2008 hatch wrx sti questioning a whine?
Hi all recently purchased 2008reg WRX STi 40k miles. i noticed a whine in 1st and 2nd gear i was told this was exaggerated by the bits fitted it goes into gear perfect and drives as it should so wasn't worried at the time! but its got me asking the question so suppose i am left wondering is it a problem!!?
It has Kartboy short shift kit, Kartboy front and rear shifter stay bushes
Whiteline rear diff Inserts fitted.
So anyone tell me if this is at all normal.
Thanks
J

does is sound like its in reverse?
my 2001 bug sounds like its got straight cut first and second gears, but its ok in the rest.
i changed the gearbox oil to the uncle scottys cocktail not long after buying the car in march.
it made no difference what-so-ever to the noise!
ive got used to it now, it drives mint, shifts mint so until something breaks ill leave it...
i have no other mods to the transmission

yeah its a similar sound to driving in reverse! only 1st 2nd so nothing thats been added will effect the sound? it drives perfect just the noise that made me wonder maybe i was a bit naive!!
If its the synchro whats the procedure? il be taking to barrettes motorsport in Canterbury to get checked.
Cheers

excuse my ignorance tommy, im certainly no transmission expert!
if it were a synchro, would it not crunch when changing gear etc? ie going into first and second? even before i done the USC it was fine for putting into gear.
i can get mine into first while rolling at circa 15-20 mph
i was thinking its more a bearing issue, or chipped teeth on 1st and second?

Not sure where that comes from. That was the price for a 5 speeder a while back, they're cheaper now, but a 6 speed is going to be more like £2500.00 + VAT exchange as they are expensive to repair.
Synchros don't / can't whine.
I reckon that the add-ons are the problem, transmittiing the inherent noise into the frame. Throw all that crap off, it does nothing anyway and put it back to standard. Then someone [ we can ] evaluate what might or might not be wrong.
All transmissions make a noise, it is unavoidable due to what is going on inside. Rubber bushes are there to insulate the car from the noises, sometimes more effectively than others - but hard bushes and direct type quickshifts ruin the insulation and you get noise transfer.
But don't assume that's what it is, because if there is something adrift, a stitch in time might save a bigger bill. Generally, 6 speeders are bulletproof and quiet. Sadly the drivers/owners are not.
If we can help and you are near enough pop in for an opinion and a road test It costs nowt.
Good Luck no matter what, David APi

The early hatch boxes are known for noises, this is due to the design of the baulk rings in the box, you'll probably notice on first start in a morning it will sound awefull bit like a gratey noise, Nothing to be immediately concerned about. but if it's really causing you serious issues they did modify the part, but being honest we've never fitted one yet, also the hatch box doesn't run an oil pump either, it's all splash fed with gallery's and guides..
BTW 40k is due an oil change on the box incase you've not changed it yet 75W90

on the flip side, mine has no modifications at all, but has had a replacement engine from API before i bought it.
but i severely doubt changing the engine would have any effect on the transmission.
if i get chance ill try and arrange at some point for API to have a look, but i know thats going to end up costing me a lot of money lol.

Being a transmission expert, I am really interested to know how a synchro ring can cause a whine. They are trapped on the sprags of the synchro hubs and run an oil film between the mating face of the ring and the taper on the gear. Which is the only rotating situation where a noise might occur BUT there is almost no contact with anything that might cause a whine, so that is an interesting theory that they can whine.
The carbon coating on the rings from 08 hatch on is to improve synchromesh as the earlier non coated rings had a short shelf life. and started crunching well within warranty.....
Chuck away all the "improvements " I think you'll find that'll fix it.

I popped into Torque Developments today in lakeside went in to ask about a service I mention the gearbox whine I have he said "oh that will be your synco" he didn't go in
The car just said what he thinks it is and That I have no fix other than a rebuild. I'm Not slagging them as I'm no expert! But David seems to knowHis stuff and I'm Getting mixed views? I understand it's hard to examin From a forum post!! But I'd love to know if it's normal or not I doubt it is tbh! Just really hoping there is a easy fix. Il prob give you a call David and chat on the phone.
Cheers

But on another note Looking through all of the information at my disposal I have dug something else up on this matter, I'll pm the op
