gearbox whining :(

[makaveli]

Hi Guys,

I have noticed that my gearbox whines, it has for some time now although its a little louder. When driving the engine noise covers it although if I put along at very low speeds in either 1,2 or 3rd it whines a bit.

The gearbox oil has always been changed regulary and it still feels nice changing gears.

What could be the problem???

Will i need to get another gearbox in the near future???

thanks

Mark

do u have a solid short shiftter? my box was quiet until i put one in and it started to whine.

[Mr GTS4]

does it do it with the clutch in?

[Oosh]

Are you SURE it's the gearbox? Both mine and RowdyR32's cars suffer from diff whine (his is worse ).

Although ours is only really noticable in 5th gear, when cruising at certain speeds between 80-100 KPH, slow down or speed a couple of kays and it lessens?

Edit:

Oh and i should add, he changed oil, got it serviced (if they did anything), and still it whines... without replacing it, and you might get another whiner, you could have to live with it.

i have a solid short shifter, used to have the wine in mainly first and second, changed tranny oil and its gone

Im not sure if I have a short shifter, when the car is idling the thrust bearing makes a little noise. Although the whining noise is occuring when im driving.

My diff whines a lil like how Oosh said, although the noise im talking about is different.

thanks mark

if it doesn't do it with the clutch in, its most probably your input shaft bearing.

[Jolinator]

im with mr gts4 most people say thrust bearing but its usally the input shaft bearing making the noise, i no my car does it, and its got a brand new clutch, thrust bearing, etc,. its only a very faint whine, that only i notice

[krzysiu]

Yeah it would be the shaft bearing. My line does that too now. It just really depends if you can put up with the noise. If its gets really loud and annoying. Fix it

[makaveli]

thanks for the input guys!!!

if im really light on the throttle and let it rev to 3,000rpm in 1st,2nd or 3rd it gets louder.

If i drive normal the filter and exhaust noise covers it.

How much would it cost to have the bearings changed???

thanks

I think the bearing doesnt cost alot but the labour to do it will, because the bearing is inside the gerabox (correct me if im wrong).

I had a similar noise only when slowing down found out when rebuilding the engine that the crownwheel had nearly .5mm clearance!!
