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.
Notice
A 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 figure
8.66.
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.
Notice
A 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.
