NOTE: Refer to the Exploded view as needed during the following procedure.

1. Make sure that the ATF magnet is clean and installed in the torque converter housing. Clean and install the ATF magnet, if necessary.

2. Install the main separator plate and the two dowel pins on the torque converter housing. Then install the ATF pump drive gear (A), the driven gear (B), and the ATF pump driven gear shaft (C). Install the ATF pump driven gear with its grooved and chamfered side facing down.





3. Install the torque converter check valve spring and the valve in the torque converter housing.

4. Install the main valve body (seven 6 mm bolts and three 8 mm bolts). Make sure the ATF pump drive gear (A) rotates smoothly in the normal operating direction, and the ATF pump driven gear shaft (B) moves smoothly in the axial and normal operating direction.





5. If the ATF pump drive gear and the ATF pump driven gear shaft do not move smoothly, loosen the main valve body bolts. Realign the ATF pump driven gear shaft, and retighten the bolts to the specified torques, then recheck. Failure to align the ATF pump driven gear shaft correctly will result in a seized ATF pump drive gear or the ATF pump driven gear shaft.

34. Wrap a screwdriver tip with tape to prevent damaging the reverse idler gear teeth. Engage the reverse idler gear with the reverse gears by rotating the idler gear using a screwdriver.






35. While expanding the snap ring of the countershaft bearing using snap ring pliers, install the transmission housing onto the bearing part-way. Then release the snap ring pliers, and push down on the transmission housing until it bottoms out and the snap ring snaps into place in the transmission housing snap ring groove.






36. Install the transmission housing mounting bolts (23 bolts) along with the transmission hanger (A), and tighten the bolts in at least two steps in a crisscross pattern to 44 Nm (4.5 kg-m, 33 lb-ft).
