d. Using a screwdriver, install the snap ring.

21. CHECK PISTON STROKE OF OVERDRIVE BRAKE



a. Place SST and a dial indicator onto the overdrive brake piston.
SST 09350-30020 (09350-06120)




b. Measure the stroke while applying and releasing compressed air (392-785 kPa, 4-8 kg f/cm2, 57-114 psi).

Piston stroke:
Tacoma, 4Runner: 1.32 - 1.62 mm (0.0520 - 0.0638 inch)
Previa, T100: 1.40 - 1.70 mm (0.0551 - 0.0669 inch)
Land Cruiser: 1.75 - 2.05 mm (0.0689 - 0.0807 inch)


If the piston stroke is less than the limit, parts may have been assembled incorrectly, check and reassemble again. If the piston stroke is nonstandard, select another flange.

HINT: There are 7 different thicknesses for the flange.

Flange thickness




22. INSTALL OVERDRIVE PLANETARY GEAR UNIT WITH OVERDRIVE DIRECT CLUTCH AND ONE-WAY CLUTCH

b. Install the overdrive planetary ring gear.





c. Coat the bearing and race with petroleum jelly and install them onto the planetary ring gear.

Bearing and race diameter









d. Coat the race with petroleum jelly and install it onto the planetary gear.

Race diameter










e. Install the overdrive planetary gear with the overdrive direct clutch and one-way clutch.





f. Place SST on the transmission case.
SST 09350-36010 (09350-06090)

g. Using calipers, measure distance between the tops of SST and the clutch drum.

Standard distance: 15.5 - 16.5 mm (0.610 - 0.650 inch)

If the values are non-standard, check for an improper installation.




h. Coat the assembled bearing and race with petroleum jelly and install it onto the O/D direct clutch.

b. Coat a new O-ring with ATF and install it around the pump body.
c. Place the oil pump through the input shaft, and align the bolt holes of the pump body with the transmission case.
d. Hold the input shaft, and lightly press the oil pump body to slide the oil seal rings into the O/D direct clutch drum.

NOTICE: Do not Push on the oil pump strongly, or the oil seal ring will stick to the direct clutch drum.




e. Install the 7 bolts.

Torque: 22 Nm (220 kgf-cm, 16 ft. lbs.)




24. CHECK INPUT SHAFT ROTATION
Make sure the input shaft rotates smoothly.

25. INDIVIDUAL PISTON OPERATION INSPECTION
