• Erratic line pressure
  • Low line pressure
  • High line pressure


Load conditions and pin wear can reduce available output and lower line pressure, resulting in reduced shift and engagement quality when hot.


Replace OE pin with correct style Sonnax pin.


A grooved version, 84881A, for 4T60-E and 4T65-E units without the brass orifice plug also is available. The correct style pin must be used or line pressure and pump performance will be adversely affected.
