Oh fun fun. Gearbox has the death whine in 5th and 6th so it's going in for a rebuild next week.

It was the M32 gearbox that ultimately put me off getting a Bravo (I wanted a T-Jet) as our family car.. I bought a Ford Focus instead :shock:

At least it's not FIAT fault. The blame lies squarely with GM.
Speaking to the transmissions guy who is doing the repair and rebuild on mine he thinks that the issue is not a fault with the bearings not being up to spec. It's more that when the boxes are built that they pre-load the 3rd shaft too much, applying too much force on the bearing along the shaft. This ultimately causes them to fail. His solution to reduce this pre-loading slightly by using slightly thinner shims when re-building it.
I know some people have no issues whatsoever, Rob for example and you know that his Brava's have been driven with more gusto than mine has likely been in the past. I doubt if mine had ever seen 5th gear until I owned it. Its only averaged 3000miles a year so far.
Hopefully this will be the only time that I'll have to repair this fault, we shall have to wait and see.

Hopefully it does sort the issue out for you, interesting to hear that your transmissions guy believes it's related to the preload and not under specced bearings (which seems to be what a lot of the Vauxhall owners believe the issue is) . As you said some people have no problems with the gearboxes at all, unfortunately I wasn't prepared to risk it this time around. Never say never and all that :D

It is a fault with the gm chocolate boxes as I call them as we are constantly sending them off at work to be rebuilt! Utter rubbish quality!
