Is my gearbox on the way out?
I think I know the answer, but anyway... Got a hawkeye wrx on the standard 5 speed, but running 340bhp, 350 ftlbs. I know the (original) clutch needs changing, at the last map it was slipping quite badly. Plenty of meat on it, but can't handle the torque. At a service last year I was told the gearbox was getting a bit noisy, then today I noticed a new noise. Putting my foot down in 5th between 3000-4000 rpm got a loud rattle coming from the mid-front of the car. Didn't happen with light throttle, at other parts of the rev range, or in other gears. I'm guessing fifth is getting ready to give up on me, and the torque surge with an open throttle between 3-4k is straining it But, before springing for some major work I thought I'd see if anyone had any other (cheaper!) ideas as to what it might be

when clutches start to wear its important that you get the clutch changed ASAP or the knock on affect is to start chewing up gears because of the increased torque that is not being held by the worn clutch and putting the strain on the box my first port of call would be to get a uprated clutch.can you still engage all the gears? Maybe check the gearbox oil for level and quality and change for a better quality oil while changing the clutch.my wife has blown a couple of gearboxes up and usually they start with the whining noises then hard to engage gears then gear completely gone.all the best with your investigations.

Cheers mate, that sounds about right. It has been getting harder to change gears, what was a very rare crunch when changing is now up to occasional, still a bit of life yet I think but I've decided to bite the bullet and have ordered a six speed conversion with appropriate clutch & flywheel from API. Looking forward to the extra gear, not so much to the credit card bill!

We should have that for you later next week Dai, we are just going through the box now before re-assembling it ready to fit.
Good Choice!
And thanks for your custom. David APi
