If these cannot be read or are on the head, the transmission code letters can also be read under the left subframe mount bracket.

To read the transmission code letters under the console directly from the transmission, the engine and transmission must be supported. The left subframe mount bracket -A- must be removed. 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 .
