AMG GTS 2018 Trans fluid confussion?
As the title says, I'm a bit confused about which transmission fluid I need for my 2018 AMG GTS.
From what I've found, Shell Spirax S5 seems to be the recommended fluid. However, the bottle lists Mercedes approval MB 236.26, while the Mercedes documentation appear to specify MB 236.25 for my transmission.
Can anyone clarify the difference between 236.25 and 236.26, and whether Shell Spirax S5 is actually the correct fluid for this application?
I'd really appreciate any advice from someone familiar with these transmissions, as I need to do a transmission fluid service/flush ASAP and want to make sure I'm using the correct fluid.
EDIT: NOT DOING THIS SERVICE MYSELF

If you plan to DIY the service, make sure you do not confuse which fluid goes where. The procedure must be followed exactly.
