    Important:  When installing bolts throughout this procedure, be sure to use the correct bolt size and length in the correct location as specified.

  5. Do not install the transmission fluid indicator stop bracket and bolt at this time.

    Install but do not tighten the control valve body bolts which retain only the valve body directly.

    Each numbered bolt location corresponds to a specific bolt size and length, as indicated by the following:

    • M6 X 1.0 X 65.0 (1)
    • M6 X 1.0 X 54.4 (2)
    • M6 X 1.0 X 47.5 (3)
    • M6 X 1.0 X 35.0 (4)
    • M8 X 1.0 X 20.0 (5)
    • M6 X 1.0 X 12.0 (6)
    • M6 X 1.0 X 18.0 (7)

    NOTE: Refer to FASTENER NOTICE in Cautions and Notices.
    NOTE: Torque valve body bolts in a spiral pattern starting from the center. If the bolts are torqued at random, valve bores may be distorted and inhibit valve operation.
  10. Tighten the control valve body bolts in a spiral pattern starting from the center, as indicated by the arrows.

    Tighten 

    Tighten the control valve body bolts (in sequence) to 11 N.m (97 lb in).
