Lincoln MKZ unable to shift into park, only drives or neutral on Lincoln MKZ

Some Lincoln MKZ owners report experiencing difficulties shifting into park, with the vehicle only able to drive or go into neutral. This issue may stem from problems related to the transmission or the shift lock control ECU/solenoid. Additionally, misaligned throttle position sensors, malfunctioning shift solenoids, or general wear and tear from higher mileage could contribute to gear shifting problems. Some owners also notice jerking when shifting from park to reverse and delays in gear changes, which may indicate issues with the shift solenoids or the valve body. Furthermore, a failing brake light switch, part of the shift interlock system, can lead to these shifting difficulties, but replacing the switch may resolve the issue. It is recommended that owners have their vehicle inspected by a qualified mechanic to diagnose and address these concerns for safe operation of the Lincoln MKZ.
