Installation
- untie the torque converter and align it with the gearbox. Apply a coat of Molykote BR2 moly grease to the torque converter center ring;
- install the guide bushings in their places and clean the threads of the torque converter mounting posts to the faceplate;
- when installing the gearbox, align the torque converter threaded posts with the holes in the faceplate. Apply Loctite Frenbloc anaerobic sealant to the threads of the new nuts, screw them on and tighten to the specified torque;
- connect the selector cable and adjust it as described below;
- perform the remaining operations in the reverse order of removal;
- Finally, top up the box with the correct amount of fluid of the type prescribed, as described above.
