NOTE:
The bolt holes are offset and the drive sprocket can only be aligned one way.
NOTE:
The retaining ring must be correctly installed.
CAUTION:
If the support is not visible on the inside diameter of the retaining ring, the low/intermediate piston could be damaged.
NOTE:
The dial indicator extension rod must set on the No. 15 bearing surface.
NOTE:
Make sure the No. 15 needle bearing is on the rear planet support hub and the black plastic No. 15 thrust washer is in place on top of the low/intermediate clutch spring retainer.
NOTE:
The beveled retaining ring and the rear planet support must be removed to change the No. 16 thrust race.
NOTE:
The friction plate internal splines will center the one-way clutch.
CAUTION:
Make sure that the retaining ring is seated in the case groove.
WARNING:
To prevent injury, wear eye protection when using pressurized air.
NOTE:
Be sure the pressurized air is dry and regulated at 276 kPa (40 psi).
NOTE:
The foot of the overdrive retainer fits against the band.
NOTE:
Reading A and Dimension C from the chart will be used in the selection of the No. 5 thrust washer.
NOTE:
Reading A was obtained during No. 8 thrust washer selection. Dimension C is found on the No. 8 thrust washer selection chart.
NOTE:
Use petroleum jelly to hold the No. 5 thrust washer in place.
CAUTION:
The No. 9 direct hub needle bearing may still be inside the transaxle from the No. 8 driven sprocket support thrust washer selection procedure. Use petroleum jelly to hold bearing and washer in place.
NOTE:
All the fluid supply tubes must have new O-rings installed.
NOTE:
The manual control valve detent lever must be installed with the shoulder and roll pin hole pointing toward the driven sprocket support.
NOTE:
Prior to installing the roll pins be sure that the manual control valve detent lever shoulder and roll pin hole is pointing toward the driven sprocket support.
NOTE:
Apply petroleum jelly to the drive sprocket thrust washer and driven sprocket thrust washer to hold them in place.
CAUTION:
Be careful not to damage or bend the exciter tabs on the driven sprocket speed sensor wheel. The TSS sensor will not operate correctly if the tabs are bent.
NOTE:
Lower the assembly into the sprocket supports simultaneously.
NOTE:
Make sure that the alignment pins are installed in the case.
CAUTION:
Be extremely careful not to damage the cast iron sealing ring.
NOTE:
After installing the chain cover the input shaft should have some end play and should rotate freely. Apply gentle downward pressure on the chain cover to overcome spring pressure.
CAUTION:
The test spring from the overdrive servo rod tool is plain in color and has a shorter free height than the operational spring. Extreme care must be used not to assemble the transaxle using the test spring.
CAUTION:
Do not assemble the transaxle using the test spring.
WARNING:
Wear safety glasses while carrying out this procedure to prevent personal injury.
NOTE:
When applying regulated 276 kPa (40 psi) air pressure to the appropriate passage, a dull thud should be heard when the clutch or band applies. There should be no hissing sound when the clutch or band applies.
NOTE:
Plugging the vent hole during the test will provide an inaccurate result.
CAUTION:
The seals must be lapped correctly or internal leakage will occur.
CAUTION:
Do not use the bolts to draw pump assembly and main control valve body onto the chain cover case. Component damage may occur.
NOTE:
The transaxle side cover gasket is reusable if not torn or ripped.
NOTE:
The gasket is reusable if not damaged or torn.
NOTE:
Locate and align the orange dot adjacent to the stud on the torque converter and place it in the 6 o'clock position.
NOTE:
Locate and align the orange dot adjacent to the stud on the torque converter and place it in the 6 o'clock position.
