1996 Toyota Celica grinding from a stop

HI there,

Does it make any odd noises when you brake or roll to a stop?

mark (mhpautos)

yea just before u come to a complete stop is makes a definite click (single click) around the same time the trans would shift back into first

this may or may not be related: but there is also what woulds like a suspension crack from the front of the car when turning left, going over bumps, and sometimes even breaking

the cracking has always been there and never really caused an issue, this current issue on the other hand has gotten worse than before.

Update today: It seems multiple short trips make it more prone to happen. could it be something to do with temperature change?
The sound itself also seems to happen between 1200-1500rpm

HI there,

The click can be a loose brake pad in the caliper, you see this a lot ,the grinding noise is a bit odd, have you had the brakes fully inspected as yet, the clunk or knock will be a work suspension bush making a noise with the weight transfer under breaking load, have the front end carefully inspected first also the brakes and let me know what you find.

my brakes were inspected about a month ago. recently i had the suspension noise checked and everything was tight, the clicking sound sounds alot like the sound you hear when the exhaust system is cooling down when you turn your car off.

I drove my car today on a long trip and no matter how hard i tries unless i gave it full gas from a stop i couldn't get it to make this grinding sound.

best way to describe this sound is if you had flem in te back of your throat and u pushed your tongue near the top of ur mouth and breathed out thru ur mouth.

also when your not in gear (its an auto) sitting n park if u give it a bit of gas u hear a clunk when you take your foot off the gas

Remove the drive shaft spline split pins and re tighten the nuts, check all engine mounts and haver the front sub frame bolts backed off and re tensioned.

this is to fix both issues?

ive had an ameteur mehanic tell me the grinding is probably the torque converter

This for the click noise, as for the grinding noise, with out hearing it it is very hard to say, i will give it some thought,

some more addition info because he brought up the torque converter thing

If i rev the engine in Neutral there is no sound.

I did a test to check my torque converter suggested to me, and this caused a similar sound.

I held the brake with in gear and hit the throttle quickly (On/Off, i was scared to cause any dmg)

Hi there,

What you did was not quite correct, the torque converter stall test is in gear brakes applied and hold revs for a few seconds, but this should be done by someone who understands what is going on,

should it make that grinding sound though?

There should be no grinding noise at all.

so if i hold the brake and give it a bit of gas and it does that, that is a good indication i have a torque converter problem?

I have also begun to notice another sound that has developed in the past week or so,

another knock/cracking sort of sound that can happen whenever it wants to it seems, although turning right seems to make it happen alot more often than turning left. going over uneven pavement is can also make this sound. or even just taping the brakes and letting off them or rev'ing the engine in park

Front and Rear Motor Mount were replaced when the engine was rebuilt so they have 9,000K on them as well

I am tending to think tat this is a converter problem, but with out actually hearing it i can't be 100% certain. as for the other problem, sounds like a suspension issue as the noise appears to coincide with weight transfer, have the suspension check for worn components.

mark (mhpautos)

is there a proper way to have the converter tested?
if its bad, what sort of debt could i be looking at

The trans will have to be line tested and pressure tested by a qualified trans specialist, there may be other problems as well as the converter, the converter drives the oil pump this will all have to be inspected before any estimate can be considered, and if this noise has resulted in metal being transposed through the transmission, a full re co may be required, but this just can't be known until the trans is inspected first hand, even removing the pan and checking for metal in the filter and in the pan will be a good place to start.

awesome, so i was convinced to buy a car because it had a brand new beating heart, but actualy its a ticking time bomb.

Well when i check my trans oil last time, it was still full and although getting to be that purplish/brown color it was still good, not burnt and certainly no metalic flakes

That was then, this is now, i would be re checking if this was a few 1,000 miles ago.

This would have been when i originally posted this issue, so less than a week ago when I really started to notice this issue. I do city driving but no more than 100 kilometers per week. Thankfully not alot of stop and go traffic

Well i think that you know what to do from here, let me know how you get on.

trans shop told me second gear is on its way out

Well i feel that it is time for a re-co trans, best to get the complete trans done and don't settle for a patch up repair.

thats like 2,000$ isn't it?

would be best if you rang around and got a for quotes on a change over unit including the torque converter, it will not be cheap, bet to get a few quotes and compare priced in your town, as i am in Australia my pricing will be of no value and any on line prices will be the same as yours, ring local and see what you come up with.

problem is finding ppl who i trust, the big names around here seem to have alot of heat from the BBB

AALL TECH
ALL TRANS
AAMCO

are the top 3 transmission shops in my province (bc canada) and all have numerous complains against them

very difficult

AAMCO is a company that a few of the other moderators have suggested to use in there posts, you will always get a few complaints fromr people no matter how hard you try, maybe ask a few workshops which they prefer to use, you may get a better idea as who to go to that way.

I had AALL tech trans take a look at it and they said there is nothing wrong that they can tell, they weren't even able to get it to grind.

But they did say my ATF is purple and that means something is wrong ???
The guy there had all these awards on the wall for best service n shit, but the guy wouldn't tell me anything. He even half ass answered my questions.

I cannot find anything on the web about ATF turning purple

Is the oil purple? maybe there is a wrong oil fitted? all auto oil is red, this is getting stranger by the post, i would get a second opinion on the oil.

mark[/quote:b21e6ef30b]

what he told me was that its either supose to be red or brown. If its purples that means there is suspended aluminum in the oil and it would be a good idea to rip apart the trans the investigate. He quoted me 400$ to "investigate" i think he wanted to grab my cash..

Ive spoken with other mechanics and even my local dealer. No one says what he told me..

Get outa there and go find a new workshop, i feel that this bloke is more interested in his back pocket than your car. dark oil is a sign of transmission slipping, a good trans shop will be able to do a test and report and offer an estimate before any serious work is undertaken, with the trans pulled down then they will be able to do a firm quote, otherwise look for a complete change over trans, you should be able to get a firm supply and fit price for this.

mark (mhpautos)

does a replacement/rebuild generaly come with a rebuilt torque converter as well? or new. Or is that normally an addition cost.

I've been quoted 1800$ For a complete overhaul

I've been told I should contact people who only use OEM replacement kits and Toyota ATF as the aftermarket stuff isn't nearly as well produced. Price of a trans online from toyota is 2800$ + 1000$ core

The transmission should come with a converter, it will be part of the package, my transmission builder uses after market with out any problems, but then there are different quality after market as well, you get what you pay for in this industry, quality costs, so a cheap price is not always a bargain.
