General
information
1 The Easytronic MTA transmission (Manual
Transmission Automatic-shift) is essentially
a conventional manual transmission with the
addition of a clutch module and shift module,
used in conjunction with a self-adjusting
clutch plate (see illustration).
2 The description of the MTA transmission is
?asically as for the manual transmission given
in
Chapter 7 A, but with an electronically-
operated hydraulic clutch control module
and gear selection module. The transmission
can be switched between fully-automatic and
manual mode, even while driving.
3 The clutch control module incorporates its
2.5 Differential cover plate securing bolts
(arrowed)
own master cylinder and pushrod, which is
operated electrically by a worm gear.
4 The gear selection module is fitted with
a shifting motor and a selector motor, which
together position the selector lever to move
the selector forks in the transmission. It is
located in exactly the same position as the
gear selection cover fitted to the conventional
manual transmission.
5 Since the transmission is electronically-
controlled, in the event of a problem, in the
first instance the vehicle should be taken to a
Vauxhall/Opel dealer or diagnostic specialist
who will have the TECH2 diagnostic equipment
(or equivalent) necessary to pin-point the
faulty area. Note also that if the transmission
assembly, shift module or clutch module
are renewed, the vehicle must be taken to a
Vauxhall/Opel dealer or diagnostic specialist
2.8 Transmission oil filler/level plug
(arrowed)
in order to have the fault memory erased and
new parameters programmed into the ECU.
Note: A new differential lower cover plate
gasket will be required for this operation.
Draining
1 This operation is much more efficient if
the car is first taken on a journey of sufficient
length to warm the engine/transmission up to
normal operating temperature.
Caution: If the procedure is to be carried
out on a hot transmission unit, take care
not to burn yourself on the hot exhaust or
the transmission/engine unit.
2 Position the vehicle over an inspection pit,
on vehicle ramps, or jack it up and support
it securely on axle stands (see Jacking and
vehicle support), but make sure that it is
level. Where fitted, remove the clips and bolts
and remove the undertray from beneath the
engine.
3 Since the transmission oil is not renewed
as part of the manufacturer's maintenance
schedule, no drain plug is fitted to the
transmission. If for any reason the transmission ·
needs to be drained, the only way of doing so
is to remove the differential lower cover plate.
4 Wipe clean the area around the differential
lower cover plate and position a suitable
container underneath the cover plate.
5 Evenly and progressively slacken and
remove the retaining bolts then withdraw the
cover plate and allow the transmission oil to
drain into the container (see illustration).
Remove the gasket and discard it; a new one
should be used on refitting.
6 Allow the oil to drain completely into the
container. If the oil is hot, take precautions
against scalding. Remove all traces of dirt
and oil from the cover plate and transmission
mating surfaces and wipe clean the inside of
the cover plate.
7 Once the oil has finished draining, ensure
the mating surfaces are clean and dry then
refit the cover plate to the transmission unit,
complete with a new gasket. Refit the retaining
bolts and evenly and progressively tighten
them to the specified torque.
Refilling
8 Wipe clean the area around the filler/level
plug. The filler/level plug is located behind the
driveshaft inner joint on the left-hand side of
the transmission (see illustration). Unscrew
the plug and clean it.
9 Refill the transmission via the filler/level
plug orifice with the specified type of oil until
it begins to trickle out of the orifice. Once the
oil level is correct, refit the filler/level plug and
tighten to the specified torque.

Refit the engine undertray (where fitted)
and lower the vehicle to the ground.
