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.
7 Remove the three remaining rear bolts and the oil pan from the transmission.
8 Remove the oil pan gasket and discard.

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.
