Servicing automatic gearbox 09E, four-wheel drive - Edition 12.2011
Gearbox
♦ Rules for cleanliness when working on the automatic gearbox
⇒ page 11
♦ If the gearbox has been removed from the vehicle and the
flange shaft (left-side) then removed, the torque converter
must be secured using the support bridge -30 - 211 A- to pre‐
vent it from falling out.
♦ Use only ATF or vaseline on all parts running in ATF. Other
lubricants will cause malfunction of the gearbox hydraulics.
♦ After the gearbox has been overhauled it should be installed
and operated as soon as possible to prevent any corrosion
forming on the new components.
♦ After installation, fill up and check all fluid levels. For capacities
and specifications refer to ⇒ Automatic gearbox 09E, four-
wheel drive; Rep. gr. 00 .
Procedure if ATF is dirty
If the ATF and related components are very dirty (caused by worn
clutch linings):
♦ Dismantle and clean complete gearbox.
♦ Dismantle and check all clutches.
♦ Renew torque converter (cannot be cleaned).
♦ Renew mechatronic unit (cannot be cleaned).
♦ Clean ATF lines and ATF cooler and renew ATF strainer.
O-rings, seals, oil seals and gaskets
♦ Always renew O-rings, seals, oil seals and gaskets.
♦ After removing gaskets and seals, always inspect the contact
surface on the housing or shaft for burrs resulting from removal
or for other signs of damage.
♦ The open side of the oil seal should face the side containing
the fluid.
♦ Lightly lubricate the outer circumference and sealing lip of oil
seals with ATF before installing.
♦ Lightly lubricate O-rings with ATF or vaseline before installa‐
tion to prevent them getting crushed during assembly.
♦ Use only ATF or vaseline on all parts running in ATF. Other
lubricants will cause malfunction of the gearbox hydraulics.
♦ When installing a new oil seal, position the seal such that the
sealing lip does not contact the shaft in the same place as the
old seal (make use of installation depth tolerances).
♦ Completely remove old gaskets, clean sealing surfaces thor‐
oughly and renew gaskets.
Nuts, bolts
♦ Slacken bolts in reverse sequence to the specified tightening
sequence.
♦ Nuts and bolts which secure covers and housings should be
loosened and tightened in diagonal sequence and in stages if
no tightening sequence is specified.
♦ The tightening torques stated apply to non-oiled nuts and
bolts.
♦ Always renew self-locking bolts and nuts.
