Likely causes

  1. 1

    Low or degraded transmission fluid— Most likely

    Check the fluid level and condition. MF Dyna-VT and DynaShift units are sensitive to fluid condition — dark or burnt-smelling fluid should be changed.

  2. 2

    Faulty transmission solenoid valve— Possible

    Each gear/range selection uses a solenoid-controlled valve. If one solenoid fails, that gear or range becomes unavailable. Diagnostic software pinpoints the failed solenoid.

  3. 3

    Transmission control unit (TCU) fault— Possible

    The TCU can develop faults, especially if the machine has had voltage spikes. Check for related ECU codes.
