Whining Noise in Reverse Gear - DA9?

Hey guys, im lookin at buying a 1990 DA9 integra, i have driven it it is seriously immaculate and only 120,000kms on the clock, drives beautifully in all other gears, does not crunch in any gear etc. although in reverse it makes an odd whining noise, i had a read up of a thread about it on the EM1 civic's and there were a few people with similar noises, and some think that they have a straight cut reverse gear - hence the whine. Any help and/or info would be muchly appreciated.

Cheers, Reece :thumbsup:

ive heard of some ppl having the whining reverse noise when the car is under load (e.g reversing up a slight slope) and then it kinda smells that something is burnt. What could it be?

The only other sorta things i read it may be is the gear linkages are a little out ot whack or the clutch does not engage properly in reverse gear.

definitely no burning smell, was reversed down a driveway though.. therefore no load.

they r two different whinning noise when in reverse.

1, is the normal constant whine and would increase in pitch depending on how fast your car is moving. - this is normal

2, this noise is more hi pitched and would increase in noise depending on your rev level - this is when your clutch isnt engaged properly and your burning ur clutch. afterwards your get a bad cooked smell...

both sound like remove cars.

i have always thought it was just the straight cut gears, because that is exactly the sound that straight cut gears make, it happen on my car and a few other cars i have driven also.

Do you want the whole gearbox with straight cut gears? It's quite expensive, I think there's a place called Pfitzner Performance Gearbox in SA who do dog boxes as well as standard synchromesh gearboxes. They do EG, EK and DC2 with a FD of 5.545 for $9350. Have a look at their website if you wanna know more about it.

it is because reverse is a straight cut gear.
According to the pros -

Quote:

A. More directional application of force allowing for less power loss. and B. Higher acceptable loads until failure.

Basically making the transmission stronger and more efficient , but with the only offset being the loud WHINE.
All forward gears are helical geared giving lower noise.

Yeah, the reverse gear is straight cut, hence the whine. It can be straight cut coz its the only gear goin backwards and doesnt need synchromesh for a smooth transition to the next gear.

Most if not all manual trans cars have straight cut reverse gear, hence the whining.

most cars make a whinning noise in reverse... also u will notice alot of race cars do it in forward gears 2..

it is called straight cut gears... which makes them stronger... it is a common mod for wrx's as the have weak gearboxes that cant hold the power of modded ones :)

hehe, ad pq point :P :P

Hey, i got the car, pretty sure it's something else other than the straight cut gears, it sounds like the clutch is badly slipping or something, not really sure to be honest but it is actually more of a loud clicking kind of noise, but it's weird because as i mentioned in any forward gears the clutch is perfect no slipping, crunching etc. and smooth. i'm going to get it checked out soon

My EF9 kind of makes a whine, not super loud, probably 30% of reverse sound dB in foward gears. It is proportional to the cars speed not RPM. Kind of like this.

RPM: 1st brrrmm, 2nd brrrrrrrrrrmmmmm, 3rd br brrrrrrrrrrrrrrrrmmmmmmmm
SPEED: wwwhhheeeeeeeeeeerrrrrrrrreeeerrrriiirrrrrrrreeeee riiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

LOL >.<'

Can LSD's make a whine too?
