    Roughly but if you dump all the fluid in before starting engine it will be running out the vent...

    as Krazy said, you will overfill it without the engine running. I would suggest putting 1 qt. of fluid in the converter before installing it. add 4 qts, start the engine and check the level. add another qt. if nothing on the stick. once getting reading on stick, add a little at a time until full. make your last check with engine at operating temp. also be sure to use the correct transmission fluid.

    I sure wish this internet stuff was around when I was about 22. Would have saved me some stress and extra cash. lol

    And I concur 100% on the type F being used on stock clutches as well. Has something to do with the friction modifiers or base package or something like that.

    I just assumed that the Trans was drained.. not actually rebuilt. If it's been running any particular fluid up to this point.. what's so important about moving away from type f? Have you had issues with it in the past?

    If it has aftermarket clutches I'd run a good quality synthetic with a good friction modifier package. Have had great experiences with royal purple, amsoil, even b&m trick shift ain't so bad if you're looking to up the line pressure a tad more too.

    You'll get firmer shifts with F fluid, GM guys used to use it in their Turbo 350 & 400 trans instead of Dextron... For nine years I ran nothing but F in the Bird AOD, has around 750 drag strip passes still shifts fine(may wind up in Comet)... Also I put 98K miles on a slipping AODE before it finally puked due to blowing a front pump to case gasket... It had line pressure increased to help with shifts, that eventually blew the gasket...

    My C4 is fresh, has F and is the way it gonna be...

    Sounds pretty familiar and I don't doubt it one bit. The only fluid that I have seen which will raise line pressure beyond conventional type F is B&M's trickshift fluid. Not much else I'd buy from that company any more these days but that stuff works surprisingly well in most hot street setups I've driven and felt riding along in the passenger seat.

    I called to talk to guy who has been working on ford trannys for yrs,I tol dhim my situation and he said use type-f so I guess its what im going with for this c-4
    the thing is I don't know what fluid it had in it ,that I drained out that is,all I know if this tranny had been built at one time a few yrs back just not a lot o fmiles ,jst sat up for a while until I pulled the maverick apart to change engines,it may have had type-f more than likely
