Will the gear shift knob be steady as a rock when driving on rough roads ? Will a person be able to see it move when in gear ( any gear ) travelling at speed ? Does the rear tranny mount allow the transmission to move a tad ? Could this be transmitted up to the shifter through the linkage ? Lastly, to clarify, before I installed the new rear tranny mount I never saw the shifter wiggle side to side. Now after the new mount and new shifter bushings the gearshift moves side to side when I hit fairly large bumps in the road. Should I have it checked on the lift ?
