Once this starts to happen, the only resolution is to have the gearbox repaired.

Vauxhall Workshop Manuals

This excessive wear affects the gearboxes ability to synchronise the gear speeds prior to full engagement, which in turn stops the smooth meshing of these two parts.

Replacing these worn parts with a new gear will allow for correct gear speed synchronisation and meshing of the synchro ring when selecting this gear. Once the gearbox is removed, it is stripped, cleaned and meticulously inspected for any other issues, before replacing the faulty components with our repair kit.

Once rebuilt the gearbox is refilled with 2. Typically we find that the manufactures do not put enough oil in the gearbox from the factory, so we refill with the correct amount, and it is important to add this to your service schedule and replace the oil annually, refilling with 2.

Although the manufactures quote lbft, we often see standard cars putting out around lbft. The quick spooling twin scroll turbo producing higher than expected torque and long gearing often lead to clutch slip in higher gears.

This is caused by the clutch cover being unable to retain sufficient clamping force between the clutch friction plate and flywheel. Fix We have teamed up with clutch experts Helix Autosport, who have exclusively produced our heavy-duty clutch covers, which resolve any slip issues by increasing the clamping force onto the flywheel.

There are 3 options, first being an uprated Cover and plate to suit the stock dual mass flywheel DMF. For those going even further with power, there is also a sprung uprated organic friction plate available and 6 paddle options which pairs to a solid mass flywheel SMF for the ultimate setup when chasing maximum engine output.

Vauxhall M32 6-speed manual transmission.

Share this:.Background Information Bearing failure on the M32 gearbox is common more so on vehicles which have been tuned, however standard vehicles also suffer. Typically you will notice a whining noise when cruising on the motorway in 6th gear.

The whining will come and go as you press and release the accelerator. The movement is a few cm and very noticeable. Eventually you may start to see movement in 5th and 6th gear as well, if you see this occurring your gear box really is on borrowed time. Vauxhall have used the M32 gearbox across a wide range of cars, the table below gives an indication of where they were used. It should be noted that to combat the failures, the latest M32 gearbox has been modified in an attempt to get greater oil flow around the enlarged 6th gear bearing.

Bearing fatigue and failure is the most common cause of catastrophic failure of the M32 gear box. The most common bearing to fail first is the one which sits above 6th gear. The photos which follow were from my own failed gearbox which show this 6th gear bearing failure. Providing action is taken before any of the bearings entirely fail the gearbox can be repaired by replacing the bearings throughout. This works out much cheaper than replacing the whole unit. It is possible to split the casing and remove the gears without removing the box from the car, saving the amount of work necessary.

The M is a 6-speed manual transmission.

This manual transmission is an all-synchromesh 3-shaft transmission. This 3-shaft transmission has the following advantages:.

In this transmission angular cone bearings are used for all shafts. These bearings require a certain amount of play and pretension. The required amount of bearing play and pretension is achieved at the production stage by using shims under the angular cone bearing in the transmission housing. This diagram shows the location of the gearwheels on the respective shaft. The following exploded diagram shows the location of the components in the M manual transmission. The components of the individual shafts will then be described.

Some Vauxhall Astra J models are fitted with the infamous M32 gearbox. When this bearing starts wearing out, the gearbox becomes noisy when driving in 6th and 5th gear. Follow the link above to learn more about the symptoms of bearing failure, the solution to the problem and how much it costs to fix a dying M32 gearbox. The M32 gearbox is used in the following Vauxhall Astra J models:.

M32 gearbox bearings. As the name implies, it actively changes the damping stiffness of the shock absorbers, depending on the road conditions. Luckily, there are other options. You can have the CDC shock absorbers reconditioned for half the price of a new one.

There are companies that specialize in these kinds of jobs. This can be achieved by using an aftermarket emulator device.

FlexRide shock absorbers. The positive crankcase ventilation system PCV is present in every modern vehicle, and its purpose is to evacuate crankcase gases generated by piston blow-by. These gases are fed back into the engine through the intake manifold, and without the PCV system, the engine crankcase would pressurize.

The PCV system is usually made of pipes, channels and chambers that separate oil from the blow-by gas. The only moving part is the PCV valvewhich is just a one-way valve that controls the amount of gas being fed into the intake tract.

One important thing to know is that in petrol engines, the intake manifold is under vacuum when the engine is idling or under low load.

astra j gearbox

This is because of the throttle plate that restricts the amount of air entering the engine. At low loads, the throttle plate is mostly closed and the engine is trying to pull more air than it is allowed to, which generates a vacuum between the throttle body and the engine itself. This vacuum sucks the crankcase gases through the PCV valve. There is also another air pathway between the engine and the air intake. This one is connected to the intake before the throttle body and its where the blow-by gasses go when the throttle plate is open full throttle and there is very little vacuum generated in the intake manifold.

In a turbocharged engine, the PCV system is more complex because the turbocharger generates boost pressure. Hence, the intake manifold is pressurized when the turbocharger is doing its thing. In these conditions, blow-by gasses are fed into the intake duct before the turbocharger. However, when there is no boost, the system operates exactly the same as in a naturally aspirated engine. I hope I made this reasonably clear.

The car has only just done 30, miles I'm rubbish with car stuff but they have found metal shards in the gearbox and Vauxhall are saying they have no idea how they got there and are hinting at driver error!!! Thanks Shona. Look for some goodwill from vauxhall given the low miles.

Technically out of warranty so they are not obliged to offer anything. However, that price for a new gearbox is just daft.

Look up Gloucester road gearboxes. They are very good and it will be less than a third if the main stealer price quoted. I opened a dispute with Vauxhall today but they have said given the age and the mileage on the car it looks unlikely that they will offer any assistance, I certainly won't be having the work done by them at that stupid price, thanks for you're info Shona.

Most probable is that the seal between engine coolant and gearbox oil has perished in the shared radiator. Allowing engine coolant into the gearbox. HS 1, posts months. Goodwill will generally only be considered for 1st owner vehicles if the vehicle has been serviced within the dealer network and to schedule. If it is then you have a chance especially given the low mileage. If you are willing to contribute then the manufacturer would usually contribute a greater share.

There is a very common problem with the M32 gearbox, the symptoms can vary and some complain of whining but no movement in the gearstick, whilst others complain of movement but no whining!

Generally this is what you should be looking out for:. The gearbox issue which results in all of the above symptoms is a result of the failure of one bearing — specifically the bearing on top of 6th gear. It is also quite common to get a constant whine in all gears from mph onwards, regardless of whether the clutch is engaged or disengaged, which intensifies with speed.

Often misdiagnosed as differential bearings, this is caused by pitted pinion bearings which can be seen on inner and outer races below.

The gearboxes have seen more issues with pitted pinion bearings than earlier versions — this is due to GM changing the bearings to lower quality FAG and NGBC, as opposed to the earlier Timken bearings.

The Cause: Bearing failure can be caused by a combination of things, mainly linked to poor gearbox design. Excessive oil temperatures along with a failure to change the gearbox oil regularly or at all not part of the service schedule.

The cause is typically down to wear and tear, mainly caused with more enthusiastic gear changes. Occasionally these issues can also damage the nylon fork guides, which then also require replacement. Generation 1 — These 2nd generation gearboxes come complete with improved oil galleries and, more importantly larger bearings 55mm vs 62mm OD, as seen below with dramatically increased bearing surface area. The larger bearings help dramatically with the common 6th gear bearing issue — to date we have not seen a bearing issue bar a few light wear marks when inspecting gearboxes in for pinion bearing repairs.
