Q: How to replace the shift cable on Lincoln MKX?
A: To replace the shift cable, first ensure the engine has cooled down for several hours if the vehicle was recently driven, then disconnect both battery cables and wait two minutes. Remove the air filter housing, and for V6 models, disconnect the intake duct from the throttle body. Next, remove the battery and battery tray. For 2018 and earlier Edge models and 2015 and earlier MKX models, detach the shift cable from the shift lever and console, then remove the center console; for 2016 and later MKX models, remove the right-side inner splash shield and disconnect the shift lever cable from the TRCM lever. Disconnect the cable from the shift assembly on the floor, remove insulation from the floor area under the instrument panel to access the fasteners securing the cable grommet, and then disconnect the shift cable at the transaxle control lever by popping the cable end off the lever ballstud. Detach the cable housing from the mounting bracket on the transaxle, disconnect any cable retainers along the cable length, and remove the grommet plate nuts from the floorpan studs. For 2018 and earlier Edge models and 2015 and earlier MKX, pull the shift cable through the floor, passing it under the air duct leading to the rear seats. Installation is the reverse of removal, ensuring to adjust the new cable afterward. If replacing the TRCM on 2016 and later MKX models, initiate "Default-to-Park" before removal, which involves turning the key to the On position, opening the driver's door, shifting into Reverse, disconnecting the electrical connector from the TRCM, and waiting for the system to initiate. Disconnect the shift lever cable from the TRCM lever, remove the selector lever cable retaining clip bolt, release the tab to detach the selector lever cable from its bracket, and remove the TRCM mounting bolts. For the transmission park cable on 2019 Edge models, disconnect the negative battery terminal, remove the battery and tray, set the parking brake, and remove the engine cover. Locate the Park cable shift lever on the transaxle, unclip the cable, and remove it. Inside the vehicle, locate the manual release cable housing bracket, remove the mounting nuts, detach the cable grommet, and remove the cable assembly through the firewall. For adjustment on 2018 and earlier Edge models and 2015 and earlier MKX models, set the parking brake, disconnect the negative battery terminal, remove the air filter housing, place the shifter in Drive, and remove the cable eye from the control arm. Manually move the shift arm at the transaxle, rotate the lever as specified, and remove the TCM electrical connector and bracket fasteners if applicable. Carefully pry the adjuster lock tabs out, align the cable with the control lever, connect the cable end back onto the manual lever ballstud, lock the adjuster, and ensure the cable is securely seated. After installing any remaining components, apply the parking brake, start the engine, and shift through each range to verify the adjustment.
