  2. Install the 3rd and 4th clutch apply plate (653) into the input housing. Index each leg of the apply plate into the apply ring legs.
    3. NOTE: The correct number of fiber plates must be used to avoid damage to the transmission. An incorrect stack up height can cause either excessive clutch slippage or insufficient release, resulting in burned clutch plates.
    IMPORTANT: The first steel plate (654B) has the same spline configuration as the 3rd and 4th clutch apply plate (653).
    IMPORTANT: The 3rd and 4th clutch plate stack is model specific. Clutch plate stack up could be either 6 or 7 plates.
  3. Install the 3rd and 4th clutch plates starting with a fiber plate assembly (654A) and alternate with a steel plate (654B).
