plug and ‘O’ ring.
10. Install the retaining pin.
11. Install the converter clutch regulator valve (refer to figure
8.37), plug, and ‘O’ ring.

18. Install the gasket on the pump cover.
19. Install the cover plate, solenoid 7 with the retainer and the
solenoid wiring retainer to the pump cover, ensuring that
the periphery of the cover plate is flush with the periphery
of the pump cover. Refer to figure 8.34.
Tighten the screws to specification in the order (1-5), shown
in figure 8.44.
24. Install the pump and cover assembly over the input shaft
being careful not to damage the sealing rings. Tighten the
pump cover to case bolts to specification. Refer to figure
8.45. 20. Tighten the solenoid 7 screw. Refer to figure 8.39.
Notice
Check that neither the wiring nor the connector protrudes
excessively, in order that at assembly neither the wiring
and the connector contacts or rubs on the input shaft or
the C1/C2 clutch cylinder.
21. Assemble the pump to the pump cover.
Tighten all bolts and the crescent screw finger tight,
ensuring that the pump is flush against the pump cover.
Tighten the bolts and the screw to specification in the order
(A - F), shown in figure 8.44.
22. Install the pump to transmission case gasket onto the case.
23. Fit the ‘O’ ring to the pump cover outer diameter.Figure 8.44 - Pump Bolt Tightening Sequence

25. Check that the transmission end float is set to the tolerance
stated in section 9.2. Refer to figure 8.46. If the unshimmed
end float clearance is greater than specification, shims
are to be placed between the No. 4 bearing and the input
shaft bearing surface. Refer to figure 8.19. If the end float
clearance is less than 0.5 mm then the transmission has
been assembled incorrectly or the parts are out of
specification.
26. Perform the following steps to check the end float :
a. Attach a dial indicator to the front of the transmission
case with the stylus resting on the end of the input
shaft.
b. Apply a force of approximately 250 newtons or 25 kg to
the input shaft.
c. Zero the dial indicator.
d. Place a small lever behind the forward clutch cylinder
and lever the cylinder forward.
e. The measurement recorded on the dial indicator is the
transmission end float or clearance between the No.4
bearing and the converter support tube.
27. On completion of this procedure, adjust the front and rear
bands to specifications detailed in section 8.4.
