21. Remove dial indicator, dial indicator extension rod and gauge bar. Install No. 15 thrust bearing.





22. Check end clearance for selective fit of No. 16 thrust race. Mount Dial Indicator with Bracketry 100-002 (TOOL-4201-C) or equivalent with stylus on end of output shaft as shown. Zero dial indicator. Tighten end play tool screw to 4-5 Nm (36-44 in lb). Read dial indicator.





23. Dial indicator reading should be 0.10-0.40 mm (0.004-0.016 inch). If clearance is not within specification, select a thicker or thinner washer from chart below and repeat the clearance check.

NOTE: The beveled retaining ring and rear planet support must be removed to change No. 16 thrust race.

24. After completing clearance check for No. 16 thrust washer and clearance is within specification, remove end play tool and adapter.





25. Install low/intermediate one-way clutch assembly.

NOTE: Make sure No. 15 needle bearing is on rear planet support hub and the black plastic No. 15 thrust washer is in place on top of low/intermediate clutch spring retainer.





26. Install low/intermediate clutch wave spring, low/intermediate clutch pack and low/intermediate clutch pressure plate over the one-way clutch.

NOTE: The friction plate internal splines will center the one-way clutch.





27. Install low/intermediate clutch retaining ring.

CAUTION: Make sure retaining ring is seated in case groove.





28. Apply dry compressed air, regulated to 40 psi, to low/intermediate apply port (located in rear planet support). Make sure the piston strokes. Check for air leaking past the piston seal.





29. Use a feeler gauge to measure the clearance between the clutch pressure plate and the clutch retainer. The clearance should be 1.27-1.90 mm (0.050-0.075 inch).





30. If the clearance is not within specification, select a retaining ring from the chart below. After installing the selective retaining ring, verify the clearance is correct.





31. Install coast band into case and align anchor pin pocket on band with anchor pin in case.





32. Install low-intermediate drum. Rotate counterclockwise to seat the race of low-intermediate drum and sun gear into the low-intermediate one-way clutch.





33. Install park rod abutment and tighten bolts to 27-30 Nm (20-22 ft lb). Make sure park pawl moves freely.

No. 8 Thrust Washer And No. 9 Needle Bearing:

43. Remove No. 8 driven sprocket support thrust washer and No. 9 direct clutch hub thrust bearing from the driven sprocket support.

Installing No. 9 Clutch Hub Needle Bearing:

44. Separate No. 8 thrust washer and No. 9 thrust bearing. Install No. 9 thrust bearing (only) into transaxle over the output shaft as shown with outer lip up.

Installing Gauge Tube:

45. Install Gauge Tube 307-320 (T94P-77001-MH) over output shaft until fully seated into No. 9 thrust bearing. (This is where the No. 8 thrust washer normally sits.)

Reading A:

46. Place Gauge Bar 307-300 (T94P-77000-Q) across transaxle case with round legs of gauge bar resting on chain cover gasket surface. Place Depth Micrometer 303-DO75 (D92P-4201-A) or equivalent on gauge bar and measure down to gauge tube. Do this on both sides of output shaft (180° apart). Add both readings, divide by two to obtain reading A.





47. Use reading A to select the correct No. 8 thrust washer from the chart below.

NOTE: Reading A and Dimension C from this chart will be used in selection of No. 5 thrust washer.

Reading B:

48. Remove depth micrometer, gauge bar and gauge tube. Install gauge bar and depth micrometer as shown. Measure down to the No. 5 thrust washer mating surface of overdrive drum. Take another reading on the other side of the shaft (180° apart). Add both readings, divide by two to obtain reading B. Remove gauge bar, depth micrometer and gauge tube from transaxle case.

49. Subtract Reading A from Reading B, add difference between A and B to Dimension C. Record this as Reading D.

NOTE: Reading A was obtained during No. 8 thrust washer selection. Dimension C is found on No. 8 thrust washer selection chart following the selected No. 8 thrust washer.

Reading B:
-Reading A:
Difference:
+Dimension C:
Reading D:





50. Use Reading D to select the correct No. 5 thrust washer from the chart below.

Installing No.5 Front Support Thrust Washer:

51. Install correct No. 5 thrust washer on driven sprocket support.

NOTE: Use petroleum jelly to hold washer in place for this step.
