**Paging DAP** Why would Jason@STaSIS send a gallon of Redline 75W90 GL-5 with my rebuilt tranny?

Update: I missed the "Redline" part in the post. That is definitely corrosive (says so on the bott
le). Definitely ask Stasis about it. Do their rebuilds remove the brass parts? I'd guess not.

We have used it for years............
I know the owner of Redline personally - and they make the finest synthetic oils available. I can gaurantee you that by the time that any noticable corrosion happened to your syncros (if ever) your car would be an antique pile of rusty bolts.
As a side note you could run MT90 also but I have fount that for some reason the 75/90 shifts better in the 01E gearbox.

That doesn't surprise me that it shifts better than MT-90. The FM package in MT-90
is fairly crappy for vw/audi trannys IMO.
As for redline making the "finest synthetic oils available" I'd have to disagree since there are many other synth oils better for the application.
I still think running straight GL-5 is bad for the longevity for the syncros.
GL-5s contain 30-50% more of the corrosive additives than a GL-4 does but a GL-4/5 doesn't.
A GL4/5 also offers the protection of a GL-5. Simply put, its a better designed GL-5 fluid without the high levels of corrosives of a plain GL-5.

Another point.....
Transmissions are usually one of the most neglected items in your car. Think about it - you baby your car, wash it twice a week, change the oil every 2500 miles etc. When is the last time that you changed the trans fluid? It is my belief that you should change the gear oil every 2nd oil change ESPECIALLY if you take your car to the track. Think about it, the gearbox doesnt even have a filter like the engine so frequent fluid changes are even more important.

Probably ok. Amsoil has two 75w90 gear oils that are compatible, one is fairly new
and specific for the yellow metal trannys(link below). I'm running the Severe Gear 75w90 in both the tranny/diff - will likely swap to the "true G4" new Amsoil gear oil vs continuing the G4/G5 Severe Gear now that there is a specific one for us. There are a few other G4 choices in the US as well.
FYI... cold start shifting(or anytime) flow proceedure: Start car with gear in neutral, let clutch out and let it turn the tranny a few seconds before selecting a gear. Easier to select gears with the gears/syncro/tranny wet.<ul><li><a href="http://www.amsoil.com/storefront/mtg.aspx">MTG Amsoil G4 Tranny:</a></li></ul>

Good point, 20k-30k of normal driving will deplete EP/AW and FM additives as well as cause
significant shearing of the oil.
I also believe in doing an early change on a new vehicle to remove any manufacturing contaminants.
10k for track applications seems to be a good recommendation since the operating temperatures will be much higher and the gears placed under more load.
