727 Fluid Type

Good ole Dexron 3 works just fine. Type F (Ford stuff) was recommended for yrs. by B&M in their shift kits. I forget their reasoning but supposedly they thought it was better. It does provide a ever so slightly more solid shift but there's also disadvantages I've read. Sorry, it's been so long since I read about the properties I don't remember what the +'s and -'s were so for that reason i just use what Mopar recommends which is Dexron 3.
