Question about 1998 Lincoln Town Car
I have an ocasional vibration while driving but it stops wen i let off the gas
The transmission in your car is the 4R70W model,and i've rebuilt hundreds of them through the decades,and the vibration you are likely feeling is in the torque convertor.I call it the "washboard effect",or at least that's what it feels like,running over an old timey washboard,and it can also be described as a shuddering sensation,or chattering.Inside the torque convertor is a clutch that engages to eliminate fluid slippage within the convertor,thus making it more efficient,resulting in better fuel mileage.This clutch becomes weak and slips,and that is what is felt.In most cases,the vibration is felt at speeds of 40 mph and higher.Ford and Lincoln dealers have a Technical Service Bulletin (TSB) out about this,and they advise changing the fluid by dropping the pan,and pulling the drain plug in the torque convertor,changing the fluid to a Ford specification fluid,and adding a highly friction modified supplement to the fluid to prevent the washboarding.In most cases,it solves the problem,but in some cases the torque convertor must be replaced.Good luck
