Shift Solenoid B Performance or Stuck Off/
2-3 Shift Solenoid Valve Performance
This could happen because the solenoid is bad or it can also happen if the 3-4 clutch is bad . Another possible reason is with a high stall over 3000 normally the PCM becomes confused and does not thing the shift has actually taken place.

Thanks Performabuilt, great article. The car has a 3800 Vigilante stall, I put H/C package on this winter. The car ran fine after H/C package, car shifted fine. After I took it to get it tuned thats when the 2-3 shift started acting up. My tuner thinks its the 2-3 shift solenoid. I am thinking about replacing the solenoid myself. What all is involved, after I pull the pan can I see the solenoid? Thanks Again George

Its realy simple there are thee side by side A and B the have clips holding them in , One will feel like its just loose kinda floppy this is the B solenoid The A solenoid will have some spring presure behind it, Generally I suggest changing them as a pair
