2000 Lincoln Towncar - Feels like going over rumble strips	Sign In

Sporadically feels like I am going over rumble strips. We had a loose lower ball joint and replaced it but it didn't fix the problem. It happens at various speeds from 25 mph to 70 mph. 80,000 miles, new tires and aligned. Was told that it could possible be the transmission. It feels like the vibration is under the drivers seat. Any input would be appreciated.

How long since last tune up? If you have a small engine misfire, it will do the same thing. It is possible that you have what is called torque converter shudder. This can be eliminated by either flushing the transmission fluid and changing the filter. Or, as a stop gap measure, you can buy a can of anti-shudder that will stop the shudders. Just remember the additive is a band-aid fix.

Thank you. I've not had it tuned up because it says 100,000 miles and I have 80,000. Should I take it and have the transmission flushed?

I would do a tune up first. The 100,000 mile claim is ususlly never reached. The plugs will last that long as long as everything else is perfect. We have to tune ours anywhere from 40,000 and up. You may want to have the transmission serviced. Maybe not a complete flush, but a filter and fluid change will not hurt anything.
