Will do, but it's ony 2nd gear.

As Hans and Franz used to say, "You can listen to me now or believe me later!" I have written too much about this issue to restate it any further than that.

Charles,

Checked the clutch and all looks good. I did however notice something. 2nd gear grinds only after the tranny is warmed up, I tested it and reved to 7K and shifted while tranny was cold and it didn't grind, just a little notchy but not to bad. I did this three times with the same result. I know not to rev a cold engine but I just had to try. Could it be that the fluid in there is bad? I changed it last October at the dealer. I have an appointment on the 14th for a tranny drop with the dealer. I guess my options are to have them inspect it or maybe try a different weight fluid. What do you think? I have some RP maxgear lying around or should I try something else?

When it comes to fluid use JaxRX8 is the flat-out smartest guy I know on the issue but he and I slightly differ in our opinions. I mention this because I would like to believe everyone has read, and respects as I do, his opinions on just which fluids we should be using. That said, I have tried a few of the "exotic" fluids(like RedLine and Royal Purple) and I always end up right back using my tried-and-true Mobil1, 75W90. I should warn you that it is a GL-5, as opposed to a GL-4, and it is said to not be suggested for our transmissions. This is the issue Jack and I slightly disagree on, which is only to say that I am not nearly as concerned as he is.

Now do you think that my hunch about the oil in the tranny is true?

Charles R. Hill

iTrader: (7)

It's possible. What are you using and how many miles/months are on it?

devildog1679

Oem Fluid, changed in November with 6K miles on it. I just find it weird that it doesn't grind when cold.

WILL YOU PEOPLE PLEASE QUIT SPREADING THIS OUTRIGHT MISTRUTH

I was going to try RP Maxgear on Saturday but that would just hide an existing problem, sooner or later it will re-surface. So I'm just going to the dealer, if they refuse to cover it I'll fight them tooth and nail.

way to go ray... pissin people off! :D

my car is in the dealer right now with the transmission apart. 47k 2004 Stock fluids.

Found: torn 2nd synchro, torn second gear, broken 1-2 shift fork.

Trying to deny warranty because thats a sign of "abuse". And because of my mods.. midpipe, intake, pullies, heavy appearance mods. I will find out tomorrow what the status is on whether or not its going to be warrantied. What to do?

Team just likes to "eff" with me 'cuz we are friends. He may have a point but I have heard all sorts of rationale for one view versus another and can only tell you guys what has worked for me, specifically. I figure the fairest thing to do when discussing differences of opinion is to at least acknowledge another opinion/point-of-view/concern in the discussion. Team may not be much aware of opinions other than his own.:

The good news is that I am one of the few who can take criticism and not make it personal.

devildog1679

My manual says to use GL-4 or GL-5. I have a 2005.

Has anyone switched their brake / clutch fluid over to ATE SL.6?

It is half the viscosity of ATE Super Blue and is supposed to be better for systems with DSC and anti-lock brakes. Quicker reaction time because it can flow into smaller areas faster than the thicker fluid.

I wonder if this would help our clutch since it is hydraulic and uses the same fluid from the master cylinder.

NEED GL-4 80/90, 90, 75/90 HYPOID GEAR OIL ADVISE RECOMMENDATIONS:

so my '07 as of 2k miles went for a full royal purple treatment if i was to experiment with synthetics at all. ever since day one up til now of the fluid change, the synchros has been nowhere near perfect like factory. i changed both trans and diff 75/90 and 85/140 at the same time.

the royal purps has been nothing but notchy and chatters from first-to-second gear shifts. also in fif gear. and a hint of gear whine on cruise in 6th gear....
not a happy camper here. it only performs well when warm, but its unbearable for a street car that has to chance gear grinds on every morning start up drives.WTF!

so help me out. i'd like to possibly find straight 90 weight for the trans with a GL-4 grade... or whatever thatsgrat oil specific w/o any of that diff additive bullshi* in it.
no more synthetic experimenting for me...and the gear chatter stopped only to find out the royal purps burn up about 1/2 qt in the duration of 6-7k miles! i noticed this as i filled in "lucas oil stabilizer" to thicken that thin *** synthetic gear oil sucka up.
nd there's always that lucas 80/90 gear oil which is pretty thick... though i'm not sure about the GL-5 additives in there or not.

so is there any (hypoid???) trans specific 80/90 or straight 90 that i can find, and does valvoline carry straight 90 weight gear oil??? pepboys/kragen/autozone...which to go for conventional stuff but the best brands.
like i said, i'd like to see if valvoline has any gear oil available. i trust that brand, and i've searched everywhere from honda dealership to mazda to nissan with no luck. but was sent to a mom/pop shop that carries STA-LUBE 85/90 GL-4 specific which i bought just today to fill my dads 350Z. but its a crappy brand, which is ok for a slow driver like my pops in his 350z, but prefer a high quality conventional for me to at minimum match factory quality...

-any good conventional brands anyone can recommend here?

thanks,
troch

auto oil must contain some secret ingredient that instantly turns people into complete idiots ...

Yeah, it's called marketing and people mis-applying a given fluid for a given use. Lemme ask again, Mark; What are you using in your street-driven RX-8?

There is sometimes a strong similarity between engine/driveline fluids and ignition systems that are both engineered for racing use. Might you know what that similarity is? Anybody?

This is why I ask about your street-driven, as opposed to your track-only, RX-8.

TrochoidMagic

c'mon man, stop trippin' like that. i know, i know. i knew it was coming when i was gonna mess around with it, and had a feeling i may be misapplying this stuff.

i'd have to admit, other than honda trans which pretty much uses motor oil, i'm challenged when finding a gear oil and diff lube. and with the grade so hard to find, its also confusing if we can really get away with something containing GL-5 additives in it.

but c'mon team, its not like i really didn't try hard dude. not even mazda nor honda carries this **** in stock. i ended up finding something like STA-LUBE 85/90 which don't sound like a popular brand. but sure as hell useable...

now i just wanna find some nice thick 90wt conventional stuff... its so hard to find. who has them is all the help i'm askin for. is it too much?

whatever info oyou can provide to make my life easier would be great.

TrochoidMagic

hmm... i may have mistaken if that was for me.

but either way, anybody's help would be appreciated.

and to say the truth, i'm not a huge fan of synthetics. as long as its the highest available grade for the specified application, just like SM grade with motor oil, i'd be fine with whatever recommendations on the most populaar/ easily accessible transmission gear oil and diff oil.

thanks,
troch

its a big misunderstood argument. I use RP max gear. Lots use redline. Lots use Castrol. noone actually knows which is best for the rx8 tranny because noone has applied a specific fluid for long enough to know. Sure, teamrx8 uses a specific kind in his track car and im sure a different kind in his street car, but i dont see anyone with any PROOF of why a certain type is better. do you??

I noticed the shifts are better when I switched over to the ATE SL.6 Brake fluid.

The clutch disengages quicker and more consistantly.

I flushed the whole system with a liter and a half from the ATE Super Blue. No bubbles were seen during the entire flush into a bleeder bag. So that rules out that it needed to be bled. The Super Blue fluid was bled a few months ago so yes it is wasteful but I feel it was worth it. I purchased the ATE SL.6 from Tirerack.
