dexron/mercon 5 in mine.

I've seen the fluid issue debated many times. Many testimonials for mercon derivatives, and type F fluids.


Personally, I think that over all these years of torqueflight use, by many different party's, one thing has been proven.... That A 727 doesn't care what fluid you use AS LONG as it was built right

Cheapo (beacause it leaks ) type F as well.

autozone/advance auto type F. been running it since rebuilt in 2003 and still going strong.

727 6 clutches, billet steel drum, dex3 as per trans builders suggestion. sometimes doing the rounds the trans gets hot but you'd never guess with smelling my fluid. i did try type F but trans man said no so dex 3 it is.

Duraguard universal hydraulic fluid !!!!!
its thicker werks grate for high HP.

tranny been bulit proof for 4 years till now the T brake solenoid quit.

Yup but it also makes converter slip less!!!

Type F since 1973 when we ran a Art Carr trans,Marv ripes at A-1 trans says type F in 727, Dave Smitth at Pro Trans says type F with no trans brake. Mopar engineers in the old drag racing seminars said type F also

Nothing but cheapo type-F
