    At what speed is it occurring? If you ruled out a tire problem such as an out of balance or out of round tire i would start by checking both u-joints in the front and rear driveshaft.

Why it my lye in the torque converter I would not expect this, I'd start else where first. My first call would be a universal joint at the drive shaft.
You'll need to climb underneath (engine off and E-brake on and inspect this) look for looseness with in the driveshaft. This could be withinin a tire too, perhaps a bulge in a rear tire or thrown weight giving you issues
I hope this may have helped,
Tom

I have a 2001 gallant es and when am in drive and am stopped at a red light it states to vibrate but when am driving it stops, When I drop it in neutral it stops I've done a tune but it didn't fix it


might be your engine idle is low and is slowed even more by the torque convertor when stationary. In neutra there is no drag on the torque convertor and idle is allowed to stay faster hence no vibration

Transmission issues


turning or putting "strain" on the steering WILL NOT have any effect or damage to the torque convertor. However, sitting stationary for log periods of time with the vehicle in gear can cause damge on the torque convertor over time.

What does it mean when they say the torch convertor is stuck open on my grand prix?


I think you mean torque convertor, and I have not heard that term "stuck open". I think some one is trying to make some money from you. What is your car doing that makes you think it is the torque convertor?

MY MOM HAS A 2002 MALIBU. HER SMOG CHECK DIDN'T PASS. 1ST PROBLEM "TORQUE CONVERTOR CLUTCH CIRCUIT PERFORMANCE OR STUCK OFF". 2ND, " CATALYC SYSTEM EFFICIENCY BELOW RESULT BANK 1". NOTHING COMES BACK WHEN...


i dont think so!! first of all, tcc is mounted on tranny, and eficiency below result bank 1. sounds like a bad 02 sensor, try changing front sensor,go to any auto parts store and buy a haynes manual for your model and year. they are based on a complete tear down of car. for about 20.00, if ya cannot find tcc ask auto parts store,

Vibration in 1998 town car


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
