How do I change the pressure control solenoid on my 2003 Pontiac Bonneville v6 3800

The oil pressure sending unit is located behind the oil filter, Threaded into an aluminunm housing. It has wiring that plugs into the sending unit. The oil filter has to be removed and you will need a deep well socket and a 6 inch extension. Change the oil and the sending unit together.

You need to take it to a reputable repair facility. The pressure control solenoid needs to be checked for proper operation. If the solenoid is operating properly, the PCM (Powertrain Control Module[computer]) will need to be replaced. If you continue to drive the vehicle with this condition the transmission will eventually destroy itself.

There is a TSB (Technical Service Bulletin) for this problem, consult GM for more info. It simply regards the wiper module cover assembly that has been problem atic in most gm vehicles. Your best bet though would be to remove the cover and look for any signs of moisture intrusion, or broken circuts. If you find a broken circut and are handy with a solidering iron, you may be able to fix this problem. If there is any evidence of moisture, you may want to try to dry the unit out and see if that makes any difference. Normally though this problem ends in replacinjg the complete wiper module cover assembly. Here is where that item is located.

SOURCE: How do you replace the pressure control solenoid

The pressure control solenoid is inside the transmission under the pan on the drivers side. To replace it you will need a lift and a trans jack. It is really hard to do on the ground because you have to remove the sub-frame from the car. If you are not familiar with trans components and removal you may be better off taking it to a shop. You can do more harm than good. Good Luck

This is most likely due to a bad solenoid pack in transmission. You could have tranny serviced and see if it helps. Poor fluid condition makes valves stick in those.
