What is the tranmission fuild used in 2020 peugeot expert long with eat8 speed. This is a Aisin made tranmission however geelong dealership qouted :
"MOBIL ATF 4HP20/AL" fluid that is for zf tranmissions? I BELIEVE THIS IS REALLY WRONG. Can somebody who has changed the fluid share what they used. I have a volvo with same tranny but 6 speed, that uses completely different fluid than what I expected in the quote.
 
The Eat8 is a version of the Aisin F8FXX and is used in several makes including Mini and Lexus. It will be an AW type.
 

PEUGEOT CONFIRMED number is 1635056080 for AXN8 speed needs new AW2 fluid:​

Super Low Viscosity ATF; AW-2 2018-01-1756​

Reducing loss torque in automatic transmissions (ATs) is a key factor in improving fuel economy. A promising approach is to reduce the viscosity of the Automatic Transmission Fluid (ATF) so as to minimize churning loss. Aisin AW and JXTG Nippon Oil & Energy Corporation have developed a super low viscosity ATF, called “AW-2”, which has approximately 50% lower kinematic viscosity at 40 °C compared to the conventional ATF “AW-1”. It is generally understood that if the viscosity of an ATF is too low, it can have a negative impact on the fatigue life of components such as gears and bearings, and possibly lead to increased wear or seizure. AW-2 was designed to solve these problems via the application of two key technologies. The first is a high performance base oil with a low traction coefficient, which translates to low viscosity under high pressure conditions. This decreases the shear resistance between sliding surfaces under elastohydrodynamic lubrication (EHL) conditions, which contributes in improving the fatigue life of bearings and other components. The second is an ester type base oil with high polarity. It was found that the amount of ester base oil used has a major influence on fatigue life. The adsorption of esters onto metal surfaces is thought to improve lubricity in severe lubrication conditions. Durability tests were performed in a wide range of conditions, using gear and bearing components and actual transmission units, and it was confirmed that AW-2 outperforms AW-1, despite its super low viscosity. Furthermore, AW-2 reduced loss torque in the transmission by approximately 10%.
 
I really hope that on the long run, this doesn't prove to be a failure like PSA' low SAPS engine oils.

The price of transmission fluid that complies with AW2 for peugeot 2020 eat 8 speed with part number 163505608 is $304 australian dollars for 2 LITRES only.
Who is going to service this at $1200 for a trans flush? OR are we expected to throw it away after only a few years when it's damaged?
