Symptoms:

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

Cause:

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

Correction:

Replace OE pin with correct style Sonnax pin.

Warning:

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.
