(2) Remove the extension housing and the extension housing gasket.

NOTE: The extension housing bolts have been coated with a sealant. High breakaway torque may be required to remove these bolts.





29. Remove the parking pawl.
(1) Remove the parking pawl shaft.
(2) Remove the parking pawl return spring.
(3) Remove the parking pawl.

30. Rotate transmission to the vertical position with the output shaft toward floor.
