Gearbox Issues :(

[tommyboy1289]

Right I'll try to describe as best as I can. 

Got an astra 1.6 petrol (5 speed box). Hate the car but hey ho.

Noticed a noise a week or so ago, it almost sounds like it's whistling slightly as I was going up through the revs, mainly around 2/3k.

But tonight I've noticed something else, when I'm going slowly through traffic it sounds like somethings grating, as I move faster the grating gets faster, but when I drop the clutch it stops and starts again when clutch is lifted.

Sounds like it's coming from passenger side of the car.

Anybody like to hazard a guess as to what it might be? And what it's gonna cost to put right, hoping it aint a new gearbox job :(

If your car is now out of warranty? I'd take it to an indy gearbox specialist.
The 5 speed box is generally more reliable than the 6 speed m32. Although I did have an Astra H that had a slight whine in 5th at around 55-60. I then part ex'd it for a J with a m32, then my troubles begun lol.
It may also be a clutch issue. I don't think your has a dmf to worry about (bonus), being the 1.6vvt engine.

Yeah out of warranty

Now diagnosed.....there's a bearing gone in the gearbox and a problem with the output shaft, luckily a newish friend is a gearbox guy so he's replacing the bearing and machining the shaft, also the concentric slave cylinder is buggered so having a new clutch kit fitted which is sensible to be fair as it's all out anyways. Also needs a new clutch pipe?

Anyways all repairs and parts it's gonna set me back £630 so not as bad as it could of been.
