Q: How to service and repair Automatic Transmission Shift Levers for the column shift on Mercury Grand Marquis?
A: Service and maintenance procedures for the column shift automatic transmission shift levers must start with back up power supply depletion to stop potential air bag activation before beginning work. Begin servicing or repairing the automatic transmission shift levers for the column shift by disconnecting both primary and secondary power supplies that include the battery ground cable and any supplementary batteries and power supplies. Start the repair by unscrewing the lower steering column opening finish panel before setting aside the parking brake release handle and removing the other panel screw and releasing the retaining clips by pulling outward. The process continues with removal of the five screws fastening the lower steering column opening finish panel reinforcement before you detach all three screws from the lower steering column shroud. Move on to remove the upper steering column shroud then disconnect the transmission control (TC) switch harness connector. The steering column requires separation of the TC switch harness from its locators as well as the automatic transmission shift lever cover from the steering column. The replacement of the old automatic transmission shift lever pin must be discarded permanently and its reinstallation must be avoided. The necessary step for this instruction involves removing both the automatic transmission shift lever pin and the automatic transmission shift lever. Follow up the installation process by executing the reversal steps for removal.
Q: How to Service and Repair Automatic Transmission Shift Levers on the Column on Mercury Marauder?
A: The first step toward servicing or repairing the column shifter automatic transmission shift levers requires the shutdown of back up power sources to stop air bag activation. The process begins by disconnecting the battery ground cable which needs waiting for at least one minute. Additionally, disable any auxiliary batteries and power supplies when present. Start the process by taking off the lower steering column opening finish panel through screw removal then position the parking brake release handle aside before undoing the screw from the panel while pulling outward to free the retaining clips. Before moving on to the next step remove the five screws that fasten both the lower steering column opening finish panel reinforcement and instrument panel reinforcement brace. To side the automatic transmission shift lever indicator cable out you must first loosen its screw and disconnect the cable from its position. To remove the ignition switch lock cylinder position the key to RUN and press the lock cylinder release pin while pulling the cylinder out. Low steering column shrouds need to be taken down through unhinging four screws before the column falls after unfastening four nuts. The next step requires separation of both Transmission Control Switch (TCS) harness from locators and gearshift lever cover from steering column after upper steering column shroud removal. The gearshift lever requires both removal of its old pin and the subsequent removal of the gearshift lever. The completion of the installation requires following the steps in reverse order with which you removed the parts.
Q: How to Maintain and Fix Automatic Transmission Shift Levers and What Steps Are Involved for a Mercury Mariner?
A: The service and repair of automatic transmission shift levers begins with the vehicle in NEUTRAL position on a hoist. Gently lever up to remove the top finish panel followed by the upper shift lever trim ring after placing the floor shift selector lever into (D) position. The shift cable requires removal from the gearshift assembly through two steps: first detach the shift cable end from the gearshift lever and then separate the shift cable from the bracket. The procedure to remove the shifter starts by disconnecting its electrical connector and after that unscrewing all 4 bolts to complete the removal. The first step for installation is to mount the shifter assembly using the 4 bolts and tighten them to 25 Nm (18 ft. lbs.) then reconnect the electrical connector. The installation process starts with the upper center console followed by the upper shift lever trim ring where proper orientation of the thick tab on the driver side front of the shifter should be checked before assembly. Conclude the process by readjusting the shift cable if required.
