I have a 2006 Chrysler Pacifica that we recently changed the shift solenoid

Hello, your transmission and engine performance needs to be checked to find out what is happening. There's no guess to be made here. Changing the shift solenoid -- what was the action that drove that repair? What did you check and find out? Were you following a "code" alone? What testing was performed? A good diagnostic tool can monitor transmission commands and output. It's really important to do that so that you know what is going on and why. www.repairpal.com/repair-shops
