If these cannot be read, the transmission code letters can also be read under the transmission mount bracket.

Lower the engine/transmission just enough until it is possible to slide the bracket toward the rear. If lowered further, the pendulum support could be damaged. After being assembled, the selector lever cable must be adjusted. Refer to SELECTOR LEVER CABLE, ADJUSTING .
