Transmission Fluid

Shit I really want to try this stuff but it’s currently unavailable on Amazon and if I order through tribodyn it’s 230ish bucks after shipping and taxes

 

At this moment, still available.

 

Weird. On mine it says currently unavailable could be because I’m from Canada.

 

top right hand corner of amazon.ca page, change country to usa.

Takes you to amazon.com

 

In what way? How does it change

 

Me, I run Redline. It doesn't get particularly cold in Houston. Not very often anyway. I never heard of this TriboDyn stuff. In other threads, I've heard it stated that you should NOT use GL-5 oils in the trans, even if it says it is also GL-4 compatible. And the TriboDyn product says GL-4/GL-5. People here seem to have good luck with it, so maybe it is fine. I'm no expert. But I think I will just stick with Redline.

 

It's fine, GL5 has a better shock rating from what I've seen, yes I did see some that talk about not using it but that was more transmission specific than a general statement on other sites. one that's rated for both is good to go, look at brake.fluid dot 3 vs 4 you can put 4 in 3 just fine I know it's not quite apples to apples.
also from personal experience redline pales in comparison to the feel I get with tribodyn even in hot weather (I do see 108f here) and spirited driving, yes it being good in the cold is a requirement for me as well.

Redline I always felt as.meh, even liked the Ford fluid better but that's my opinion.

 

This is good to hear. My car is waiting for me to pick it up after work with a fresh luk clutch and fidanza flywheel!! Got them to fill trans with tribodyn so I hope I’m not discouraged of how it performs.

 

Do you Tribodyn fans also use it in diff and transfer case? They appear to only make their limited slip fluids in TRI-EX not TRI-EX2. I think the TRI-EX doesn’t have ceramic and the TRI-EX2 does. Could you put limited slip additive into their TRI-EX2 gear oil?

 

I’ve got the tri-ex 2 so hopefully it treats my gears well. Don’t even know if I was supposed to go with either or.

 

You don't need the LSD version in the trans atleast on the speed 3.

@Sho what are you doing for the 6 with tribodyn this question is your area

 

I went ahead and set Tribodyn an email asking about limited slip. I actually got a call back, I was only expecting an email. So, I asked a couple more questions.

First, in regards to limited slip differentials, he said the EX2 is too slick, stick with the limited slip specific EX fluid for the differential.

I asked about the issue with using GL5 in GL4 applications. He said that GL5 is sometimes recommended against use in GL4 applications due to some GL5 oils causing problems with brass parts. But he said that shouldn't be a problem with theirs.

I asked what base oils they use. Not that I'm any expert. But, I know that PAOs and esters are considered "true synthetics". So I was surprised to hear him say they use Group III base oils. Where some people will debate whether Group III deserves the "synthetic" label or not. He didn't even say III+, but III+ isn't an official designation. So, maybe what they use is what others call III+, I don't know. But he claims the Group III base oil is irrelevant with their particular additives. I'm no chemist, so I can't really say. But it doesn't seem to add up to me that it is supposed to be the best oil but doesn't use the best base stock.

I asked him about fuel dilution with their engine oils. He first said it shouldn't be a problem with their engine oils. But then he said if I'm really concerned about it, I could drain the oil, let the fuel separate out since it doesn't stay mixed, skim off the fuel and then put the oil back!

I know that in the UOA thread, the Tribodyn had some of the best results. But, looking at sites like Bob Is The Oil Guy, there doesn't seem to be a lot of people in the world that think it is anything more than the proverbial snake oil. One Amazon reviewer, of course he's just one guy. But he said he tried it in his Vette. Rather than getting better milage and lower temperatures, he had poorer mileage and higher temperatures compared to the Mobile 1 he had been using.

If you guys have good luck with it, more power to you. But I think I will stick with what I know. Which is Redline for the gear oils, Penzoil for the engine oil.

 

I know this is an old post but I wanted to add my experience. At one point I put some Royal Purple 75W-90 and it was great. Then I had to do something with the transmission, can't remember what but I ended up changing the fluid at that time and what was immediately available was Valvoline Synthetic 75W-90 and I've regretted it since. Thanks to this port reminding me of how dissatisfied I am, I'm going to order some Royal Purple and change the Trans Fluid next time I'm under the car.

 

I used the standard 75w90 gear oil without any of the limited slip stuff without issue in the 6. Used it in the Trans, pto and rear diff

 

Can't PM anyone yet because I'm new here, but this might be a worthy clarification in case there are others a little confused with the 3 variants of Tribodyn 75w-90. (EX, EX w/ LS additive, EX2 w/ ceramic additive)

According to @Speedie6 the EX-2 (no LS additive, ceramic additive) is too slick for the differential (probably the same story for the PTO), but seems safe to use on the trans. @Sho since you don't use the version with LS additive, and the EX-2 is too slick for the diff, are you using the original EX version with all 3 parts?

That's the one I use

 

Update for this as the Summit Racing link is outdated and still left me confused ultimately.

TL: DR; TriboDyn Tri Ex 2 for transmissions, Tri Ex 1 for the differentials, LSDs, wet clutches, etc

I spoke with Mark Wheatley at TriboDyn, who owns the company, and he gave me the following information:

• The Summit Racing page that @Sho mentioned is TriboDyn Tri Ex 2
  • Summit no longer buys from TriboDyn as they sell direct now
  • Not marketed as Tri Ex 1 or 2 as it was before Tri Ex 1 was created
• Tri Ex 2
  • The original formula
  • Ceramic included
  • Do NOT use Tri Ex 2 in an LSD or anything with a wet clutch, that's what Tri Ex (1) is for
• Tri Ex (1)
  • Created after the original Tri Ex 2
  • Originally for Australia as they needed a cheaper priced option that still beat the competition
  • All Tri Ex (1) oil has the friction modifier in it
• Film Strength
  • Mobile 1: ~6,000psi
  • Driven: ~14,000psi
  • Amzoil: ~87,000psi
  • Tribodyn: ~304,000psi
• Other claims (for their regular motor oil weights)
  • TriboDyn to increase fuel economy by 5-10%
  • 2-4hp increase potentially
    • Mark simply asked "How much would you pay for 2 more horsepower? What about 4?"

You say EX-2 for the gearbox but EX-1 for the diff, but in transaxles like ours, the gear oil is also the diff fluid. I used to run the old no-LSD additive fluid from Sho's old link, (apparently the same as Tri-EX 2, but I don't remember anything about ceramic additive being in that old fluid when I bought it last time).

I'm wondering if we should use Tri-EX (1) despite it having the friction modifier in it. If Tri-EX 2 is exactly the same as the old no-LSD-additive Tribodyn, why does it specifically say that it should NOT be used with wet clutch/LSD?
From my memory the old 75w-90 without the LSD additive did not have such a loud, bold, red letters warning to not use it in LSD applications on it like the EX-2 has on the Tribodyn website.

 

brado has a ms6 so when he says diff he means rear diff. also the transaxle on the ms6 is not limited slip.

 

Ah, copy that. Makes sense.

If the EX-2 is truly the same as the old non-LSD-additive 75w-90, then in theory that would be the one to run in an ms3 and the one that is currently in my gearbox. I am still wary/doubtful that it is the case though as the Tribodyn website does have that huge bold red letters warning saying not to use it in anything with an LSD. At the same time, I have heard that using fluid with LSD additives and/or friction modifiers like the EX (1) causes noises and grinding within the diff, particularly when turning or at low speeds, and that those fluids are generally not as good for the transmissions.
It seems like with the info here the question still remains unanswered on the ms3 side of things.
