Are you serious?

First of all, this is not a scientific Forum, but feel free to Peer Review and make comments based upon your chemistry experience and academics.

Secondly, in any scientific publication, an author of a paper has the right to quote himself from another paper or to make references to his previous papers, space permitting of course.

You pulled me back in!

This is not a science publication, nor are you a scientist that has shown any viable research.

By quoting yourself you did nothing but waste the reader's time by forcing him or her to click on a link to something that you could've posted in this thread...ridiculous!

I feel like I'm teaching you now, Professor MolaKule

Edit, I also find it hilarious that you started another thread just so you can quote yourself here! That sounds like an enormous waste of time to me!

You crack me up. Molecule has forgotten more about lubrication engineering than most of us will ever know,then you question trav's immeasurable experience in the real world of auto mechanics.
These 2 guys are such a great asset to this forum yet you call them out as though you think you've got one up on them. Sheer absurdity.
You continue to post and make yourself look worse with each one.
I do thank you though,this thread made me laugh,actually you made me laugh.
Quit while your only this far behind,the lap cars are coming again,so you might as well move over for them.

I don't claim to be anything I'm not, Professor MolaKule.
Like I said previously, you may or may not be right about it, but who knows since I have no idea where you got your information from.

LOOK! I just quoted myself!

Like I said, I dont claim to be or know anything on this, just merely did my own research and came to a conclusion that I posted here.
Furthermore, I did not engage in a discussion about this with Trav, MolaKule is a different story and only because of the pathetic way he attempted to back up his point. ie, quoting a thread you started just to bolster an argument in another thread.

Ive been on this forum for a couple of years, I know who is who and it's of no consequence to me. You can kiss up to who you want, but that's not my style.

I gave an opinion and it is merely an opinion, those guys chose to make it a personal thing with me.
I post what I have to say, people are welcome to have their own opinion and it should have nothing to do with me.
This is an open discussion on a forum, I'm not here to be graded on my performance or knowledge on anything. I welcome educated discussions on things, but it shouldnt have anything to do with me as a poster and my knowledge... unless I state as such.

BTW, I don't see how any of this helps the OP.

It's OK, you're a good guy, Trav.

You got that right i "ratted you out". Post something like that again to me and i will take it to the owner. Keep it civilized or move on.
People have been banned for a lot less than that.

You posted..

Calling someone out for passing bad info when the guy was 100% correct? Sorry your the one making the mistakes here.

If you notice, I never quoted the person or used their name.

I also did amend my original thought to state that it's my opinion and NOT fact:

Ive stated this several times since my original post, which I admit I shouldve included that it's JUST MY OPINION!

So, keep quoting my original post, thus making me repeat myself.

Ummmmmmmmm . . . . . . if it were my Buick, I'd drop the pan, change the filter and clean the pan good, (check how much of the famous "grey goo" is in the bottom and clearn well). Then I would reinstall the pan and add the proper amount of DexIII/M fluid and drive it for a while. Then I would pull a few quarts out via filler tube with suction pump and replace. Drive a while, enjoy the journey, listen to the radio, visit old friends, and change some more fluid. Do this till you've run say, four gallons of fluid through transmission. If the fluid change is going to fix transmission, it will be fixed. If not, it will stay broken. I would still say it's worth s shot as the most you'll be out is the price of the filter and fluid, but I do not believe new fluid is going to "destroy" your transmission. Good luck and keep us posted on results.

I have a buick with 185k on the clock, the transmission fluid has NEVER been changed, it is a brownish color.

The car drives fine, except for after about 30 minutes of driving the transmission starts shifting hard.


Should I change this fluid and add a bottle of lucas transfix to the mix to keep it a little thicker to hopefully avoid slipping, or should I leave it be and let it die a natural death instead of trying to fix it this late in the game?

It bothers me a little because I have even heard mechanics say to leave it be?


Thanks!


Sorry about the detour, but you should be able to do a drain and refill with a filter replacement and use any DexronIII or VI off the shelf.


If it were mine, I would start off with something like Supertech Dex/Merc or MAxlife and let it do a slow clean, and then maybe another drain and fill at 10,000 miles or until the fluid starts clearing up.

I would not add Lucas or any other additive.

Good luck and let us know how it's working out.

Right! This pretty much what I'm doing with my 87 Ciera.

Be gentle, and NO flush! Ive heard some positive things about fluid exchangers, but I say play it safe, a little at a time.

I see nothing in that thread of value to your arguments. Dex 6 > dex 3.

Really? A couple of posts on page 2 talking about some negatives. There are some positives discussed as well, but I all I need is one negative to scare me... doesn't take much, FWD transmission rebuilds are $$$$!
Some other forums with the same deal, some positives as well as negatives.

With a high mileage FF car (OP's car), I would not mess with Dev VI. I also read that it's thinner than Dex III, but I also read that Dex III shears faster and ends up becoming thinner like Dex VI.... like I said, lots of contradiction out there, certainly enough to scare me.

DexronVI is 1.5 cSt lower than DexronIII so it won't matter.

Even if DexronVI is slightly lower in viscosity going in, it shears way less than what the DexronIII viscosity would be after about 30k miles.

I have the same transmission as the guy with the Pontiac in that thread in my buick century. It's a well documented issue of firm shifting it has and his fluid had nothing to do with it.

I understand that transmissions are picky but dex 6 is not some universal product. Dex 6 supercedes dex 3 and since it's more stable over time I'd rather have the fluid that won't shear down as much.

But, there was also another post of a guy who posted this:

That among some other stuff made me nervous.

For me personally, my car is an '87 and is spec'd for Dex II and I think that is just too far of a leap for me to do a Dex VI fill.
Haha, I don't even want to use the Dex/Merc stuff. I would however feel better if Dex III was available; but ultimately, I would use Dex II if it was still around!

The things I read on the shearing of the fluids was interesting. I read another forum of a guy saying that because of Dex VI being thinner, it would mess fluid pressures or something and that the thinner fluid would be more prone to internal leaks... probably a bunch of bologna, but enough to make me think.

You should see what's out there!! In one thread one guy says, use it and then another says dont and then the next guy says use it and so on and so forth.

Yep, definatley poo-poo gaga.

Dex/Merc is the same formulation which covered earlier GM and Ford transmissions.

Do you know that for fact?
Have you seen the blend cards for a start?

That is a great question!
...because Ive read that the "one size fits all" fluids can vary between brands.


Seeing as I don't have much of a choice since Dex II and Dex III are not available, I went with Castrol Dex/Merc because they are a pretty reputable company and are reasonably priced (1 gallon costs $17.99 at my local Autozone).

I didn't want to mess with the Valvoline Maxlife stuff only because I didn't want to mix a synthetic oil with my FF Dex II... I'm a "Nervous Nelly" when it comes to transmissions.
