2007 Ford Taurus Shudders

Post by jlyon40 » Thu Jun 22, 2017 8:15 am

Hi I have a 2007 Taurus with almost 150,000 miles and recently it has started a shudder when I am driving. Not sure what it is but I'll explain exactly what happens. When I take off from stop there is no shudder, however when I am trying to maintain a certain speed like 35, 45, or 55. The car shudders for probably 2 seconds maybe less. I believe it could be the Tourqe Converter, not sure though. I did hit a really big pothole in a parking lot a couple of weeks ago and this started a little after that. Could it be my one of my CV joints got bent. I ordered a tube of Dr. Tranny fix to see if that does anything. I also checked my transmission fluid and it is still pink and clear. My tires do need balanced but if it were the tires they wouldn't do that when maintaining speed. Any input would be much appreciated. Thanks.

A shudder could be caused by many things. An engine misfire, transmission problem, or drivetrain problem. Scan for trouble codes first. I wouldn't just put in shudder fix in the trans as a guess.

If I had to blindly guess I would say you have a bent wheel. How do you know your tires need balancing?

So a bent wheel will only shudder when I am lightly pressing on the gas to maintain my speed?

How do you know your tires need balancing? Start with the basics and don't put in that trans additive yet.

Well I figured they are going to need balanced because when I am driving around 55-60 my steering will has just a little bit of shake to it. Also I don't think it's a bent wheel considering the wheels look good and the shudder only happens when I am going a constant speed and I am just lightly pressing on the gas to maintain that speed.

Did you look at the inside wheel edges for true-ness? CV joints don't get bent. I would check to see if you have an engine misfire. Scan for trouble codes even if the check engine light isn't on. Engine misfires can be similar to what you're describing, they feel like a trans shudder but they're not.

On an F150 not Taurus but read https://www.fordf150.net/forums/viewtopic.php?t=117535 - there are a couple of very informative posts in that thread.

You may have a failing coil. Or something else.

Try driving with overdrive turned off at the same speeds and see if you can make the issue go away with O/D off.

You might want to give more details on your car. When did you buy it, what maintenance has been done, etc.

I purchased my car from my grandmother because she was getting a 2014 Taurus, and I just payed her what she was going to get for trade in. This November will be my second year owning the car. When I got the car from her she gave me a folder that had every receipt of everything that was done to it. Had sparkplugs changed at 130,000 and it had the fluid drained not flushed every 30,000 miles. When I got home last night I checked the wheels on the inside and out and the CV Joints and they all looked good. Then I checked the sparkplugs and they were a little dirty so I cleaned them up a little bit.

After that I took her for a test drive and there was still that little bit of shudder so I decided to put in the Dr. Tranny Shudder Fix along with a fuel injector cleaner and went for another test drive. Not sure if it was the Shudder fix or the Injector cleaner, but my problem seems to be gone. I just drove to work today and there was no shudder at all. Thanks a lot for all your input. Now I just have to get my tires rotated and balanced to get rid of that little wheel shake I get.
