Hi There,

I just bought Toyota corolla seca 1995 auto (timing belt has been
replaced already on 148000). it has done 178000. it is running smooth
except, when pull the accelerator like on 1-2nd gear (auto gear i
assume) a strange sound appears for about 1-3 seconds. I have also
noticed the sound when you are inclining (going up) on a road or pull
the accelerator harder to get good speed. sound stay 1-2 sec some time
3-5 sec

Sound: looks to me like some metal parts are in the friction. Sound
appears from the bottom part of the car

I would really appreciate if some one please help me out with this
situation.

cheers

As Ray will say, "Sounds are very hard to diagnose without hearing them..."

And they are. Can you decribe it more? Is it a rasping, a rattling, a
grinding, a 'shearing', etc?

I have a Subaru with AWD, and the best way to describe how it sounds is
like a rattlesnake! It's one of the gears in the transfer case that wears
down.

Here's what I do for that: I put in something called SeaFoam for
transmissions. HOWEVER, I know what that sound is, and know that although
not a real good 'fix', the SeaFoam will keep it from getting worse.

In your case, see if you can tell us better the sound, and then see if
someone is familiar with it...

Hi There,

Thanks for the quick reply. the sound i can describe is like
"ggggggggggggggzzzzzzzzzz" or "zzzzzzzzzzzzzzzzzzzzzrrrrrrrr"came only
for 1-2 seconds and appears when you pull the accelerator a bit
harder. usually on 1-2nd gear.

Thanks for all your help!

cheers
Faraz

Perhaps Ray can help with this one.

The only time I have experienced this type of sound was with a couple of
Chrysler mini-vans I have had here in the US, and what that is is the
solenoids that control the transmission.

I have two cars with ATs, one is a Toyota, and it has solenoids, but they
don't make this noise. Interesting, because Chrysler often uses Aisin
transmissions, just like Toyota (at least in the Jeeps, anyway)

Is there any kind of slippage or hesitation when this happens? Also, when
was the last time a tranny serive was done (Filter and fresh ATF)? Have a
look at the dipstick; is the fluid brown (or Black?!) and does it smell
burnt?

Yup, sounds are difficult to diagnose without hearing them first hand. The
OP mentioned that the sounds occur when the transmission is getting ready to
shift, which implies that it occurs at higher engine RPM. Check the heat
shields around the exhaust manifold, catalytic converter, and underbody to
make sure none are loose or resonating. If it is resonating, give the
shield a rap with a hammer to put small dents in it.

Rev the engine while in neutral or park and see if the noise occurs. If it
does, then it is unlikely to be the transmission or drivetrain. Check
accessory drive belt tension and check the timing belt tension. A bad
tensioner or improperly tensioned timing belt can cause engine noise. Check
power steering fluid level and see if you notice any unusual movement of the
alternator pulley. Check for coolant leaks under the front of the engine
near the timing cover and check the coolant level. If there are coolant
leaks, check the water pump.

Hi Everyone,

The problem has been diagnosed. It is the exhaust that is making noise
on the bottom of the car. when the RPM goes up while driving or load
on the engine, it give you a sound "zzzzzzzzzz or ghrrrrrrrrrrr". I
will ask mechanic to fix it.

thanks for all your help and kind suggestions.

Thanks!

Faraz,

Thank you for the update. It sounds like my first guess, an exhaust heat
shield, is making the noise.

Forogot about those! Never really had a Toyota that had that problem. Did
have a Honda (Had One Never Did Again...) and they were notorious for
loose heat shields! My Service Manager's advice? "Remove the heat shield..."

The problem with removing heat shields is that whatever was being shielded
from the heat tends to get burned.

A few taps with a hammer usually solves buzzing heat shields.
