Does a 6-speed automatic transmission w/OD lock-up torque converter require Transmission fluid? The vehicle is a 2012 Hyundai Accent.

  • An automatic transmission does need fluid. Not sure what you mean by a sealed unit? – cano Jul 1 '17 at 2:52
  • Even in BMW 5 series I've seen sealed AT systems. – Numair Aidroos Jul 1 '17 at 23:02
  • "An automatic transmission does need fluid" they have since they were invented. – Moab Jul 2 '17 at 1:26

The CVT transmission available as an option on the Hyundai Accent is (supposedly) sealed for life. The 6-speed automatic transmission is not sealed for life, and is inspected on a 'service 3' schedule (24,000, 72,000, 120,000, 168,000 miles, etc). There is no schedule for replacing the fluid, unless one of those inspections finds an issue.

If you have a problem with the transmission on that particular vehicle, be aware that the power train is covered by a 10year/100,000 miles warranty - so let the dealer sort any issues out rather than doing it yourself.
