    Release Cross-Shaft
    Lubricating

    IMPORTANT: This maintenance operation per-
    tains only to vehicles equipped with mechanical
    (not hydraulic) linkages.

    The clutch release cross-shaft is equipped with two
    grease fittings in the transmission clutch housing.
    See

    25–03 Clutch Hydraulic Fluid

    Level Checking

    WARNING

    2015 Freightliner M2 For Sale

    Use only approved clutch hydraulic fluid (DOT 4
    brake fluid) in the clutch hydraulic system. Do not
    mix different types of brake fluid. The wrong fluid
    will damage the rubber parts of the system, caus-
    ing loss of clutch function and the risk of serious
    personal injury.

    CAUTION

    Do not allow the fluid level in the reservoir to go
    below the MIN line. If too much air enters, the hy-
    draulic system will not operate correctly, and the
    clutch could be damaged.

    If the fluid level is below the MIN line, fill the reser-
    voir with DOT 4 brake fluid until the level reaches the
    MAX line. See

    25–04 Clutch Hydraulic Fluid

    Replace the clutch hydraulic fluid every two years to
    ensure clutch function is reliable and correct. Use the
