I changed the transmission oil on an Astra H (2007) with the M32 after around 110,000 km. Open the inlet screw (10 mm hexagon socket, new screw with magnet, old one without), level the car and then open the drain screw on the driver's side (12 mm hexagon socket) and let everything drain for a longer time. For new oil I used the Castrol GL4 TRANSMAX Manual Multivehicle 75W-90 oil (use GL4 only!). 2.4 liters come in, up to the control screw it would be 2.2 L, but don't open it! Or if you really want to open it, put the 2.2 liters in until it drips out, screw it shut and put another 200 ml in. Never had any problems!
Came on this site after finding bad oil leak from gear box on my meriva b, where the f is top up plug,came on this site and you found it for me thank you very much. From frustrated gear oil top up plug seeker:)
Exactly what I needed on my Astra 2.2 Direct, as it's got 150,000km on the clock, and I don't think the gear oil has ever been changed. I've only owned it for 2 years, and it's been great, but I noticed a whirring noise in 6th gear, and it was getting difficult to shift smoothly. I've overfilled it with 75w-90 GL5 and it seems happy now. Thanks for such a great video.
@@missionfitnessarmyfit1466 Not to overflowing. Drained as much as possible (tilted the car to the left, to get every possible drop out), then put in somewhere between 3.2 and 3.5 litres. Can't remember the exact amount.
Done that last night. Straightforward thanks to your video . Surprised that I only drained 1.3 litres of old oil 😬 and it has been changed 4 yrs ago by the previous owner.
I had the same with my astra vxr. I put 2.9l of fuchs sinto fluid 75 80 in 3 years ago and its been silky smooth untill the last few weeks it doesn't go into 2nd that easy when the outside temp is below 0. Gonna do another change next month so will be interesting to see how much oil drains out this time
I have this transmission in my 2014 Chevy Cruze. I learned very early on of the importance of having both the right type of oil and the right amount. I use amzoil synchromesh and put in 2.4 quarts.
I run moly-slip G in my box it looks after the bearing a bit longer also racing oil, it can stand the heat better, it's a bit more expensive but worth it.
I am with 1.4T B14NEJ and assume the M32 gearbox. Now after 9 years and 80,000km. I notice a whine at 6th gear and a rough change when the engine is under load. I think I will change the gear fluid soon, but at my specs said GL4 and 75W specs. Why u guys in the commends are useing GL5? Thay fluid *GL5 is for hypoid differentials. It can do dmg to the metals in the manual transmission.
9:31 please don't show bad habits of removing bolts with a torque wrench. That's a terrible use of a wrong tool for that job. Good video apart from that.

might of only had 1.7 as you had car jacked up on one corner only not both sides but doesn't matter because you now have nice full gearbox of oil so very nice for bearings. LIKED
They changed the oil level in the m20 m32 gearbox due to it not been the right amount. The 5 or 6th gear depends on model was missing or didn't factor in an proper oil fed to that bearing and they wore out.

Hello just I bay the vauxall combo 2007 when the car is cold make the gerbox strong and noisy when u try to change the gears , after 10 min u can drive fine , can same bady tell me need to change the gerbox oil ?? Thank u
Hi, if it's the 1st generation of the m32 gearbox then you should add half a litre extra, if it's the 2nd then you can put only 2 litres but it's better to have about 2.2 litres.
Hello my friend. I have this gearbox to my opel insignia grand sport 1.5. It makes a noise at neutral that it stops when i press the clutch. What do you think about that? Thank you
HI, I know that we have to overfill the gearbox slightly and that the oil level plug remains untouched we should use around 2,9 ltr but if I want to top up without removing the oil level plug how do I know how much oil to fill?
Hi, if you just want to top up without removing the level plug then you cannot know the quantity inside, the best thing is to drain the oil and then refill it.
The second improved end case has oil galleries added to help the bearings get oil circulated better. You can see the galleries from looking at the casing. Have a look at a revised m32 end case upgrade and you will see the difference
The only way is with sum strength using a bar attached to wrench or solid long 10mm allen key, hold it in place and pull with all your energy. It will break loose but always realese the fill plug before draining the old oil just incase it don't come loose and your left with a empty box
Great video! What is the point of the 'level' hole? Would you fill until the oil exits this hole? Or is it easier to just drain and add 2.7L as you have shown. And is it necessary to jack up both front wheels?
First drive the car for 20 minutes then jack both sides up and drain the oil, add 2.7 litres of new oil, then drive the car and at the end you can remove the level plug and some oil should come out from the hole. But in this gearbox is better to have more oil than less oil. (I didn't record it but I jacked up the other side and lowered this side just to be sure to drain all the oil).
My gearbox is a m32 in a grande punto , i notice that when put the 2nd gear more directly it grinds some times not always and if i shift slower apears to be good , any tips?

@@CLIFTYPOPS yes, you need to hold the switch for 3 seconds when the windows are fully up then lower the windows and hold it again. You may have to repeat more times.
No need to go through the trouble of removing the battery. The oil can be pumped in in a reverse order to draining. Like it is done with 722.9 transmission oil change.
@@Wisuy "for gearboxes" dude, seriously? A tractor or semi-truck also have gearbox but its way different than a smart car gearbox :D And by the way, my Opel astra J requires 70w gearbox oil which is really hard to find so I put in 75w instead (its thinner than 75w80 so more close to 70w)
So I unscrew the level check bolt and added 1.7L oil, plug my finger in the level check hole, no oil. I fill it up with another 0.5L, now the oil started to drain at the level check hole. So I put back the level check bolt and added another 0.4L oil. Now it shoul be 2.8-2,9L oil inside. It came from the factory with only 1.9L. oil!!!! (I read that 0.2L oil will left inside when draining)
The manual of my 159 states it holds 2L of oil. Most gearbox experts say pour in 2.5L to prolong the life of the bearings on the secondary output shaft.
