Re: WK2 145k Service
https://www.transmissiondigest.com/8l90-the-other-8-speed-automatic-general-motors-very-own-production-transmission/ When GM developed the 6L80/6L90 transmission series, they were loosely based upon the ZF 6HP family of transmissions. The 8L90 also has a ZF thumbprint on it, though somewhat less tha...

Re: WK2 145k Service
https://en.wikipedia.org/wiki/ZF_8HP_transmission Related GM 8L transmission Hmm. I tried looking into this a year ago and never got to the bottom of it. https://en.wikipedia.org/wiki/GM_8L_transmission Both gearboxes are based on the layout of the ZF 8HP transmission from 2008, with the only differ...

Re: 2017 GLS550 135k Service
Side note (new post): this transmission is way older than I realized. Well, "way" is a relative term. https://en.wikipedia.org/wiki/Mercedes-Benz_9G-Tronic_transmission But this claims 2013 production and then initially being offered in the 2014 E350 Bluetec (diesel). It's not clear if thi...

Re: 2017 GLS550 135k Service
I really wish there was a way to know which fluid will help the Benz transmission live the longest, whether there is a viscosity difference or not. Agreed - but all we can really do from here is compare specs and make an engineering assessment. Anecdotally (I haven't done any research), I believe D...

Re: 2017 GLS550 135k Service
I did see the possibility on FCP Euro that you can use the 236.17 (gold/yellow) in 236.15 applications which tells me they are equally thin. https://www.fcpeuro.com/blog/mercedes-benz-722.9-transmission-service-modifications On the 7G-TRONIC PLUS transmissions, we recommend running the latest versi...

Re: 2017 GLS550 135k Service
236.15: A89 update for the FE spec, thinner fluid. They didn't just change the fluid - they changed the pans, filters, possibly frictions (looking for proof though), and added the A89 coding to the datacard. We can see how much thinner it is. This would cover all 7-speed applications from 2010 or 2...

Re: 2017 GLS550 135k Service
That viscosity is WAY thinner for the FE fluid, and Maxlife magically claims they can handle both applications with a single fluid. I believe 236.17 has a similar viscosity to the 236.15 update. However, Mercedes (and the aftermarket fluids that target these specs) say you CANNOT interchange 236.14...

That's actually a local user setting. It is in the user control panel. This link MIGHT work for you: ucp.php?sid=b8c54c04de488d13fb67c5cbf0a1a2f1&i=372

Re: WK2 145k Service
I haven't racked Valvoline MaxLife vs. 236.17 yet, but at least in the Lifeguard 8 comparison I think my conclusion would've been that the viscosities are functionally equivalent. Perhaps except at -40 degC, but I don't know how much that's relevant. I compared 236.14 and 236.15. They have VERY dif...
