Hi there,

Just wondering, but does anyone elses manual gearbox whine like a supercharger under hard acceleration or is mine on the way out? i was hoping it was a trait to the car or something, but that is probably wishful thinking...my car is an early BA '94...with high milage and has made the noise since ive had it. Any info appreciated e.g what could be causing it!

Cheers-->Mitch.

it's the twin cam system most probably, mine does it under full throttle. starts at about 4k rpm, all the way round the rest of the rev range. sounds lush at about 6/7k rpm!

mine's a 1.8 by the way...

Ah yes...sorry, i also have a 1.8, thanks for the quick reply, glad to hear it may be a normal (and spunky ) sound.

--->Mitch

it sounds great doesn't it! i was happy when i found out it made that noise! i wonder if you can hear it as the car passes by....

The exhaust on my Lantis had a small hole just astern of the cat when I got it. When accelerating through the lower half of the rev range it sounded just like gearbox whine. A quick weld cured it.

Even with high mileage, you shouldn't get gearbox whine like that. If it's not the exhaust or just the natural sound of the engine you're hearing it's more likely worn driveshaft splines (which are straight cut ). The forward gears in the gearbag are helically cut to reduce noise (sacrificing power!). Reverse is usually effected through a straight cut idler which gives that characteristic reversing sound.

I think every1 is forgeting that this whine could be also be the gearbox is low in oil
Id be getting your g/b oil level checked asap dude,when i had an ouput driveshaft seal let go on me i lost most of my oil and it started whining

A driveshaft spline doesn't sound promising...nor low oil. I had the big 200k service done about 8months ago incl gearbox oil change, maybe they buggered something up then...but ive been driving a while like it this without side effects...yet. Will get checked, thanks guys.

(by the way, on my bill from that service it had castol dextron [u]AUTO[/u] oil listed...can they use this? an error on the bill?...or something else..... )

Some people do recommend using ATF in your manual box, although it may just be an error on the bill. Some cars even used engine oil in the gearbox. Engine oil, gear oil and ATF aren't really that different in principle. You could always go back to the garage that did the service and query it. Drop your whining noise into the conversation and see what they say.

being curious, i investigated the whine i was getting. accelerating through 2nd from say 20-70mph, the whine starts at about 45mph, and stays until you change, and it increases in volume the more revs the engine is doing. people have been saying that the gearbox might be the culprit, so the final test was rev the car at a standstill, and the whine was the same. my logic says that the engine must make that noise naturally...

With the car at standstill, did you have the clutch down or was it in Neutral?

Mark

tried both, sounded the same....

I doubt it's the gearbox then

Mark

thought so, was happy to find that! does anyone else get the same whine?

in that case then it could be a whining belt, thats not uncommon, if i accelerate hard in 1st in my MX it whines but dont in other gears, strange,

on the other hand it could be a charateristic of the cars, My brothers and my girlfriends F's both have a slight whine.

I think the "whine" is the exhaust....Mine does the same...She starts to purrrr at higher revs just as you described :P

I fitted an new exhaust tip on my 1.5 (the old one fell off!) and from then on it would whine at 3,500rpm, freaked me out to start with until I realised what it was.
