2001 Towncar Shudders while accelerating


As I accelerate, I feel this shuddering almost as I"m going over rumble strips (2001 TC 57,000 miles), I've heard it could be a torque converter "slipping" as well as fuel injectors, and someone told me my u-joints could be the problem.

The shuddering is pretty "pronounced" but I notice this happens prettymuch only when I'm pressing lightly on the gas. And it's frequently around 35 mph-45mph, but sometimes the shuddering doesn't even happen depending on my acceleration.

Is this my torque converter, or no. I need an air filter but I doubt it could be that..
Please someone let me know what this could be.

Yes, it's a torque convertor shudder. Flush your transmission fluid and add an additive to help shudder (shudder fix, etc). That fixes most of the vehicle, the others will need a convertor. Try to keep transmission serviced around every 30k will help this concern.

Yeah I have the same problem in my 2003 town car, it starts to shudder when I press lightly on the gas. It happens at about 40mph and up. If I push the gas more it usually goes away. Sometimes I notice it more then other times. I replaced the coil packs, but that didnt work, I ran lucas and other fuel injector cleaners and that didnt work, I flushed the tranny still didnt work, I added trans tune by seafoam which cleans out your tranny then I replaced the tranny filter and cleaned the pan after running it for a few hundred miles and that didnt work. Then I tried adding Dr shudder fix which according to alot of people works but that didnt work. Then only thing I didnt do is drain the torque converter but I dont think that will help. I also replaced all the spark plugs. I think I will try trans tune by seafoam again then run it for 500 miles and flush it out again. I really dont want to replace the torque converter but eventually I will have to and by then I would have paid $400 in tranny fluid, additives and other. Oh well you got to try the cheap fix first. Oh the air filter has also been replaced and the oil changed with mobile one. I will say dont just put any oil filter in it though, make sure its motorcraft or any other high flow oil filter.

    I had the exact same problem in my 1994 TC. I went to my local auto repair shop and he told me it was my torque converter and gave me a tube of Dr. Trannys instant shudder fixx, it worked Phenominal!!! no more shudder!!!! i was so happy and it was 6 bucks for the lubricant! cheapest fix! and it was right it did work instantly! hope this helps.

Below is my original answer, which I submitted in good faith, based on years of experience with other automotive issues. Alas, it - and by extension, I - was wrong.

My 2003 Cartier L Town Car developed the shuddering issue about 40,000 miles ago. The solution is Ford's friction modifier for limited-slip differentials (a tiny bottle of liquid), added to the fluid in the transmission.

The person at the Ford parts counter will know which bottle to get; there is an official Ford/Lincoln TSB that advises this method.

BEWARE: The fluid stinks more than you can possibly imagine! Use a cheap funnel that you don't mind throwing away (in a dumpster far from your residence), and add the fluid in a well-ventilated area. Park the car where the funnel will be downwind from you, and add when the wind is blowing 5 to 15 mph.

RESULTS SO FAR: over 40,000 miles with no more shudders, and my overall fuel economy has improved by 2.3 mpg. That's a HUGE increase!

My Original and Incorrect Answer Appears Below:

NO, respecting the foregoing answers. I refer you to http://lincolnforums.com/forums/threads/5331-1999-Town-Car-Transmission-Shudder-or-misfire

Scroll down to the answer provided by member "smak90" on 12-14-2009 at 09:36 AM; the offending part is the DPFE. The link between the specific part and the vibration is somewhat convoluted and technical.

If you've worked on computerized cars,you know that sometimes the cause of a malfunction or other abnormal condition or indication is in a component having no obvious connection with the system in which the malady is observed.

Swapping out parts quickly gets to be ridiculously expensive, and in this case, you could replace driveshaft components (or the entire driveshaft), the torque converters, and the transmission -- and still have the problem, because nothing was wrong with the pieces you took (or had taken) from your car.

Granted, you won't have proof that it's the DPFE until you swap it, but a new one isn't anywhere close to as expensive as either a driveshaft, a torque converter, or a transmission.

Also, don't rely on any sort of pour-in goop to solve this sort of issue: you're only buying future headaches if you do.

My automatic Subaru shudders when accelerating changing through the gears


The first thing to do is have the transmission fluid changed, the shudder is clutch plate shudder in the clutch apply pack. When the fluid gets worn from use the chemicals that prevent this wear out after 1000's of miles. The transmission should have a fluid and filter at least every 60,000 miles, more under severe use like extremely hot climates or heavy loading.

Car shudders on acceleration


I'd check the motor mounts. Shuddering upon acceleration indicates movement of the engine inside the compartment. Best of luck.

It's a step-by-step process. If it only happens on acceleration then it is a drivetrain problem. Start verifying from the outer cv joints and go in from there
