-- Loosen the bolts -arrow- for the hydraulic pressure reservoir and bearing bracket but do not remove.

If the hydraulic pressure reservoir lifts when loosening the bolts the ATF system is still under pressure.
In this case the bolts from the Mechatronic must be minimally loosened to reduce the pressure in the ATF system via the sealing surfaces.
Deactivate the ATF pump and drain the hydraulic pressure reservoir. Refer to ATF PUMP, DEACTIVATING AND DRAINING THE HYDRAULIC PUMP RESERVOIR .

-- Remove the bolts -arrows-, the bearing bracket and the hydraulic pressure reservoir.
