Going to put in GM synchromesh...
 

Before you all poo-poo me for this I'd like to state a few reasons WHY I'm switching.

My 1-2 shift cold is amazingly rough, but once warm its fine
3rd feels a little notchy
Some VW guys run this stuff and sewar by it

Now, what's in my car - Castrol 75w90 - GL5 approved stuff. So I need to get it out of there anyway.

I've read raves on GM Semi-synthetic Synchromesh. The cheaper Pennzoil and QS synchromesh fluids I haven't read as good of things.

So, I need to get the fluid i have in there, out since it's GL5, and I figure I'm going 2 quarts Synchromesh and 1 quart 75w90 GL4.

I'll let everyone know how it goes

let us know how it works out
i just developed a noise in first gear so im going to do a fluid flush and if this works, i'll go with that

Yeah I mean I can't say that as far as longevity goes it will be a true alternative, but even if I can change this stuff every 40k I'm all for it.

good point, audi says their fluid never has to be changed

RE: Going to put in GM synchromesh...
 

Yeah, the fluid doesn't need to be changed, just the transmission... :D

Audi... So blissfull in their ignorance. The only company that claims to have magical "lifetime" fluids. Turd sandwiches...

Must be using synlube

Update: I was reading on the vortex that Synchromesh is nearly an 80w, which means it's pretty close to GL4 spec. I don't think I'm going to put in any 75w90 after reading that and I'll just go with the 3 quarts of synchromesh.

BTW: I might not be able to get this done this weekend as the weather may be turning on me... [:@]

That is how they can keep down calculated maintenance costs. If there is no scheduled maintenance or need to change it, they can advertise how inexpensive upkeep is.

Probably devised by the same guy in marketing who said you can go 105K miles before changing the timing belt.

LOL... the point is, after the warranty I doubt Audi gives a rip...
