I've always defaulted to the manufacturer specified schedule of
maintenance for my card (2013 Elantra GLS, 49k miles). I was at the
dealer today to get an oil change and do two recall fixes and they said
I should have gotten my tranny fluid replaced at 30k as well as a
coolant flush at 30k miles.
Manufacturer schedule (https://www.hyundaiusa.com/maintenance-schedule /)
says nothing about tranny fluid replacement even up to 150k miles.
Coolant, however, it says to change at 120k miles. Since I am an
informed consumer and I know today's coolant and tranny fluids can go an
obscene amount of miles before needing a change, are they just looking
for cash? I should expect to change coolant before 120k miles though, no?
