2010 Grand Caravan SXT, 3.8L, 175K I had my check engine light come on along with my van going into limp home. When I ran the codes, I pulled a P0765 Shift Solenoid 'D' Malfunction. I replaced the shift solenoid, reset the codes, and took it for a test drive. It worked for a few miles and then went back to the error. I then replaced the entire shift solenoid assembly, which included another new solenoid. After resetting the codes, I took it for another test drive. It worked quite well for about 6 or 7 miles and then went weird. It became very sluggish and not wanting to accelerate. When I shift into reverse, it doesn't want to go with revving the engine to a very high RPM, and then it will only move very, very slowly. When I ran the codes after parking it, I pulled P0869 Transmission Fluid Pressure High. Any help with figuring out this would be appreciated. It's it something I did? And if so, is it something I can fix? Or is it just done?
