T-56 Dexron III What fluid are you guys using in your T-56s?
I know they dont make Dexron III anymore. so I wonder what is the best CHoice to use..
I havent used this, but is Dexron VI ok to use??
I dont want no answers like " yes, it exceeds Dexron III, so it myst be fine"..
because when they made Dexron VI, they probably had Auto transmissions in mind..
I wonder what was the last year they made T-56s and what they still used.. Like what does the CTS-V use? but then again, I dont think they're running T-56s anymore, either..
Does anyone know whats the Best ATF to use in a Built T-56??

Im a manager at a auto parts store and they still do make dextron III. lets just say you go to NAPA and pick up a few quarts of part #75-200 or you can pick it up at any auto parts store.

Thanks for the help..
But I am still curious if we can run any other ATF in our cars, if they say they exceed Dexron III...
etc..

I haven't done any research, but I next time I need a tranny fill for the T56 it will be with Dexron IV.
The reason it's called Dexron is to assure people that it's backwards compatible. Otherwise a new oil would be called something else.
I can't imagine D4 has omitted anything that D3 had. Or that D4 has added anything harmful that D3 did not have.
This is the logic I'm going with even though I don't know **** about it.

dex IV is backwards compatible with III but im not sure if its full syn,if so i wouldnt use it if your t56 is equipped with the paper blocker rings,only use with carbon fiber rings.

I had carbon blocker rings when I rebuilt the T56.. But the paper and carbon blocker rings look very similar, if not identical from physical appearance, at least thats how they looked after ATF was covering them..

thats the royal purple stuff. the one i bought is pennzoil the same oil GM uses, theres is rebadged pennzoil as well. it really made my car shift smooth. i went from mobil 1 dex III to regular dex III (it was actaully smoother then full syn) then syncromesh about $10 a quart and this made a very big differance especially in the mornings

They look like a flat charcoal colour. (the carbon ones)..
The "paper" ones looked very similar to me. (unless my trans had been rebuilt before?) But I doubt that, I bought the car at 56k miles, at a dealer and no history of rebuilt trans.. Besides, everything else in the T-56 looked stock..

I wanna know what type of fluid people are running in their 700+rwhp capable T-56s...
Dex III is fine, but is there a better Dex III out there for a more race built T-56?
The car is a D.D. although these days its not seeing as much mileage as it used to...
The car gets drag raced, but also occasional road racing as well..
Car makes near 500rwhp now and maybe a bit more in the near future..
I expect the car to maybe make 700+RWHP in the future...
