Gearbox whine in 1st and 2nd

yessiryes

Hi, not sure if anyone can help me, I have a 2009 1.3cdti vaxhaull astra, recently I have noticed that in first and second gear there is a high pitched whine, which dissapears after second gear, the clutch is currently being replaced as it's slipping and I am wondering is this linked to that or is this a whole new problem which is gonna cost me a fortune, i.e a new gearbox? The gear stick is a little jumpy in 5th as I ease on and off the accelerator also,
Thanks in advance

A whine is usually an internal gearbox issue. You might be lucky and it's a clutch issue but I'd doubt it to be honest.
Are they changing the gearbox oil when doing the clutch? That might fix it temporarily.

Jumpy + whiny could be a bearing going - you need to get it looked, if it collapses it can do a lot of damage

Yep will get them to change the oil and see if that helps it, if not I guess I'll be shelling out to get the gearbox fixed, nightmare, this car has my heart broken! I suspected the bearings but was trying to hope and pray. Thanks

Tbh it's an extremely common fault with that engine astra. It will normally need a new gearbox or just a refurb may be a better option. 1st and 2nd is always the gears that go and make the whinning noise on them. It's highly unlikely a gearbox oil change will solve the problem as the damage is done it may slow the problem down a bit.

some of those bearings are available reasonable, get its number when you dismantle box before it gets worse, had kadett years back same problem and got quote from dealership for over £70 at time ,a friend had done his and found that same bearing available for £9 , he was told its same bearing as in a fertilizer spreader,those bearing are made by a number of companies and packaged in dealership brand boxes or in supplier brand boxes for example sparex and you pay extra for dealership packaging eg Opel or whatever. there is difference in bearings such as high speed , heavy duty etc but bearing companies know by number on bearing shell

For sure - occassionally though car manufacturers will get bearings made to their own spec

One Honda gearbox bearing :
- same width, same outer diameter, inner was 1mm bigger compared to a "standard" bearing

- inner bearing race cracked ( that millimetre was missing from it ...... )
- ground down the shaft and used a standard bearing - you need to be careful at this craic though

your'e spot on at that. was the extra size in shaft to give extra strength while retaining existing housing. i would expect opel to be standard , but then in "tiger years" the motto was cheapest contractor got job in most cases and use of standard products suffered big time and now they are trying to repair tarnished images

there were two bearing companies in cork city don't know if they are still in business and staff were brilliant at variants, remember fella with digger quoted over £400 for main rotating shaft bearing and seal , got bearing for around £60 and was sent to Case dealer for seal for hydrashift box in DB 1212 i think, another £40 or so at time.so its worth a shot anyway rather than "bust up"

I'd say it was just their way of making you buy factory parts

It drove on for another 70,000+ miles after that no problem

agreed, but wasn't mileage after repairs a tribute to ability to grind shaft accurately, centering shaft accurately ensured strength, if that was done first day bearing would probably be standard and no revenue for honda from repairs, on the other hand maybe they mightn't even know of variant: rolleyes: who supplies honda with gearbox's. a tv programme a few years ago highlighted designed to fail parts, so design to generate finance from repairs parts could be likely too.

BTW do you remember the days of adding porridge to gear box oil for upping trade in value
