Hey all,
I have a strange noise coming from my auto all of a sudden, kind of like a light grinding noise. It is very hard to explain, but it is only present whilst driving. It seems independent of gear also; it is present whether im in L, 2, D or N, and is only present when driving. The thing is, the box still shifts very well through all the gears, doesn't have a problem with gear selection, etc. I also got a horrid smell when I got out of the car, like someone had set off fireworks.
My fluid has never been changed during my ownership, which is my biggest mistake, however I was informed by my mechanic it didn't need it.
I'm thinking a full flush is in order to see if it disappears, but can anybody put their finger on what it might be?
I used the search function but everyone else seemed to have problems with their transmission shifting, etc, which i dont have

Take to a good auto trans mechanic and get them to listen and diagnose. Not just the local servo mechanic.
Also for your regular mechanic advising not to change the fluid... he either needs his head red or he was meaning don't do it yourself and get it flushed properly by a auto trans guy...maybe.

Definately the box, the sound is coming right from the shifter location. It almost sounds electrical in nature - its not a harsh grinding noise, more like a soft grinding whirr, and it is completely in time with the car rolling.
I thought diff too, but it seems strange that it is almost as if the sound is coming directly through the auto shifter itself. Took it for a drive up the street today and sounds like there is air blowing like crazy from somewhere. Im clueless. I just need to fix and sell this damn thing. I'll try a fluid flush and see where I stand.

Oh, and both the engine mounts and trans mount were replaced less than 5,000kms ago with my 100,000km service, so Ive managed to cancel out a few possibilities. My thoughts re. diff would be if it had blown it would be whiney, or show signs of wear beforehand?
Thanks for the suggestions, my trans oil is BLACK, much to my disappointment, so I'll start there.

Transmission oil should not be black, should be pinkish. I would get that changed asap. Switch off your radio. Make sure it is not some sort of electrical interference your radio is picking up.

Yeah I think the damage has been done unfortunately. I've seen auto trannies here pass for around $150-$200 so it isn't a major concern, what is a concern is finding someone willing to have a courier pick it up and take it to TAS
Soarer is currently radio-less so that definately isn't an issue I will see how I go with a fluid swap, otherwise its onto a new box I guess! If a flush at least lessens the noise I'll know I've found the source of my problem

it cost me around $30 to send an auto g/box from nsw to qld.
and did a rough quote through e-go for me to send a gear box to hobart is $40.06.
e-go cheap as.
might be worth dropping the transmission sump pan and having a look in there for debris and giving that a clean out as well. can't remember if the sump plug is magnetic or not

Damn, you don't happen to have one youre selling then?
I have had horrible experiences with e-go - 2 of. I'm not here to slander companies, but I'll let widespread feedback speak for itself: http://www.productreview.com.au/p/e-go.html
Interparcel are a few bob more expensive and I haven't had a single issue with them. Looks like the cost benefit outweighs any further diagnosis beyond doing a fluid flush Thanks for that!

there's actually quite a bit of effort that goes into swaping the auto boxes. there's alot of tight fiddly work that will turn your hair grey in a day. i refer to the top gear box bolts...the starter motor bolts and so on.
seriously just pay the little bit to give the fluid a bit of a flush out and go from there.

So my mate has an A340E box from his 91 cressida, he advises it should be a straight swap. Mechanically this may be so, but is anybody aware of any inherent differences? And will the ECU be likely to run it the same?

hey Michael.
you will have to fill me in on what happens with yours cos mine is doing the same. happened thismorning. took it straight to an auto box mechanic and the guy took it for a drive cos it was slipping heaps. would barely drive, started shuddering and freaking me out. any way the fella drove it and it didnt play up for him. it went through all the gears fine.but he thinks that if the auto/clutch or tork converter. not sure if its both. may have gotton water in it so now it causes it to slip. i get the same grinding sound aswell. it happened to me last year aswell but had it fixed for about $900 down in brissy. the guys up here in townsville like to rawt us boys in the army and quoted me 3 grand. tossers

Honestly Drew I've given up on the Soarer right now due to lack of time and money, but I'm doing a full fluid flush next weekend. Fluid is a manky colour so I best see how it runs with some fresh stuff. Failing that, its time for a new box.
I still haven't been able to ascertain whether an A340E from a cressida will fit as nobody seems to be able to tell me, so I'll just roll with what I have for the moment and see what happens

A grinding noise can be generated by many things from worn out brake pads to axle bearing failure. Once a grinding sound has been detected action must be prompt. Grinding in most cases is telling you something has failed or is failing....
Since the old thread has been dug up, for the purpose of closure / solution of this problem, I ended up replacing the box and the problem was instantly fixed. My curious mind had me tinker and pull the box apart to find that the bearings were shot, hence the grinding noise travelling directly through the trans tunnel.
I have since sold the Soarer and I have just picked up my Toyota 86, but I'm now looking for a nice v8 - having my Soarer withdrawals already
