Ahh I see, I bought a getrag bearing rebuild kit to try rebuild it as I assumed its the bearings, but the guy is saying I need a new gearbox as it has to be something with the cones :/ (whatever those are in a gearbox) but as I said, it still runs very very smooth... including reverse gear.
The cones are for the synchronizers and provide smooth friction surfaces for easy engagement of the shifting mechanism/synchronizers. I find the explanation strange since you indicate you have no problems shifting. I would have expected it would be difficult to get into gear.
Do you have any noise sitting at idle in neutral? Any noise that changes with clutch pedal engagement?
Is the noise only when the car is in motion and in gear?
Did you check for transmission oil leakage? Low trans oil levels will also result in a grinding-like noise when driving.
The noise is only when the car is in motion and in gear. Gears go in and out inc. reverse, very smoothly. Sometimes its a tad 'hard' when going through the slot but very smooth. No crunches when selecting gears.
From your description it sounds like the input shaft bearing or low transmission oil level. Regarding the bearing, unfortunately the only way you're going to get a definitive answer is to pull the trans.
The good news is you'll eventually resolve your problem. The bad news is that on the Mini, the gearbox is a bugger to get to.
So MINI is still stuck on the jack cause my gearbox is stuck there in the UK cause of the snow and I'm very frustrsted. To top that, my car is on a jack taking half my mechanics garage and they are frustrated with me.
Why MINI parts are so hard to source here in Malta... Grrrrr
I only love british cars but need a reliable one. I love my MINI so will try stick to it, thinking of getting a classic mini and restore it, if this one ever needs to find a new home.
Though, to find someone that takes care of it, as much as I do.. it's one tricky sale.
EDIT: @The Nun.... I bloody hope not haha or a friggin yaris... No no... There is no soul and passion in those cars. I bought a MINI because it's a reliable car (most of the time), its fun and nimble on the road and friggin' great handling, especially on a tiny island like this.
Sad to comment about it's clutch and gearbox issues... that are known flaws and BMW never took care of them and their power steering.
