-- 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.
