UNIT REPAIR

REBUILD WARNINGS

Prior to rebuilding a transmission system, the following warnings
are to be noted.

l

Ensure that, before replacing a transmission the cooler

lines are flushed out to remove any debris. This can be
done by applying compressed air to the rear cooler line
forcing oil and any contaminants out of the front cooler
line.

l

The cooler flow should be checked after the transmission

has been fitted. With the front cooler line connected
and the rear line run into a suitable container, measure
the flow over 15 seconds with the vehicle idling in park.

l

The flow rate should exceed 1 liter in 15 seconds.

l

Be wary of any situation where water enters the

transmission. This may result in fluid foaming and leaking
through the breather.

l

Ensure that both earth straps (one at the batted terminal

and one on the vehicle body) are connected in the
vehicle before connecting the positive side of the
battery.

l

Follow the throttle position calibration procedure in

section 7 of this manual if the powertrain control module
transmission control unit (PCM/TCU) is swapped.

DISASSEMBLY PROCEDURE

Transmission

Notice

Remove the inhibitor switch before washing the transmission
in solvent or hot wash.

It is assumed that the transmission fluid has been drained
when the transmission was removed from the

vehicle and that the ‘special tools’ quoted are available.

The transmission is dismantled in a modular fashion, and the
details of disassembly for each module are given under the
appropriate subject. Refer to table 9.10 in section 9.6 for details
of all special tools required when performing disassembly
procedures.

Technicians overhauling these transmissions will also require
a selection of good quality Torx bit sockets, in particular
numbers 30, 40 and 50, and an 8 mm,10 mm and 12 mm
double hex socket.

To disassemble the transmission, proceed as follows:

1. Remove the converter and the converter housing.
