tranny juice

[thefitisgay]

im more focused towards the 568 cuz i have one but might as well include the rest

im asking for a little bit of the stats of the car cuz that dictates how hard the trans is used... and stuff like WHICH TRANS IT IS and how many miles are on it and the kind and weight of oil

mine is a 568 with about 150k on it... and i messed up and put penzoil 0 20 in it

i figure it cant be that terrible cuz its at least still oil in it but i have noticed it giveing me some issues

i wanna run a 0 tho cuz i heard these trannies like to lock up in extreme cold think i should run 0 40 instead of 0 30 cuz its got so many miles and is a little "looser" i did notice some shaft play when i replaced the front seal it seemed like alot but idk what it should be ya kno it wasnt extreme like a quarter inch tho

also think i messed mine up by runnin 0 20 in it for maybe 6000 miles? to be safe less than 10k

Synthetic motor oil will F up your synchros, either use a synthetic transmission oil or conventional motor oil.

[iangoround]

I've always run 5w-30 conventional in my transmissions. Even in cold NY winters, I've never had them lock up. If its REALLY cold out, the shifter has been a little stiff for the first half a mile but thats only if I don't let the car warm up for a few minutes first.

what about putting some of this stuff in there? http://www.schaefferoil.com/specialty/132.html

i imagine it would be good for the gears but idk about the other stuff and what about the motor i imagine it would be good for it but im iffy about running it through the turbo

and synchros come with a rebuild kit right?

[RoadWarrior222]

I think that's safe with the synchros, because some wet brake and clutch applications have moly additive lubes for them, in theory the moly bonds to the metal, doesn't mess up frictions.

I only use Redline MTL in MTX's...

KC article has some info!

[thefitisgay]

anyone else besides cindy offer the redline?

nothin personal ive just had correct address issues

i imagine i wouldnt find it at auto zone or walmart

and what about the axel hole caps... where would i find them? ya kno the red things

[black86glhs]

Summit Racing or JEG'S will have it.

[Clay]

Scheaffer makes good stuff. I wouldnt worry about using any of their products in your car.

[turbovanman²]

GM Synchromesh is synthetic and available at your local GM store, good stuff, :clap:

[Clay]

might want to be careful with Synchromesh in our trannys...... it contains a sulfur based EP (extreme pressure) additive that will eat yellow metals, ie our synchros!

[turbovanman²]

One guy has had issues and now its taboo?????? I've used it and never had an issue.

[Clay]

One guy? hell its a common issue, and not only in transmissions, but in my industry in gear boxes. They make transmission fluid with out these EP addatives. Thats why I used Redline MTL in my Jeeps AX-15 trans because it also has brass (yellow metal) synchros. The newer jeeps have the NV3500 trans, and can use synchromesh with out any issues.

[black86glhs]

On this same note, don't use GL-5 gear oil in a trans that calls for GL-4. It does the same thing. Ask any Hyundai trans guy and he can verify this.:nod:

[compshadow]

I put Mobil 1 in mine, is that OK?

AAAHH HA now i know why accents eat transmissions

keep it comin tho guys :thumb:

oh yea and mobil 1 is recomended for our trannies right? i mean why would the factory recomend something thats bad for our car

[boost geek]

GM Synchromesh is synthetic and available at your local GM store, good stuff, :clap:

That's what I always use, 2 litres synchromesh with 1 litre 80/90 gear oil. Don't knock it till you try it...:eyebrows:

That is why I used Mobil 1, I thought that is what the factory recommended for use in my 568.

GL4 still has the EP addative, but in MUCH smaller quantities. :thumb:

Your correct, but thankfully it doesn't chew up the syncro's.:D
I love it when people go GL-5 is the next step up from GL-4. ;)

[thefitisgay]

well of corse its a step up from 4 i mean when isnt 5 better than 4 :p

[RoadWarrior222]

Yup that's why I always top up my Dot-3 brake system with Dot-5 :eek:

[thefitisgay]

same reason why i use halogen headligh fluid in my sealed beams


i am interested in more info about the chromoly tho

[JuXsA]

I used royal purple MTF 80/90

[thefitisgay]

bump wheres the tranny experts chiming in??

[compshadow]

I asked an unmentionable person that sells rebuilt TD transmissions and he told me Synthetic
Mobil 1 is fine that is what he has always used with no issues??????????????
What does the factory recommend for a 568? Nobody knows, but everybody has an opinion.

[thefitisgay]

great input! keep it comin guys :thumb:
