Pinpoint Test C : SELECTSHIFT™ (8F35 Transmission)

  1. Refer to Transmission Controls - 6F35 for schematic and connector information.

    Normal Operation and Fault Conditions 

    The SelectShift™ switch is a toggle switch integral to the selector lever knob. When the selector lever is placed in the M position, the upshift/downshift feature becomes activated. If a new switch is required install a new selector lever knob.

    Possible Sources 

    • Connectors damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals
    • SelectShift™ switch
    • 1.5L TCM
    • 2.0L PCM

  2. C1 CHECK THE SELECTSHIFT™ CIRCUITS FOR AN OPEN

    • Ignition OFF.

    • Disconnect For vehicles equipped with the 1.5L, TCM C1750.

    • Disconnect For vehicles equipped with the 2.0L, PCM C1915B.

    • Disconnect Selector Lever C2096.

    • Inspect for damaged or pushed-out terminals.

    • Measure:

      For the 1.5L
