tranny oil

HI there, just fitting my new decoupler (from Florian) before heading into the bush for a week. I need to replace the tranny oil after fitting and wondered whether the oil available at Super Cheap Autos is ok and also how much I would need to buy for the refill (for replacing the nosecone). Super Cheap have Castrol Syntrax Transaxle & Manual Transmission Fluid - 75W-90 at 28.95 per litre. Or there is Nulon Smooth Shift Gear Oil - 75W-90. THe alternative is genuine vw oil that I should be able to get from Rex Gorell VW in Geelong.
Many thanks folks

Nick
Nick,
Rudi, syncro drivetrain guru from Bribie Island uses Castrol Syntrax Transaxle & Manual Transmission Fluid - 75W-90 in both the transaxle and front diff. Its a GL5 fully synthetic. Several others including myself have the same fluid in both. Anyone wanted to quibble about the need for using GL4, take it up with Rudi. Good luck.
Cheers.

That sure is backwards from the conventional wisdom here..
which has  'always been'
GL-4 for transmissions with synchronizers,
and GL-5 for differentials.

more like it ..
don't use GL-5 in transmissions,
but yes in normal differentials. ( like not limited slip type )

You are 100% correct Scott
yeah, I see the poster corrected himself right away.
 I shoulda read more of the thread before posting.
 
And I gather there is a trans guy there who says GL-5 in transmissions.

.......and the poster should be more careful...

HI, I've got myself a bit confused now as to which oil I should use. It seems the majority say GL4? Do Super Cheap sell the right stuff, and when fitting the new decoupler nosecone, is that part of the transmission, or the differential? DOes anyone just reuse what is drained out? Many thanks.

Read your owner's manual.

the decoupler is part of the transmission, nothing to do with the front differential.
So GL-4 gear oil would go back in the trans after installing a decoupler ..assuming it's the kind that goes on the nose of the trans.
 
Putting the old gear oil back in, unless it's fairly fresh is not a good idea.
Check for metal particles on your magnetic drain plug ..
there's almost always a good bit of metal there...
and that's from wear in the trans.
 
Syncro Vans are pretty rough on their transmissions just in normal operation.
in other words...
you can hardly have too high a quality gear oil in it, or too fresh gear oil.
They need all the help they can get.
So 'normally' ...
as I said, unless you know it's pretty fresh stuff..
the old is not put back in ..
or perhaps to run it a couple of weeks until you put in a whole new batch of gear oil anyway.
 
to help avoid confusion..
where there are synchronizers...use GL-4 as in the trans ......, and there's a differential and ring & pinion in the trans of course..
but the need for GL-4 for the synchronizers determines the gear oil in the trans, and the transmission's R & P is happy enough.
 
the front differential , not having any simonizes, gets GL-5.

In terms of brands available at super cheap, you could use castrol vmx 80. This is a mineral oil and gl4. If you want to get fancy and stay gl4 you could by Syntrans (note not syntrax). This is synthetic but I don't think super cheap stock this. Please do drain the transmission and refill with freash fluid. Greg E

HI, I've got myself a bit confused now as to which oil I should use. It seems the majority say GL4? Do Super Cheap sell the right stuff, and when fitting the new decoupler nosecone, is that part of the transmission, or the differential? DOes anyone just reuse what is drained out? Many thanks.

Nick,
Rudi, syncro drivetrain guru from Bribie Island uses Castrol Syntrax Transaxle & Manual Transmission Fluid - 75W-90 in both the transaxle and front diff. Its a GL5 fully synthetic. Several others including myself have the same fluid in both. Anyone wanted to quibble about the need for using GL4, take it up with Rudi. Good luck.
Cheers.
Ken

HI there, just fitting my new decoupler (from Florian) before heading into the bush for a week. I need to replace the tranny oil after fitting and wondered whether the oil available at Super Cheap Autos is ok and also how much I would need to buy for the refill (for replacing the nosecone). Super Cheap have Castrol Syntrax Transaxle & Manual Transmission Fluid - 75W-90 at 28.95 per litre. Or there is Nulon Smooth Shift Gear Oil - 75W-90. THe alternative is genuine vw oil that I should be able to get from Rex Gorell VW in Geelong.
Many thanks folks

Nick

There's more to oil than just GL-4/ GL-5.
Syntrans 75W 85 is GL-4 but not recommended for hypoid differentials.  It is recommended for transaxles but many modern front wheel drive transaxles do not have hypoid differentials.
VW engineers to my knowledge are not testing new oil products in their old gearboxes.
The main concern for GL-5 in gearboxes is the higher concentration of additives and their eroding effect on yellow metal particularly at high temperatures.
Syntrax 75W 90 however, is specifically recommended for use in manual transxles with superior syncroniser performance.
Ron has measured gear oil temp in a VW race transaxle and found it to run 30 degrees cooler with syntrax than the previous oil he was using.
Syntrax 75W 90 is an EP ie. extreme pressure rated lubricant.  This provides protection for the crown wheel and pinion, a highly stressed component in our gearboxes.
 
So as I see it, Syntrax provides exceptional protection at the risk of yellow metal erosion but this may not be a concern at all in this product.
 
This is just my opinion based on the information I have come across this far.
