5A-126 AUTOMATIC TRANSMISSION
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.

Torque Converter and Housing Assembly
To assemble the torque converter and housing assembly, proceed as follows.
1. Locate the torque converter housing on the transmissionmain case.
2. Install and tighten the securing bolts to specification. NoticeAll the hardware must be correctly installed and torqued to specification.
3. Fit the converter ensuring that the tangs are engaged in the pump gear. Ensure that the tangs do not contact thepump seal.

5A-128 AUTOMATIC TRANSMISSION FRONT AND REAR BAND ADJUSTMENT
Front Band Setting Procedure
To set the front band, proceed as follows.
1. Measure the projection of the front servo push rod from the transmission case. Refer to figure 8.66, dimension A.a. Apply air at 650/700 kPa to the front servo apply area (B1 outer). (Refer to figure 8.67.)
b. Measure the travel of the push rod and subtract 3 mm to find the shim size required.
c. Release the air. NoticeA minimum of one shim is required at all times - minimum shim size is 1 mm. The thicknesses of available shims
are listed in table 8.2.
2. Fit the selected shim(s) to the shank of the anchor strut as follows: a. Inspect the shim(s) for damage, wear or corrosion. Replace as necessary.
b. The shim(s) are to be installed between the case abutment face and the anchor strut flange. Refer to figure8.66.
c. The shim(s) are to be fitted by hand and under no circumstances to be hammered or forced.
d. Shim(s) are to be pressed on by hand until an audible click is heard. The click indicates that the shim is clipped home correctly.
3. Re-check that the push rod travel is 3 mm ± 0.25 mm.

Rear Band Setting Procedure
To set the rear band, proceed as follows. 1. Measure distance
‘A’ from the rear servo piston to the inner face of the transmission case using vernier calipers.
Refer to figure 8.68.
a. Apply air at 650/700 kPa to the rear servo apply area (B2 outer). Refer to figure 8.67.
b. Measure the travel of the piston, subtract 3.75 mm and divide the remainder by 2.5 to find shim size.
c. Release the air.
NoticeA minimum of one shim is required at all times - minimum shim size is 1 mm. The thickness of available shims are listed in table 8.2.
2. Fit the selected shim(s) to the shank of the anchor strut as follows.
a. Inspect the shim(s) for damage, wear or corrosion and replace as necessary. The shim(s) are to be installed between the case abutment face and the anchor strut flange. Refer to figure 8.68.
c. The shim(s) are to be fitted by hand and under no circumstances to be hammered or forced.
d. The shim(5) are to be pressed on by hand until an audible click is heard. The click indicates that the shim is clipped home correctly.
3. Re-check that the piston travel is 3.75 mm ± 0.625 mm.
