set consisting of: oil pan, drain plug and drain plug gasket.
  • The bolts used to secure the pan to the case are now a flanged type instead of lock-washer type and are reusable.

 

VERY IMPORTANT:

  • The new oil pan assembly comes with a new drain plug and drain plug gasket but, the new drain plug is only hand-tightened. When replacing the pan, confirm the drain plug is lubricated with CVT fluid and properly torqued to specification: 47 Nm (34.7 ft. lbs.).
  • Whenever removing the transmission assembly, it is CRITICAL to not allow the support plates of the transmission jack to contact (and potentially damage) the aluminum oil pan.

 

PRODUCTION CHANGE INFORMATION:

These new parts were incorporated at the start of 2020MY Legacy and Outback production. These new parts were incorporated at the start of 2022MY Forester Wilderness production.
