Post by: mk1vdub on November 21, 2004, 09:16:28 am: I was recommended redline MTL oil, which is great, its even helped with the dreaded 'second gear crunch' syndrome.

Post by: RAMMSTEIN on November 21, 2004, 09:40:35 am: I use Redline MTL in my Passat TDI's tranny.

Gained anywhere from 3% to 5% increase in fuel economy with it (70W80 vs 75W90). :twisted:

Post by: TDIMeister on November 21, 2004, 05:14:01 pm: I've been using Redline MTL since 100k km (now 269k) and I love it! I had the same experience, too, regarding the second-gear grind. In cold climates, no question MTL is the favourite of many.

Post by: srivett on November 21, 2004, 05:35:54 pm: The only "decent" GL4 I could find was Canadian Tire SemiSynthetic 75w90. I went everywhere and all the synthetic oil I saw was GL5.

EDIT: -35C and this stuff felt really thick. At first I thought it was my linkage but the thickness went away while driving so I don't think so anymore. I've never run the stock oil at this temp but I imagine the semi-synthetic isn't a whole lot better because it felt really gooey when swinging the shifter around in a circle.

Post by: Rat407 on November 22, 2004, 04:11:23 am: I installed AMSOIL's 80w-90 GL4 rated oil and it has made shifting way better.
Synthetic gear oil in general will help especially in the cold. If you stick with the reputable brands, Mobil 1, Redline (a favorite of many on here) AMSOIL and Royal Purple to name the most popular.

GL4 and GL5 are differences in the additives in the oil. Many will tell you not to use GL5 if you have an older transmission due to the additive in it will attack certain metals inside the tranny. Mainly the bronze sincro rings in the older tranny's if I remmember correctly. Some one else might have more info on this. Correct me if I'm wrong.

Here is some discussion on it here. http://tech.bentleypublishers.com/thread.jspa?forumID=40&threadID=6465

HELP!!!

gl4 and gl5 are ratings of transmission fluids.

I would recommend for your application (020 family VW transmission) 2 quarts of Redline MTL. It is synthetic and is great stuff, and also has the proper GL4 rating as required by your transmission.

Post by: Peter on December 04, 2004, 12:40:29 pm: Redline has an ATF for manual trans.called..D4-ATF(not just ATF) also it is rated as a gear oil GL4 ,which I use in my older subaru ...in my vw diesel I run with Honda manual tranny oil...very thin and almost like ATF...excelent shifting and no grinding
Title: trany fluid
Post by: fatmobile on December 05, 2004, 10:51:43 am: I've heard good things about syncromesh.
Over on the vortex, several people were saying they had good luck solving their second gear grind with it.
A cheap fix that worked great for them.
Anyone over here tried it?

Post by: fspGTD on December 12, 2004, 12:33:18 pm: I know of one knowledgeable VW transmission builder who is pretty adamant on putting brass syncros into all his VW 020 transmission rebuilds. The factory used brass syncros in most gears but moly coated steel in 2nd gear and sometimes 3rd gear as well. This tranny builder was of the opinion that the brass syncros had more friction than the moly coated steel ones, so it cut down or cured completely the potential "2nd gear crunch" problem. It's an interesting theory and "fix": http://www.qualityvwparts.com/trans.html

Post by: Dr. Diesel on December 12, 2004, 08:08:36 pm: here's a question Joe,
what oil should you use if you have a peloquin diff?
Title: What tranny fluid to use???
Post by: fspGTD on December 13, 2004, 04:19:10 am: Mr Peloquin recommends Redline MTL for his 020 torque sensing differential, IIRC. I also seem to recall his mentioning that it should be changed after a certain period of break-in. (Best ask him directly if you're planning on running one to make sure... no reason taking chances with such a nice and expensive glob o' gears.)
Title: What tranny fluid to use???
Post by: v8volvo on December 19, 2004, 12:07:55 pm: Yeah, when my tranny is cold second gear crunches bad, you cannot engage first unless stopped, and fifth is out. Once it's warm second is quick and smooth, first is OK if you double-clutch, and fifth is 50-50 it will go in OK if you wait in the gate for a sec before shifting in.

What is this "synchromesh"? How expensive is Redline MTL?
Title: What tranny fluid to use???
Post by: fspGTD on December 19, 2004, 01:34:16 pm: Redline generally runs about $8 per quart, with 2 quarts of "MTL" being required for an 020 5-speed. It is highly recommended.

I have not tried the "syncromesh" additive / fluid, so can't comment on that.

Post by: VWRacer on December 19, 2004, 01:41:48 pm: B&G Synchromesh was designed for limited slip rear ends back in the hot rod days. You can buy it from most any hot rod shop. Smelly, evil stuff... :lol:

Post by: VentoGTD on December 19, 2004, 03:35:41 pm: I'm using RedLine MT-90 gear oil and it's great.

Don't use any GL-5, it's bad for VW synchros. :wink:

Post by: srivett on December 19, 2004, 07:25:45 pm: I wish 4th gear was easier to get into. I get a heck of a wakeup call if I don't push the clutch in far enough when downshifting into 4th. All of my other gears are fine.

Title: syncromesh
Post by: fatmobile on December 19, 2004, 11:35:50 pm: I read about synchromesh over on the vortex so did a search and came up with:
http://forums.vwvortex.com/zerothread?&id=1720647&postid=17516512
I guess it is too thin but some people swear by it.
You might want to do some more searching around on the vortex ... and you might not.
