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.
