I just used some Lucas Tranny Fix (additive) and it helped my problems. See my thread if you want to know what I'm talking about. https://ls1tech.com/forums/automatic...-slipping.html

 

If you want to contaminate your transmission in spite of what GM engineers, Tribologists, Chemical engineers and so on say then that's your choice. Not a smart choice, but a choice.

 

If you have some legitimate sources and studies for me to research, especially for your so-called "contamination" claims, then be my guest. All I know is I tried it and it helped my problems. By my count, something that helps a problem was worthwhile. I'd venture to say Lucas is not a sponsor for NASCAR and NHRA for having bunk products. The fact that the product I used helped my tranny issues is all I need to know. My choices may not be intelligent in your eyes, but the results speak for themselves.

 

Just really depends on the fluid really. Not all synthetic atfs are the same. Base oils used are different. Usually you will see 10-20 degrees in temp when switching to a good synthetic. I prefer Redline as they use Group V esters.

 

In the DEX VI camp, all DEX VI brands are sold using the exact same chemical additive package since only one company makes this package, that said, its proven that the walmart Supertech brand is just as good as the major labels so I just dumped mine and added 5qts of the walmart dex vi from walleworld @ $3.79/qt, Shifts great. AND NO, I dont use their motor oil, just the tranny fluid.

Like I said, my AT is a stocker with close to 80k.

It is in good shape, but true premium fluid. . . . Yeah, waste of cash.


I just used my standard issue ATF.


Worked fine before, I just kind of wondered this time.

 

They are sponsors for whoever because they pay for the priviledge, no other reason.
You forget one of the very basics....there is no such thing as mechanic in a bottle. You haven't "fixed" a thing, all you've done is mask some underlying issue.
And feel free to do your own homework...I'd recommend a look at some very basic SAE white papers on the subject.

 

Hmmmm, you guys will spend almost any amount of money on lubricants, additives etc for your engines, and then make a statement like this? Somehow, it just doesn't pass the common sense test. By this logic, you should be using any house brand motor oil, because it's "good enough" to keep your engine from seizing at an idle. Hell, you can probably do the same thing by filling your engine with Wesson oil as long as you don't drive the car.

 

Apparently you overlooked the wording of my post. I never said it FIXED anything, I'm not a transmission guru and I haven't tore down the tranny to see what if anything is actually damaged/worn/etc. I simply said it helped, and the symptoms that were there, aren't there anymore. Big deal if the tranny takes a dump on me anyway. I've got a warranty that will get me a new tranny for $100 deductible. Not saying I'm gonna purposely grenade it though

 

Yes and no. When talking about licensed Dexron VI the base oils and additive packages are pretty much spot on( they have to be for licensing). When talking about redline and amsoil, the base oils used are different, but additive packages follow the Dex VI spec. Redline makes D6 which is a Dex VI fluid. Redline only uses group V(some small amounts of IV as well) and Dex VI GM fluid was originally designed around a group III base oil. Different ways to arrive at a given spec.

 

I see, so high end fluid will make my AT last?

Compared to generic fluid. . . . . . . Opinions are like *** holes, everyone has one and they all stink.


From now on, I will use over priced Royal Purple and 7.99 a quart ATF. . . . .lol

 

Nobody said that you have to run an expensive ATF!? But if you want to be a smartass about it thats cool. There are two ways to look at this. Run a generic ATF and filter and change it out every 15-20k or run a high quality synthetic with a filter and run it twice as long. There is no magic oil. Sythetic atf does not oxidize as quickly as conventional atf. Its much more thermally stable.... And being that heat kills transmissions, a synthetic fluid makes sense when towing, offroading and the like. So at the end of the day there are a few ways you can increase your transmissions life. I have always run synthetic, bypass filtration, and a good quality cooler. Its overkill but I also never have transmission issues in 15 years so I think its safe to say it works.
