T5 and Mercon V?

S-Car-Go · Sep 16, 2007

For the life of me I can't remember what kind of ATF to use in a T5. I bought some Mercon V, but now I'm not sure. What's the "approved" fluid?
Thanks.

Dextron III/Mercon is the standard stuff to run in a T-5. The manufacturer also recommends Mobil 1 synthetic ATF if the car will only be operated at 30* F and above.

That splains why I couln't find Dextron III/Mercon at Autozone. Choices were Mercon V or Dextron VI only. I picked up the Merc V because it said it was for Fords.

Closer examination says its for all Ford Mercon applications except Mercon SP or type F fluids.

use mobile 1 synthetic dextron atf and buy a shifter with built in stops to protect a t5 properly. imho.
