4T65E with P1811 code.
 
About a year ago I purchased a 2002 Buick Regal LS with 89,+++ actual miles. Shortly after I brought the car in for an engine oil/filter change. The mechanic told me that the transmission oil was very dark and should be serviced. So I had the transmission pan dropped and installed a new transmission filter and added Dextron 3 to the proper level. The transmission shifted smoothly until the ATF got up to operating temperature and the harsh upshifting started. I then brought it to a transmission shop and I was told it had a P1811 code which would indicate a faulty Pressure Control Solenoid of which I was told was a weak part in the 4T65E transmission. My question is should I replace it with a AC/Delco #10478146 PCS, or is there a better quality pressure control solenoid manufacturer I should consider using instead. Thank you.
