2005 Liberty Limited 4WD/automatic with 189000 mi. Has been working perfectly then suddenly I get a transmission temperature warning and jeep goes into limp mode, so I pull off road to parking area now it won’t shift into any gears. Towed it home and pulled only a P0700 code with my OBD2 code reader, so I pulled transmission pan to check for debris. Trans oil looks great and there’s virtually nothing in the pan after rinsing everything With carb cleaner through a coffee filter, so I’m hoping it’s something simple like a speed sensor or a solenoid pack. Going to take it to a dealer for a full scan next. Anybody have any ideas what this could be?
