Mercury Grand Marquis Adjust Throttle Valve Cable at your home or office.

How important is this service?

The transmission is what is used to switch gears so that your vehicle runs smoothly and optimally. A key part of this system is the throttle lever, which keeps the shift feel and transmission line pressure in balance at all times. The throttle lever is controlled by the throttle valve cable. One of the key roles that the throttle lever and throttle valve cable play is that they’re responsible for downshifting your vehicle when it is going uphill. The throttle valve cable helps the engine find the right gear to maximize torque. When the throttle valve cable is not properly adjusted, a key component of the transmission is lost. Since the transmission is such a finely tuned machine, an unadjusted throttle valve cable can result in severe damage to the transmission.
