7. Transmission Housing Installation

Shaft Assemblies and Housing Installation

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

1. Install the reverse idler gear in the transmission housing.
2. Assemble the mainshaft sub-assembly and countershaft sub-assembly.
3. Install the differential assembly in the torque converter housing.





4. Install the mainshaft sub-assembly (A) and countershaft sub-assembly (B) together in the torque converter housing.





5. Turn the shift fork shaft (A) so the large chamfered hole is facing the fork bolt hole. Then install the shift fork (B) and reverse selector together on the shift fork shaft and countershaft. Secure the shift fork to the shift fork shaft with the lock bolt (C) and a new lock washer (D), then bend the lock washer against the bolt head.
6. Install the countershaft reverse gear, needle bearing, and countershaft reverse gear collar on the countershaft.





7. Align the spring pin (A) on the control shaft (B) with the transmission housing groove (C) by turning the control shaft.

NOTE: Be careful not to squeeze the end of the control shaft tips together when turning the shaft. If the tips are squeezed together it will cause a faulty signal or position due to the play between the control shaft and the switch.

8. Install the three dowel pins and a new gasket on the torque converter housing.
9. Place the transmission housing on the torque converter housing. Do not install the mainshaft speed sensor before installing the transmission housing on the torque converter housing.





10. Install the housing bolts along with the transmission hanger (A) and connector bracket (B), tighten the bolts in two or more steps in the sequence shown to 44 Nm (4.5 kgf-cm, 33 ft. lbs.).
11. Install the mainshaft speed sensor with sensor washer.

NOTE: The mainshaft speed sensor washer is equipped on SLXA automatic transmission; the BMXA transmission does not have it.
