Jeep Commander solenoid pack failure causing transmission to be stuck in 4th gear after P73 recall on Jeep Commander

Some Jeep Commander owners report experiencing solenoid pack failure after the P73 recall, which causes the transmission to become stuck in 4th gear, rendering the vehicle undrivable. Symptoms of this issue include the transmission being locked in a single gear and the vehicle's RPM climbing without shifting. The solenoid pack is a vital component for gear shifting, and its malfunction can prevent proper transmission function. Additionally, some drivers have noted problems with the shift linkage and dashboard display even after replacing the solenoid block. In instances where the transmission is stuck in 4th gear, turning the vehicle off and back on may temporarily alleviate the issue, allowing for proper shifting. It is recommended that owners have the solenoid pack inspected and replaced by a qualified mechanic to ensure the transmission operates correctly.
