The time has come FINALLY, after putting back in the tranny. I'm in need of a VERY good kind of Tranny fluid. I don't know what to look for but I want as close to the best as I can get. Any suggestions?

From Jacks Transmissions: http://www.jackstransmissions.com/faq.phpQ: What kind of gear oil do you recommend?
A: For our DSM and 3S transmission rebuilds we recommend factory Mitsubishi 6-speed manual transmission gear oil from the 2005 Mitsubishi EVO MR. (Part number mz313376). This is the best oil to use as it has the perfect blend of friction modifiers to keep the tranny shifting smoothly and prevent gear failure. Please make sure you use the proper amount as specified in your owners manual (typically 2.4 Qts.) Gear oil choice is very important and varies based on preloads and synchro blocker ring design, therefore it is strongly recommended that you stick with this fluid for our transmissions. If you are unable to locate Mitsubishi MR 6-speed oil from the Mitsubishi dealer, Redline Heavyweight Shockproof 50/50 mixed with Valvoline 80W-90 gear oil will also work just as well. For transfer cases and rear ends, use Redline Heavyweight Shockproof ONLY. It is especially important to use only Redline Heavyweight Shockproof fluid or Mitsubishi dealer t-case fluid in EVO transfer cases. DO NOT use Synchromesh, BG Synchroshift I or II, or Royal Purple. These fluids will destroy synchros and gears and void your warranty! THESE ARE THE ONLY FLUIDS WE HAVE EXPERIENCE WITH. If you ask us "Will xyz fluid be okay?" we won't have an answer for you.
From T.R.E.: http://www.teamrip.com/manual_transmission_gear_oil_recommendation_info.htmlGL-4 Gear Oils
We strongly recommend using a GL-4 spec transmission oil in the Mitsubishi manual transmissions. This oil offers good protection for the gears and bearings against wear out. Do not use any oil that has a GL-5 rating in the transmission, for these oils will not give the best shift quality because the GL-5 rating might end up being too slippery for the synchronizers to be effective for high rpm shifts.
There are several GL-4 gear oils on the market for you to choose from. Redline MTL is excellent for daily drivers & weekend warriors and those who live in cold climates while Redline MT-90 is recommended for road racing type service. Both of these oils have proven themselves as a worthy oil for those who want to shift fast, yet are also looking for long service life from their transmission. There are concerns about using Redline's Shockproof type gear oils inside manual transmissions. While this is truly an excellent product, it has been found that the heavy paraffin-like particles are quickly centrifuged out of the oil and build up inside the center diff housing and around the synchronizers and inside of the gearshafts. After several oil changes this build up may block oiling passages inside the gearshafts that lubricate the needle bearings and can reduce the overall effectiveness of the synchronizers, leading to poor shift quality. Therefore we do not suggest using Shockproof in the transmission unless the transmission is to be serviced often or a dog box.
Another transmission oil that works very well is Diaqueen Super Multi part # MZ313376 and it available at the Mitsubishi dealer. Mitsubishi strictly specifies this oil for the EVO-MR 6 speed transmission but it can be used in the 5 speeds, it works and we recommend that you use it if you can't find Redline MTL or MT-90.
Synchromesh/Synchroshift gear oils
While it has been found that the Synchromesh/Synchroshift type oils can sometimes improve the effectiveness of the synchronizers, allowing for faster shifts at higher rpms, this oil does not have enough film strength to ensure the longest gear and bearing for the Mitsubishi transmissions that lives behind a high torque engine. Synchromesh/shift type oils are used in transmissions that are found in low torque applications that don't ask much from the oil in regards of film strength. If you have a weak synchro, you may want to try the “Synchromesh /shift” type oils. However, it is our recommendation that you use the proper GL rating that the transmission was designed to use. Check your owner's manual for this information. From Shepherd Transmissions Inc.: http://www.sheptrans.com/faqs/index.htmWhat gear oil should I use?
There are several gear oils that will work depending on horsepower or intended use. For most transmissions we recommend Redline MT90 or Pennzoil Synchromesh. For drag use or high horsepower cars please contact us. Please let us know if you need any Redline gear oil.

QUESTION:
I have Royal Purple 75w-90 gear oil. Im getting my clutch done soon, it says it meets GL-4 and GL-5 requirments. BUT i read that GL-5 eats away at the synchros...

Any Hypoid Tranny/Gear Oil will errode the Brass Synchros that is why it is important to stay away for such lubricants.
I use the MT90 as I do not drive the car in winter. The MTL is a "Lighter viscosity Manual Transmission" Fluid so prefered for years around.
I prefer to put the RedLine Heavy Shockproof in the XCase and Rear End.
GM Synchromesh, Royal Purpule or AMSOIL also have excellent products.
Hope this helps.

stupid question but: Do you know the chemical in the GL-5 that would erode the brass synchros as appose to the GL-4 chemical compounds?
IT says on the bottle:
"Meets Performance Requirments of API GL-4 and GL-5"
"Great for Manual Transmissions Requiring GL-4 or GL-5 Fluids"
"Contains limited split additive"
Any other feedback? Has anyone use this Royal Purple in their tranny??

Well since it reads:
"Meets Performance Requirments of API GL-4 and GL-5"
"Great for Manual Transmissions Requiring GL-4 or GL-5 Fluids"
Wouldn't it be ok? I mean, if they [royal purple] know the sulfur destroys the brass synchros in the GL-4 tranny, wouldnt they want to fix that? Im sure they figured out a way to fix it since it states it meets both GL4/GL5 requirments? I mean products are always updated and improved. What you think...
I went on the website and found pretty much the same information. Im going to call Royal Purple later today and try to get some more information. Its hard to find good solid information on this stuff...
I've read no no, because of people saying stay away from GL5 (even though this says it meets both) and others saying Yes Yes, after using it, "day and night difference" is what i read the most...
Im just angry because i spent almost $80 on 3 quarts of this stuff...
One other word:
When small/large business websites state which oil to use: can vastly depend on the fact they might be getting a deal by promoting their products. Ever hear of the Dr. scandals going away on free vacations for writing prescriptions for their products? It happens... Not to say that any of the above mentioned have done that, but i'm always sceptical. This is why i would actually like to find some scientific testing of the oils. The Truth Is Out There.....Somewhere

IIRC Royal Purpule have two different MT Fluid; one that is more apropriate for our Trannys.
Let us know your findings.

If your running BG syncroshift, MTL, or GM syncromesh straight, transmission won't last too long as these are too thin. They should be mixed with thicker fluid. I stay away from MTL and MT 90. Prefer regular 75w90 GL4 gear oil instead. I do my own blends now, and have been sticking with the same formula for a while  Search around and everyone has a different opinion. The best thing that will make your transmission shift smooth, is a good transmission and properly adjusted clutch.

OK, so i just got off the phone with a REP from Royal Purple, and he said that it will be fine. I mentioned that im getting different answers on the message boards of people saying it will erode the brass synchros...he said that's because we dont understand the "special additives" that they put into so its able to meet both requirments and wont erode any soft metals.
**The special additive is most likely a updated version that i mention above**

the GM syncromesh is $15/lt at the dealership and is sold out most of the time. You can talk them down from that $15 price, I've had it as cheap as $8/L. they did have a syncromesh for $8/lt.. the syncromesh friction modifier was $15/lt.. hope you got the right one .. they changed the packaging

Right, "regular" 75w90 GL4 gear oil, not redline synthetic. Isn't Mt-90 a full synthetic ? Anyways haven't tried the heavy duty Redline products, though I would try them before going to MTL or MT-90. Over the 10 years of driving DSM's I found MTL/MT-90 to be crap. They work fine for small horsepower applications. JMHO and personal experience. There's castrol synthetic 75w90, MT-90, Amsoil, and other 75w90 GL4 gear oils too. I've tried everything, I'll stick with my motormaster blue bottle  , and special blend now. Don't want to go into too much details, but just stating what works fine for me with the power I make, and no broken internals yet on a stock trans. Feel free to use all the MT-90 you wish , everyone has a different opinion. I know it sounds weird, but anytime I used a straight synthetic, it just never shifted the best.

Ya, I believe the MT-90 is a full synthetic but what kind of difference does that make vs a reg fluid? I thought the whole purpose of synthetics were better protection, less breakdown, etc, etc? Or, just in your experience straight synthetic never shifted as well?
I know, everyones got their own opinion on fluids. Jon @ TRE built my tranny & MT-90 is what he liked/recommended, so figured thats what I should run.

Yep I know it contradicts the fact about running straight synthetic. Its just what I experienced over the years, so I stay away from it now. Technically yes it should work better than conventional oil. Though I've put on enough miles and been through enough transmisions to know what works better, for me atleast I know Jon at Tre recommends it, but it seems like every year the top builders change their mind as to what works the best. I remember years ago a post from Shep that he uses 50/50 mix of BG II and Amsoil when he was running 8's, similar to what I use now, except instead of Amsoil I use the motomaster stuff. I tried it back then and really liked it, still using it. Now I'm pretty sure that the recommendation is something else.

Yep for the winter season, I would definately do a mix with BG2. I tried the motomaster full synthetic straight as well and didn't like it at all.
I ended up doing the 50/50 mix when I was driving the car all year round and it shifted smooth on winter start ups.
Last year all my low 11 second passes were on BGII/motormaster blue.
The trans shifted amazing all year, until I was doing back to back runs and ripped the teeth off the galant 1st gear.

Joshua: Word of warning, I would bet you $100 that guy on the phone knows less about oil than you do, and it sounds like you don't know much! He is a salesman and will tell you anything! Talking about "special additives" is a load of BS. Ask him what the additive is so that you can make an informed decision.
GL-5 is a specification and does not dictate that Sulphur is used, but MOST GL-5 oils use sulphur in order to meet the spec.
If you are unsure, or uncomfortable try to return it.

Found this on Royal Purples FAQ:
My vehicle’s transmission specifies an API GL-4 gear oil. Can I use Max-Gear?
Yes. Max-Gear possesses both API GL-5 and GL-4 certification. Max-Gear is formulated with Royal Purple’s proprietary, Synslide additive technology to provide the exceptional film strength necessary for GL-5 applications, yet it is noncorrosive to soft metals found in manual transmissions that specify a GL-4 rated lubricant.
I also found this on the site:
Synthetic oils enable Royal Purple to make superior lubricants, but it is Royal Purple's advanced Synslide additive technology that gives Royal Puprle's EP lubricants their amazing performance advantages. Synslide additive technology truly is beyond synthetic.
Synslide additive technology, Royal Purple's tough, EP lubricating film, provides maximum protection under boundary lubrication conditions typically caused by heavily loaded, slow speed and / or shock load conditions. This tenacious, slippery film significantly improves lubrication and reduces wear by increasing the oil film thickness and toughness, which helps to prevent metal-to-metal contact in gears and bearings.
Synslide additive technology is noncorrosive to gears and bearings, including case-hardened gears that are easily pitted by conventional sulfur-phosphorus EP oils. Synslide additive technology displaces water from metal surfaces and excels in protecting equipment in wet environments. It also fortifies the oil against the detrimental effects of heat, which causes oil to oxidize.

What type of oil should go in the transfer case and rear diff?
I read it should be a GL5 grade?

That didnt answer my question: Should GL-5 spec be going into the transfer case/read diff...
And why didnt it work well in ur 1g, this is going into a 2g and i've read good things about it as well...
