T5 Oil Change

[roysum]

I have a small leak somewhere on my T5 gearbox, it is only small.

Q1....Would the viscosity of say 75w-90 be thicker than the ATF in there at the moment ?

Q2....How would I drain the present fluid ?

Q3....Where's the top up, do I do this from under the car or via the cockpit ?

Looking fwd to your knowledge, ta Roy

Can't help with the first one, but to drain is easy, there is a drain point on the gearbox, and the fill point is on the side of the box, accessible from under the car.
It doesn't take much fluid either IIRC

Thanks

From memory it is 2.5 litres to fill from empty.
There has been some recent chat about alternatives to ATF, conclusion I drew was stick to ATF..

Stick to ATF or you could be looking at more than a leak. Think of oil leaks as automatic chassis protection!

Ok thanks chaps. Definately a discussion point, lots of opinion that ATF isn't as good !

Any T5 experts out there ?

Hi Roy, It was me that said about putting synthetic atf in gearboxs as an alternative, you definatly don't want to put 75w-90 in there as it is to thick and will make the gearbox very stiff and possible damage it. The synthectic alternative is no different to changing you engine oil to synthetic (theoretically better) and it does make gear shifts a lot lighter only problem being I've always fancied synthetic oils find leaks quicker so in your case I would of thought your best way would be to keep topping it up with ordinary ATF, and until you see a few drips under the car when you park up you will probably be o.k. You fill it up via the level plug on the side of the gearbox and you will need a swezey bottle with a tube on the end to get it in.

Dexron 3 here no complaints(cos i buy in bulk),please bear in mind ATF is similar to a 30weight oil SO NO THICK STUFF and bear in mind the job that ATF as to deal with in an auto trans so a manual box is a walk in the park for ATF oil,i use to build Honda auto transmissions so believe me when i say its severe.

That's convinced me then......stick to it, top it up occasionally and cure the leak in the winter when I do the chassis.

Thanks again everyone !!
