SsangYong Musso. Manual - part 485

AUTOMATIC TRANSMISSION  5A-117

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.

Valve Bodies

Notice

1. Do not wash the nose of solenoids in solvent.

2. Be aware of ball positions in the upper valve body.

3. Be aware of 1-2 and 3-4 shift valve positions, they can be

swapped.

4. Check the 4-3 sequence valve and spring orientation.

5. Check that the 12 mm ball is in the lower body.

6. Do not mix up the low first blow-off and the torque converter

blow-off ball springs.

7. Check the line pressure relief valve for swarf, and be aware

of replacing the shims.

8. The orifices in the valve body are for stability and safeguard;

do not drill them any larger.

9. When servicing the transmission, ensure that the solenoid

5 damper spring is not broken.

10.  Locate the detent spring central to the detent lever.

To assemble the valve bodies, proceed as follows.

1. Wash the upper and lower valve bodies (refer to figures

8.47 and 8.48) thoroughly with cleansing solvent and blow
dry.

2. Check the valve body cavities, ports and holes for damage

or obstructions.

3. Install the detent lever locating pin.

4. Thoroughly wash all loose components.

5. Check that all valves slide freely in their location.
