From the owner of Kozmic; the world's leading Getrag DCT470 transmission specialist
"I have been saying this for years. I have dealt with every single fluid available for the SST. I only recommend one. Genuine OEM, even when I suspect that other "over the counter" fluids may be close to identical. However the DCT470 does not like the FFL family of fluids. By the numbers. 1. The OEM's have specific specifications that fluid delivered to them must meet. Over the counter fluids have no such requirement, and as such the fluid may not be identical, even if it is made by the same company for the same application. 2. The SST operates in a "gain" mode most of the time. The slip rate vs pressure rate that the transmission uses to control this slip is hard programmed, and the transmission tends to react poorly to anything that changes the dynamic friction rating of the clutches, even if it INCREASES it. (Dynamic friction refers to the state where the clutches are engaged, but in a controlled slip state, aka as "normal" mode for the SST) 3. Wet clutch friction properties are highly susceptible to change with different fluid properties due to the friction maerial absorbing the fluid. Even the glue used to adhere the friction paper to the plate effects the properties of the clutch. This change may be permanent if left for a long enough period of time. Eric"

Dude...we know that KOZMIC is the world record holder...can you please stop and maybe read your post AGAIN... you're quoting with regards to FFL series fluids...which are totally different from the OEM fluid (Castrol BOT 341).
I guess you don't understand what Castrol BOT341 is. The fluid i'm referring to is BOT341. which are REBRANDED as DIA-QUEEN, POWERSHIFT, TRANSMAX DUAL, oh...and BOT341 because guess what...the 6DCT450/470 SST gearbox is not unique to Mitsubishi...other car companies use it as well. I guess Mitsubishi calls Castrol up because they're tight like that....and says "hey Castrol please add that lil something extra in the BOT341 so we can call it DIA-QUEEN & charge exorbitant prices...even though the exact same Getrag gearbox is found in other cars...cool thanks bye..." *click*
Instead of blindly quoting something ...maybe do your homework on the product before you go on a bashing spree Please stop replying to this thread if you wish to keep bashing a post which was made to simply share an experience... not cool
CASTROL BOT 341 is rebranded as DIA-QUEEN. There is only one type of BOT341. If there was a difference it will be given a different code like BOT342. How ironic that Ford themselves who make the Getrag Gearbox lists it as Castrol BOT341 along with their own corresponding ford part number.
Or do you believe that...Mitsubishi makes the Dia-Queen for Castrol who then calls it BOT 341...before they sell it off to other car manufacturers *insert X-Files music here*
I think you've made your point... you know more than me Can you please go bash someone elses post.
"Jack, owner of Jacks Transmissions, also owns a vehicle with an SST that is driven everyday. Jack has spent a lot of time and money trying to find a cheaper alternative to the Mitsubishi DiaQueen fluid. We have tried Castrol, Ebay fluids, and Pentosin. None allow the SST to operate as it should and we have found that the Mitsubishi fluid truly is the best."

Okay guy.... quote away. You can ignore someone that actually used to work for Castrol ... and i'll keep using rebranded volvo fluid & blow my transmission up & you can sleep better knowing your non stop quoting "told me so" Agree to Disagree.
You do know the difference between 6DCT450 & the 6DCT470 is just the clutch rating right?...DCT470 stands for the clutches & rating in the transmission (470Nm) which is 20Nm (14.8 lb.ft) more that 450Nm clutches. You can generate 20Nm by turning a wrench with your hand. Oh and since you love quoting kozmic...
They use OEM BOT 341 or "dia-queen" in the transmissions which have the HP10R kits which have a torque rating of around 450lb.ft or 620Nm. Are you now saying that the same BOT341 suddenly doesn't work below 470Nm hence they're totally different transmissions?
The DCT450 was built by Getrag Ford.....the DCT470 was not..
zeRep
Okay...then who built the Getrag 6DCT470? This is taken from GETRAG.... Do you even know who GETRAG is?
FORD OWNS GETRAG! THEY Build everything made by GETRAG....
All They did was change the clutches from 450 to 470 in the EXACT SAME 6DCT450 & flashed the TCU for S-Sport for the EVO X.
Please just stop....you're hurting my brain with your stupidity.
You've just proven why I say...it's important to do YOUR Homework before you just quote randomly
Apologies....Sorry zeRep85RA for that last comment about stupidity.
The EVO X SST Gearbox is made by FORD-Getrag & uses the the same 6dct format. Go and look under your EVOX SST & you'll Ford Getrag stamped on the block but the Clutches are different capacities. Please again do proper research before you say Getrag-FORD didn't make the 6DCT470.
Anyway this doesnt take away from the fact that Castrol BOT341 is universal between all the 6DCT450/470 gearboxes and is rebranded by other Car Manufacturers that use the same 6DCT450/470 in their vehicles. I've said this before. This was a post about my experience...yet you contintue to bash it in order to prove that you're right.
So once again please agree to disagree & move on.
Can you please go bash someone elses post.
