i would summarize the differences but i am busy atm. someone else be a doll?  |
I've looked over those articles before and the main differences in the specs between them really aren't that big, just viscosity and flash points really.
It's the platform they're designed for and what additives they use in each, that's whats important to understand.
Porche's PDK which is a joint manufacturing project by both Porsche and ZF has 2 different types of Dual Clutch Transmissions depending on the car. Some models use a single oil circuit and some use dual oil circuits, which makes a huge difference in fluids that need to be used.
DCT/DSG (Getrag/BorgWarner) transmissions, from what I know, only use single oil circuits for all of their current models.
From my understand, again, someone correct me if I'm wrong.
Each transmission has the same basic twin clutch concept, but the internals and how it's implemented are whats different.
How the gears and clutches are lubricated, how much force and pressure is put on each component and how the oil circuit(s) utilize and distribute the fluid(s) for lubrication and whether it requires 1 or 2 types of fluid, just transmission fluid or transmission fluid AND gear oil.
Each fluid is specifically designed to withstand that specific twin clutch's demands. Some fluids might not be able to withstand the demands of a certain twin clutch and burn up the clutches or gears, some might be overkill and slow down the flow of the fluid, some might be fine for the clutches but not for the gears or vice versa.
So it's very important to understand the mechanics of these transmissions.
I personally don't know the mechanics behind the PDK (FFL-3) and that's why I exchanged it for FFL-2 (DSG).
DCT's that use confirmed compatable fluid are made by either BorgWarner or Getrag, respectively.
Volkswagen Group had the origional rights to implement a dual clutch transmission in a commercial production car. Porsche made the first DCT's in-house for Porsche and Audi racing applications in the 80's.
Also, so there isn't any confusion.
DSG is just Volkswagen's name for their DCT, like Mitsubishi's is called TC-SST, Ford's is called PowerShift and BMW's is called MDCT.

Yeah, there are a few credible people in the MR/Ralliart group that have been using FFL-2 for a while, Bryan@GST for example.

Mitsubishi isn't fucking around with warranty claims on their cars. Especially a blown motor or a $10,000 transmission.
If you're filing a warranty claim on something big and expensive, you better have the papers to back up your maitenance. Mitsubishi wants everything documented, they want service receipts from a Mitsubishi dealer or a certified shop for: Oil changes, transmission fluid changes using OEM fluid, diff fluid changes, etc.
You can NOT do it yourself, Mitsubishi doesn't think we are qualified to do our own maintenance. No matter how much experience we have.
But their Mitsu techs that want to put CVT fluid in our SST's and conventiol oil in our motors are just fine.
But what do you expect from a company whose automotive branch is going under in North America.
My warranty has long been out the window so I'm not going to worry about Mitsubishi.

Much appreciated.
If I was rich I would give you an award of some sort.  |
It's not a problem at all!
This stuff is just as important for us as it is for the MR owners.
It's totally worth the effort.
