Changing oil on manual gearboxes
Hi
Is it necesary to change the oil in those trans.? I think yes it is, because nothing lasts forever.
But the change intervals? 50.000km????100.000km???? more than that???
Thanks

Yes you need to change your tranny fluid/oil and most recommend 50,000 but it could be less if you drive hard and the manufacturer may have different specs.
ALSO: don't forget differential fluid if it's RWD or AWD.

I don't think that the differential is in the gearbox on the fwd cars.
i think that they are separeted things... or not? O.o?

Thanks
I think they are on the same box and they use the same oil (on FWD cars). I saw once the trans. of an Impreza WRX and the front differential was on the same transmission.

The diff was part of teh box, in the clio v6 i saw bing stripped. and thats practically a laguna engine and box turned round and put in the boot!!!
Theres no separate casing in on my car. and the drive shafts exit from either side. So its definately in there. Actually thinking about it, it definately is a part of the grearbox in teh FWD car.

A FWD car doesn't have a separate differential in the classic sense of the word, like a RWD car. The differential in RWD (and the REAR diff on an AWD car) changes the direction of the drive. In a RWD car, it changes the direction of the power from the driveshaft (which is north/south facing in the car) to the axles (facing east/west). But a FWD car does have a differential, inside the transmission case. I haven't worked on FWD cars enough to elaborate anymore, but I know that a very worthwhile upgrade on FWD cars is to do an LSD (Quaife is very popular for Honda Civics and the Ford Focus'). I believe that changing the transmission fluid in a FWD car includes the "differential".
In response to the original question, yes, you do want to change the transmission fluid, even when they tell you it's a "lifetime" fluid. That's all BS. While the fluid might resist breakdown better than old style lubricants, there is still the fact that there will be the development of debris in the fluid just from wear and tear on the gears. So, you want to change the fluid and the transmission filter.
50,000 miles is a good number, but like stated above, the harder you drive, the more frequent you should upkeep the fluid.
Good luck.

it is advisable to do, be also sure to clean the breathers if any and don't skimp and use a good oil, synthetic if the car is rather new...it's amazing how much crap you can get out of the tranny when you flush it.... :x

It's actually better to try and stick to the manufacturer's recommended "gear oil" as we call it here...if this is not available..stick to the popular brands. The type of oil you will use will also vary depending on the type of diff you use...whether open diff or lsd.. 8)

I heard that the new blends of synthetic oils don't affect the rubber seals anymore and that you can go back to dino-oil if you want...I don't know for sure, since I've never gone back...
