Transmission flush vs drain and fill [Peugeot 508 GT 2019 EAT8]
56 000 miles / 90 000km.
Peugeot says this torque converter gearbox is sealed for life, but I still want to service it.
Car is now 7 years old. I see many different opinions with pros and cons on flush vs drain and fill. Money is not a thing I am considering here, if the more expensive option is genuinely better, I will go for it.
Which one to actually pick? Goal is reduce risk but also actually prolong gearbox lifetime. As per today the gearbox functions completely OK. Any gearbox / Peugeot specialists here that may know what's better?
