Re: Protrans Fluid
 

my understanding is Type A is for older automatics ( like in the 60's) --Type F is for stuff up to the late 70's---Dexron/Mercon for up to the late 80's early 90's---FA replaces both A & F--- dexron II & III is the replacement for all of the previous fluids---F has the best friction modifiers for the harshest/firmer shifts in a racing trans------Best advice "follow the trans builders reccomendations"---Comp387

Not sure about stockers or S/Stockers. But I know a few bracket guys who use straight hydraulic oil from tractor supply.Buy it in 5 gal pails much cheaper than ATF and they swear by it.----I dont know never tried it.

I have a couple of pro-flites. I was told by both Dave and marv to run type F.
