3 Service Operations
3.1 Fluid Change and Filter Replacement

To avoid personal injury take note of the
following:
• Avoid accidental hot oil spillage by
performing fluid change only when the
transmission fluid is cold.
• Wear safety glasses and gloves when
using compressed air and cleaning fluids.
Remove
1 Raise the vehicle and support in a safe manner, refer to 0A General Information.
2 Clean all dirt from around the oil pan and the transmission case.
3 Place a suitable sized drain tray under the transmission.
4 Hold the oil pan (1) in place and remove the oil pan bolts (2) from the front and both sides.
NOTE
Leave the three rear oil pan bolts in place.
5 Loosen the three rear oil pan bolts by about 4 turns each. While still supporting the oil pan, lightly tap the
sides with a rubber hammer to break the gasket (3)
seal.
6 Lower the front of the oil pan and drain the fluid into a suitable container.

9 Remove the oil filter (1) by pulling down while twisting
the filter and remove it from the transmission.
10 Open the filter by prising the metal crimping away from the top of the filter and pull it apart.
11 Inspect the filter material for particles that may indicate evidence of a potential transmission problem.
Examples of the type of material are:
• clutch friction material,
• bronze slivers, indicating bush wear and
• steel particles.
Figure 7C4 – 3

Take care not to scratch the oil pump bore,
as fluid leakage could occur from this point
or the pump may suck in air, causing the
fluid to aerate.
12 Using suitable circlip pliers (1) or a two legged puller and slide hammer, remove the oil filter seal (2) taking
care not to scratch the oil pump bore (3) during the
process. Discard the seal.
Figure 7C4 – 4
Reinstall
1 Clean the oil pan in a commercially available cleaning fluid and blow dry using compressed air.
NOTE
Ensure all traces of the old gasket are removed
from the transmission and oil pan.
2 W ipe the transmission case gasket mating surface with a clean lint free cloth.

9 Install the seal protector, Tool No. AU583-1 (1) into
one of the two plastic seal installers, Tool No.
AU583-2 (2).
NOTE
Two plastic seal installers are required because
of the restricted space between the end of the
manual shaft and the floor pan.
10 Lubricate the lip of a new seal (3) with clean automatic transmission fluid and install it over the seal protector
sleeve, with the steel casing facing the installer tool.
11 Install the seal protector with the new seal and installer tool over the manual shaft (4) and up to the
transmission case.

If the seal protector sleeve jams on the
manual shaft, the flats on the shaft locating
the selector lever will be burred. Use a fine
file to remove any burrs and then proceed.
12 Fit the second plastic seal installer over the manual shaft until it seats against the first installer.
13 Install the manual shaft linkage attaching nut (5) and tighten it to drive the seal in position into the
transmission case.
14 Remove the seal installer and protector tools from the manual shaft.
Figure 7C4 – 18
15 Reinstall the neutral start and back-up lamp switch, refer to 3.4 Neutral Start and Back-up Lamp Switch.
16 Lower the vehicle to the ground and as required, check and top up the automatic transmission fluid level, refer to 2.1 Transmission Fluid.
3.7 Transmission Support and Mount
Remove
1 Raise the vehicle and support in a safe manner, refer to 0A General Information for the location of support points.
2 Support the transmission with a Jack, do not place the support underneath the extension housing or the oil pan, refer to Figure 7C4 – 19.
3 Remove the clip (1) holding the fuel feed and fuel vapour lines on the transmission support (2).
4 Remove the bolt (3) attaching the heat shield (4) to the transmission support.
5 Remove the two nuts (5) attaching the transmission mount to the support.
6 Remove the four bolts and nuts (6) attaching the transmission support to the under body side rails and remove the support.
