I own a 96' thunderbird as well as a 99 taurus and both seem to be having issues at the moment but my T-bird has been making a very weird noise when the transmission is under strain (up hills, or fast acceleration) It almost sounds like a metal vibration, and feels like it's coming from the front end.
I have had many "suggestions" as to what it could be and have sank alot of money into those duggestions, but never ends up being the right thing...anybody heard of such a noise?? [:-]
BTW we checked the motor mounts and all vacuum lines...I'm hoping this isn't a tranny problem..I LOVE this car (although we are in the midst of selling it) but I cannot fit my 2 kids in the back seat comfortably anymore
thanx!

96 Thunderbird Specs:
automatic 116,XXX miles
3.8 V8

 

First, I'd check the cover on the catalytic converter. They are known to work loose and vibrate like that. Then I'd maybe look at the transmission - check the fluid and see if it's a reddish (OK) or brownish (bad- burnt) color.

 

If you have high miles it may not hurt to have the transmission fluid and filter changed also.

 

My local mechnic said it sounds like (he drove it) a worn valve guide...are those expensive??
he wouldn't wuote me a price.
