Symptoms:

  • Erratic 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 solid version, 84881, for 4T60 and 4T60-E units with the brass orifice plug also is available. The correct style pin must be used or line pressure and pump performance will be adversely affected.
