C3 Clutch and Reverse Sun Gear Assembly
To assemble the C3 clutch and reverse sun gear assembly (refer to figure 8.28), proceed as follows.1. Check the orifices in the cylinder are clear of obstructions.
2. Check the C3 cylinder bush outside diameter and the centre support inside diameter are in good condition and
not damaged. Coat the sealing rings with automatic
transmission fluid and fit into the C3 cylinder grooves.
3. Check the reverse sun gear splines, grooves and thrust face for condition. Coat the ‘O’ ring with automatic
transmission fluid and fit it to the groove of the reverse
sun gear.
4. Install the reverse sun gear in the C3 cylinder, ensuring that the ‘O’ ring compression is adequate but not
excessive. Notice
‘O’ rings must not be twisted in the grooves.
5. Coat the C3 piston ‘O’ rings with automatic transmission
fluid and fat the small ‘O’ ring onto the in ner ring and the
large ‘O’ ring onto the outer ring of the C3 piston.
6. Check that the bleed orifices of the piston are clean and clear of obstructions.
7. Install the C3 piston in the cylinder until the outside diameter of the piston enters the inside diameter of the
cylinder. Notice
Take care not to cut the ‘O’ ring.
8. Assemble the spring and spring retainer on the piston. Using tool No. 0555-331899 compress the spring
sufficiently to enable the installation of the retaining circlip,
ensuring that the circlip is firmly seated in the groove, andremove the tool.
9. Fit the C3 wave plate to the C3 piston face, ensuring that one crest of the wave plate of the C3 piston face is aligned
over one of the piston orifices.
10. Assemble the clutch plates and discs into the cylinder in the following sequence :
Steel plate
Friction disc
Steel plate
Steel plate - 0574-000001, 0574-000003, 0574-000004,0574-000005,0574-000020,
0574-000021, or friction disc -0574-000002

12. Install the circlip.
13. Check the C3 clutch clearance (refer to figure 8.29) usingspecial tool No.0555-331900 in the following manner (weight only).
a. Place the weight on the pressure plate and measure
the distance from the end of the cylinder to the top of the pressure plate.
b. Record this figure.
c. Remove the weight.
d. Lift the pressure plate up against the circlip and measure the distance from the end ofthe cylinder to the top of the pressure plate.
e. Record this figure.
f. Subtract the second reading from the first reading to obtain the clutch pack clearance.
NoticeWith the clutch pack supporting a weight of 2 kg, the clearance between the snap ring and the top of the pressure plate is to be between 1.20-1.45 mm.
14. If new friction plates are being fitted, remove the clutch pack and soak the friction elements in automatic
transmission fluid for a minimum of five minutes prior to
reassembly. NoticeThe clutch pack clearance must be taken before the elements are soaked in automatic transmission fluid. Figure 8.29 - Typical C3 Clutch Assembly

5A-110 AUTOMATIC TRANSMISSION C1 Clutch Overdrive Shaft and Input Shaft Assembly Notice
1. Ensure that the snap rings are fitted correctly.
2. Check pistons for cracks, especially the C1 piston.
3. Do not mix clutch piston return springs.
4. If the C1/C2 clutch packs separate from the C3 clutch pack,make sure the No. 6 bearing doesn ’t drop out of the bearing
retainer.
To assemble the C1 clutch overdrive shaft and input shaft
assembly, proceed as follows:
1. Check the overdrive shaft grooves for any defect.
2. Coat the sealing rings, large and small, with petroleum jelly and fit them to the overdrive shaft. The sealing rings may
be held in place with a small amount of petroleum jelly.
3. Assemble the clutch plate and disc into the cylinder in the following sequence:
steel plate
friction disc

4. Check the clutch pack clearance using special tool No.0555- 331900. Refer to figure 8.31.Use selective plates to achieve the correct specification.NoticeThe clutch pack supporting a 2 kg weight, the dimension from the input shaft locating stop to the friction disc mustbe 0.70-0.90 mm.
5. If new friction plates are being fitted, remove the clutch pack and soak the friction elements in automatic transmission
fluid for a minimum of five minutes prior to assembly. NoticeThe clutch pack clearance must be taken before elements are soaked in automatic transmission fluid.
6. Check the fit of the C1 clutch hub on the overdrive shaft. If it is loose, the hub and shaft assembly must be replaced. Figure 8.31 - Typical C1 Clutch Assembly

Pump Cover and Converter Support Notice
1. Do not wash the nose of solenoids in solvent.
2. Ensure that the correct ‘O’ ring is fitted for the application.
3. Do not mix up the low first blow-off and the torque converter blow-off ball springs.
4. Be careful not to damage the needle bearings on the assembly. Avoid any axial impact loads during assembly.
5. Check the transmission end float. This will help to detect any missing parts or incorrect assembly.NoticeFigure 8.35 shows the orientation of the cross- sections for figures 8.36 to 8.42.
To assemble the pump cover and converter support (refer to figures 8.34 and 8.35), proceed as follows.
1. Check the pump body for any damage, chips or irregularity. Check that the bush is firmly staked in the drive gear.
2. Install the seal flush with the front face of the pump body.
3. Lubricate the pump bush, and the drive and driven gears, with automatic transmission fluid.
4. Install the pump driven gear and the pump drive gear into the pump body.
5. Using a straight edge and thickness gauge, check that the clearance between pump face and gears is 0.04 - 0.018
mm.
6. Lubricate the pump body ‘O’ ring with automatic transmission
fluid and fit it to the pump body. Put the pump body to one side.
7. Ensure that the pump cover cavities, ports and holes are clean and free of any obstruction.
8. Lubricate all loose parts with automatic transmission fluid prior to assembly. Figure 8.34 - Pump, Cover and Converter

Oil Filter and Pan Assembly Notice
1. Replace the filter whenever rebuilding a transmission where a significant amount of mechanical damage hasoccurred.
2. To aid the assembly of the pan gasket, use a small amount of Vaseline at the pan/gasket interface. This ensures that the gasket remains on the pan ridge. Do not over torque pan bolts as this may distort the pan and cause leaks.
3. Ensure that the internal line pressure plus in the valve body is fitted.
To assemble the oil filter and pan assembly (refer to figures 8.63 and 8.64), proceed as follows.
1. Lubricate the oil filter sealing ring with automatic transmission fluid.
2. Carefully assemble the oil filter to the valve body. The spigot must not lean on one side while being fitted. Refer to figure 8.63.
3. Secure the oil falter assembly with the retainer.
4. Check that the magnet is located in the dimple in the comer of the oil pan.
5. Assemble the gasket on the pan lip. The gasket must be free of any distortion when installed.
6. Fit the oil pan assembly to the transmission case and tighten the securing bolts to specification and sequence (refer to figure 8.65). Do not over torque.

4. If the input shaft needle bearing and bushing were removed,
install a new bearing and bushing as detailed in the following steps: Press a new needle bearing, then a new bushing in the input shaft as follows:
a. Position the input shaft on Axle Bearing/Seal Plate or equivalent, and Pinion Bearing Cone Replacer as a
spacer.
b. Press a new needle bearing into the end of the input shaft until it seats in the input shaft.
c. Press in a new bushing.
5. The recessed face of the sun gear and the snap ring groove on the bearing outer race should be toward the rear of thetransfer case. The stepped face of the thrust washer shouldface toward the bearing.
Slide the sun gear, thr ust plate and thrust washer into
position on the input shaft. Press the bearing over the input shaft. Install the external snap ring to the input shaft.

10. If new pump is used, align the flat of the output shaft and
the flat of the pump. Slide the pump onto the output shaft.
Do not disassemble oil pump. It is serviced only as an
assembly. Check the pump to make sure the pump
rotates freely.
Do not remove the plastic insert from the bore of the
new pump. Discard it after it slides out during pumpinstallation to the rear output shaft.
While turning the output shaft, prime the pump through
the oil filter pickup tube or housing inlet hole with clean
Automatic Transmission Fluid or equivalent.
11. Inspect the outside surfaces and bore of the oil pump. If there is no discoloration in the pump housing, gear or cover,and the pump bore and the lube holes of the output shaft show evidence of oil, the pump is working.
