Auto or Manual?

If auto, it may be the transmission shudder which is often got by having incorrect or cooked transmission fluid.

[dka113]

yep auto tranz, i checked the transmission oil, it has a redesh brown, more brown color realy, wud that b a sign transmission oil is cooked?

does it smell burnt? it could be the wrong oil also.

id be getting a full trans flush done with the correct oil

[dka113]

na dosnt smell burnt, but getn a full trans flush with correct oil sounds gud,

would you know cost of gettn it done all up and a gud workshop ?

cheers.

all depends on what part of the country you are in.

mitsi on the shore charge about $70 - $80 an hour. the expensive part will be the 10 - 12L of trans fluid

[dka113]

thanks for that, so wud there b any other cause of this vibration that you mite know of besides tha trans oil eg.. diff, drive sharft etc.. ?

cheers

does it do it at high rev's, like 4000rpm and up? Most of the auto trans shuddering problems occur in 4th and 5th gear at 2000-3000rpm.

[dka113]

yeah thats sounds about rite!

[dka113]

mostly @ 2-3k in 4 and 5th gears and the shudderimg is slow feels like one of your tyers has a small bulge on it , yea it will do it @ 4k too sumtimes, but when i accelerate up more frm 4k the shuddering will stop and it has happen at a higher rev than 4k about just over but short and fast lik for about 2 sec ... theres times where no shuddering will take place for a day or two, at times for a week but the fact is it happens,

sound like bands in trans stuffed or transfer case poked to me

[bradc]

yeah it really sounds like the wrong oil is in there. change it for amsoil atf or mitsi SPIII atf oil.

[Subaru ETA]

a mechanic put the wrong oil in my mates vr4 transfer case before he bought it. ended up pretty much melting the internals of it

[dka113]

I dnt wana go there if that was the case, well i will do the atf flush and change and see what happens, before my status becomes worse, thats if it isnt already,

is my issue with tha tranz high priorty like do asap?
shud i be driving my legnum at all?

it drives mint besides tha shudders now and then.

thanks to all.

Do the ATF flush asap. If your problem is gearbox shudder, then it is destroying the clutch packs in the box. If you leave it then there is only one way this is going to end up, and it involves you being out of pocket.

There are other possibles for vibrations, but with brown fluid in the box, you'll be killing it anyway. If the ATF doesn't cure the shudder, then be happy that the box is now being looked after and come back for other ideas! Also, try searching these forums for vibration, vibrations, shudder etc.
