Heyo, so i recently bought an 09 Ralliart, and im thinking of getting a transmission fuid change or flush done. I have no idee if the fluid has ever been touched by previous owners, no records no nothing. So id like to know if its a good idea to have it flushed or changed. And also that my local garage would use Liqui Moly DCT 8100 fluid, i compared it with Castrol Transmax one that is identical to OEM, Diaqueen SSTF-1 and behold the specs are not the same. But i dont know if the specs for it are necessarily worse or better. I attached the two files so if someone could help me that would be greatly appreciated.

 

I'd like to know about this also, I am in Germany and getting stuff on the economy is ridiculous...

 

I decided to just go with The OEM Diaqueen, dont trust other fluids and the one that my garage was gonna use was slightly worse in specs, (viscosity at high/low temps) found a good price off a dude on kijiji for 7.5L fluid and filter

 

Cool, I am surprised nobody chimed in, wish more people would help on these matters. Those who have done this, not those who "heard that anything other than DiaQueen is a mistake."
