C6 fluid type

Got 78 bronco with a 400 and c6. I'm wanting to do a filter and fluid change. I've read to use type f fluid. Is this correct?

"On May 1, 1976 the C6 transmission had a major modification to reduce driveline clunk."

"The C6 anti-clunk design uses CJ type fluid instead of type F."

Type CJ was later superseded by Dexron/Mercon and type CJ disappeared. So any C6 trans built since May 1, 1976 should use Dexron/Mercon.

Run Wolf's Head super universal synthetic. It's supposed to cover both Mercon/Dexron and Type F specs.
