Help me figure this out please?

ZiggityZachh · 07-11-2007, 04:46 PM

I drive a 2000 3.8L V6 Stang. I bought it used with 90K and have owned it 15 months now. It has 119K miles now.
The problem is whenever I slow to a stop underneath the car (sounds like it is coming from the gear shifter,(auto tranny)) it sounds like a small jackhammer is banging. It also does this sometimes in the low gears. Sorry, I must confess Im not too savy with repairs. Any ideas???

i might have the same problem.

I got my 2000 3.8l mustang about 14 months ago with 92k miles on it. It has 106k now.

I have the same jackhammer noise, but it only happends when im in drive, but idle (like a stop light or sign.) And when the a/c is on, when i accelerate it does it as well. Comming from the same place.

i hope for both of us its not an expensive problem. If i figure it out before you, ill post back here and try and help you out

I'm not sure, I've never had that happen to me, though I'm only at 55k miles

Cheddarbob · 07-12-2007, 04:15 PM

does it sound like a knock

simbill · 07-13-2007, 10:19 AM

severly warped rotors? bad pads? both?

ZiggityZachh · 07-13-2007, 10:43 AM

nah, the best i can describe it is like a TINY jackhammer
I also notice it happens when i make a right turn above 20 miles per hour

Just throwing this out there but could these be loose transmission mounts and the tranny is vibrating at idle against the floor pan or its mount. when you are driving is would be under torque and twisting the tranny either away from whatever it would be vibration up against or either pushing it firmly against something causing it to not vibrate under power.

Probobly not. But my best shot in the dark.

ZiggityZachh · 07-13-2007, 01:14 PM

sounds like a good guess to me, i mean it sounds logical
thanks for everyone whos put out their opinion
i appreciate it

ya could try to get the car to do it and crawl under it (after chocking the tires, engaging the E-brake, etc.) and see if you can hear it any better.

Just lay on a creeper with some good wheels. Hang on to the crossmember and have a really good friend drive around town while he drags you around under the car.

J/K please dont do that.

I had something like that on my 99, at first i thought it was a cracked header but it turned out to be the exhaust manifold.

If you have already found out what it was... what was it?

My first ford had that noise to it to. It was a 94 Ranger p/u (Splash Model). I had the 4.0L V6 w/ AT and I never did figure it out. But that damn thing kept on driving so I ended up saying Fuggit! LOL
