vibration found

redrider · 01-17-2001, 08:17 PM

I hve been to hell and back with my vibrating shifter above 70. I finally found the culprit.. the wrong flywheel!! It seems when I had my rear main seal replaced the shop must have replaced the flywheel with the wron ounce weight. I still have a very little vibration at about 80 but it not the shifter.

Yeah....XLR8R's right. Don't get TOO pissy though. I'm not a mechanic (yet) so I can see if you're working on a bunch of cars at once it'd be easy to get confused. BUT you're paying them to do the job right and at the least you should expect them to pay for the new flywheel and whatever costs you incured installing it. That could've done some real damage if it'd stayed in there for a while.
