General M32 Gearbox in t-jet 150

I'll give it a go - cheers. Should the gearbox oil get low over 43000 miles? Does that indicated a problem in itself?
 
Just spent £2200 getting my noisy gearbox and clutch sorted on my Mjet sport with 28000miles on the clock. When the gearbox was stripped parts of some teeth found to be missing and the dual mass flywheel was also about ready to fail. This is not the M32 gearbox, so you pay your money and take a chance with any box.



I bought a 2008 mjet 150 sport which had 22000 miles on the clock when i got it and i did not notice any problems at the time, i am a fitter by trade so i know alittle bit about these things. 6 months later it got very noisy and i got the box stripped and thats when they found the gearbox and clutch problems. I think the box is a C530 6 speed. I am in my sixtys and do'not thrash the car

It shouldn't drop in level at all to e honest, will either be a leak (potentially CV boot) or never correctly filled in the first place. If it's the latter I fear it may have caused slightly more long term damage.

Worth checking the oil first though.
 
my old stilo 1.2 ate three six speed boxes, the first box had a problem with third and fourth so under warranty it was repaired, only for the gearbox to then start making the worst noise ever, fiat uk refused to pay out until it exploded on me, then the next box didn't last 5 minutes, then the final box was fine for a lot of miles until one day I had a wheel bearing sound, but only once the car had warmed up. I jacked the stilo up and then ran it in drive in the air and the noise, like a helicopter, was coming from the gear box. so I got shut of the stilo.
 
My M32 is in Fiat garage.


They are going to change 6 bearings (ex. diff). The bearings of 5th and 6th gear were the problem. But they will change all 6 gearbox bearings for 3 years warranty.


As I know, the biggest problem is SNR bearing 55574107 (old number: 55188083) not TIMKEN.


Total bill should be 550€ (445£).


Clutch is OK.


When I get the car I could write more.

This is all pretty worrying to hear to be honest!
I have a 2008 Mjet 150 Sport that has 59K on it which we've had for 2 years and no gearbox / clutch issues so far. My wife drives it normally on short journeys and I drive it occasionally and show it very little mercy but I'm not hard on cars because I know I'm the one who will have to fix them if I break it.. Point is I'm looking at 150 tjets as that was what I wanted when we got the mjet because of the short journeys and quicker warming up etc. Also not hauling 100kgs extra around has got to help.
I'll keep an ear out for gearbox whines on any test drives then..(y)
I have a friendly bloke locally who does gearbox rebuilds for £150 if it all goes tango uniform in any case. ;)
 
Driving style has nothing to do with this problem.


I'm first owner and I drive very gentle.


The problem is poor quality of SNR bearing and that's it.


I drive mainly in city and this could be reason why I have this problem so early. Cars produced after 2006 have this problem more often than cars before 2007 and after 2009.


This is my opinion.
 
It would appear that I'm another M32 gearbox victim. I've got a 57 plate Bravo 150 sport with 67,000 on the clock that has developed a severe shaking. It feels a bit like the wheels are out of balance, but I've just had new tyres so I know that's not it.

It eases when I press the clutch or go into neutral. I'd noticed a whirring a few weeks back, but didn't think much of it. I've just had a weekend with a couple of long journeys, and when I got home last night it had got pretty bad.

It's going into the garage tomorrow to be looked at. The mechanic thinks its a driveshaft problem, but having read through this thread I now think it's more severe than that. I'm assuming that it's the gearbox bearings issue that others have mentioned.

Does this fit in with those that have had this problem? Also, how much am I looking at? I'm absolutely skint right now, but giving serious consideration to getting another car.

Get the wheels rebalanced. Sounds like they haven't been done properly tbh, and is the most likely IMO.

Thanks for your reply. The problem was starting before the new tyres were fitted, but has got steadily worse. It also gets worse the longer I'm driving. I had to do a 240 mile round trip yesterday & by the time I was home I couldn't wait to get out of the car. I just went for a spin this evening so I could listen out for any signs, the 1st 10 miles hardly anything, after that it starts to show. After about 20 or so miles it's terrible.

As I turn into my driveway there's a bit of a bump & the wheels are turned tight right. As I come in there's is quite an audible clunking that comes from the drivers side front wheel. I had it looked at a month or so back & was told it was a ball joint, but when it went for its MOT it sailed through. I'm starting to think that it's all connected & that it is the driveshaft making the noise and the vibration. Hopefully find out tomorrow, though I don't want to shell out hard earned cash if it turns out to be something else.

Now you've told us more it sounds like its possibly a failing CV joint. If it is then get it done ASAP as the car will be unsafe and will either leave you stranded or seize and potentially do your drive shaft or gearbox in.
 
Hi

My gears are starting to get stiffer between changes. Its normally engaging first and then between first and second that's stiff. Other gears seem fine and when warmed up first and second feel okay.

I've also noticed that the gear leaver moves when in first gear and lifting up the clutch (getting the biting point). It jumps back quite a lot.

The car has only done 30k miles.

Are these symptoms of the gear box failing?

Thanks

Dont think so. It could be lower engine/gearbox mount, gear selector cables etc.

Also sounds that came from gearbox area while driving could be from dualmass flywheel-it is a big heavy few-thousand rpm rotating mass with few moving parts inside it.

I remembered Punto mk1 GT from almost 20 years ago-his 136HP and shot (not linear as t-jet) of 200Nm at 3000 rpm transfered via small 180mm clutch plate an one mass flywheel to that small 5 speed gearbox.

I know few guys with those cars and 150 000km+ on the clock, but no one NEVER had gearbox failure.

So after 20 years M32, a German technology gearbox is 40 years behind with its low chinese quality build.
 
Job is done.


for 457£ (563€).


I gave you wrong info about bearings. Mine had all six TIMKEN (not SNR)


In attachment you could see bearings.


TIMKEN to Fiat Part#
NP854792 --> 55574107 x2 (problematic bearing)
NP238750 --> 55181940 x2
NP797735 --> 55574104
NP030522 --> 55574101

They had to cut bearing to remove them. Because NP238750 looks like as destroyed.

This thread really got me worried. I have a knotchy feeling when shifting up to 3rd gear.
So i will be replacing the right CV gearbox seal, and at the same time replace the oil. which oil should i get?
 
Yes, that's good point to replace oil.


They put Tutela Matryx, but I'm going to change gearbox oil after 2 years.


I have considered Castrol Syntrans Transaxle, not Multivehicle as you could find here on web. Because, only Castrol GB recommends Multivehicle, but other Castrol sites advice Syntrans Transaxle.


So, I was confused, and I sent an e-mail to castrol, and I get following response

thank you for your e-mail.

We are sorry, but as German Castrol we only supply the german market and therefor we can give you only informations about our products supplied in Germany. Please note that our products and their specifications can differ from country to country.

If you are a customer localized in Germany we can give you the following advice. The indexing gear box of your Fiat Bravo 1.4 16V T-jet (110 kW) built in 2008 needs an oil with the Fiat specification Fiat 9.55550-MZ1, as you already remarked. This is a specification, which demands an oil according to API 4+ with the recommended viscosity of SAE 75W-85. Fiat advises Tutela Car Matryx 75W-85 by name. Our oil Syntrans Transaxle 75W-90 matches with the requirements of Fiat and can be used excellently. It is a fully synthetic, heavy duty transaxle gear oil with high thermic stability and fits the mentioned requirements very well. If you are not a customer of the german market please directly contact our colleagues in your country under http://www.castrol.com for your request.

Ok, that is more likely.
So while they were in gearbox, those bearings were complete, no damages like those in pictures?

But originally they were Timken, so best quality that you can buy for gearbox, and they still are no good.
And replacing them with the same quality :confused:
