    to those of you that think you can only put mercon/dexron III in these trannies.. know this.

    ford only specifies that fluid to make it easier to shift. mazda, whose tranny it really is, specifies 75-90 gear oil.

    the best is 5w30 snythetic motor oil. the mazda techs at work all told me this.

    and btw, there is a fill bolt on the side of the transmission.. its always been there.. above the reverse switch.

    you fill it there with a hose or whatever until the fluid reaches the hole and spills out a bit.

    I would like to post that one of the most important things involved with taking the VSS out in any condition is to make darn sure that nothing goes down the hole. If it doesn't mess up the gears it could end up in the little pocket with the mechanism that follows the 'H' pattern and mess up your shifting ( driving you nuts ). (see pic )

    I found that you can use the clamp bracket as a wrench and turn the VSS on the flats if it's not too froze. Maybe you could make more of a wrench to twist it instead of using vise-grips. ( VSS pic )

    I don't see any problem with using gear oil other than the ability of a heavier oil to flow well in the sheet metal drip tray that carries lube from the main case to the 5th gear end of the trans.
    You guys that run gear oil, any difference in the 5th gear operation?
    I'm still debating trying that one.

    This is good info, thanks!! I will probably mix some Merc V with a bottle of Redline MTL I have. If we're filling from the VSS hole (trans is NOT coming out of the car), is it confirmed then that 3.5 quarts is the correct fill amount?

    As far as VSS's go, I have to replace mine, as it's apparently leaking and ATF is dripping at my feet. I have looked at parts websites, and apparently it lists 2 different ones, one with 22, and one with 23 teeth. How do I know which one I need?

    Well, I'm going to Blow everyones minds. I've tried Gear oil, Dextron, everything. Eventually, they leaked out the shifter seals, and exploded. This is my 3rd transmission, and I was told, " this time try a nondetergant oil, use SAE-40!" So I did, and Wow, what an improvement. No leaks, No drips, No Errors! Make sure it's the Non-detergant Single weight! My grandpa, the tipster, has only ever used Single weight 40 oil in everything he has, motor and transmission. IDK if it's cause he used to get 5 gallons at a time for free or not, but hey! it worked!

    Has anybody had issues with the drain plugs leaking afterwards? I tightened it fairly tight, or so I thought. Do any of you replace that big copper crush washer? I wouldn't think you'd need to, but...

    When you are whacking the VSS with the Hammer are you under the car or coming down from the top. If you are under the car do you have rasied up? Jack stand? Lift?

    Which model year is yours?

    Hmmmm, like my old 1956, 1957, 1960 etc Fords? well, what year is yours? We had the tranny OUT and couldn't find a "side hole".......... so some might have it, but they sure forgot it on mine. Mine is 1993 LX SW 5spd of course. Had to do the "top hole" thing.

    Any other of you folks have a "side hole"?

    thx,

    reply to changing fluid the easy way!

    I love the original posters method!!! It saved me tons of trouble Thank you!!!
    Oh and I used a ton of teflon tape on the fitting to stop the leaking without putting it on too far.

    My belief is that the folks who have said they got the VSS out in 5 or 10 minutes didnt them really stuck in, like my cars were. I have taken the VSS out of 4 Escorts, all 2nd gen. LX's. In all four cases I did it with the transmission out of the car, sitting on a bench; which is the easy way if you are doing a clutch job or rebuilding the F4EAT. Only one of them came out by just taking off the clamp, rotating it with vise grips, and working it up.
    The other 3 all required soaking (for days) with penetrating oil, tapping on the side of the bottom lip, & vise grips didnt make them rotate (but did slightly crush the metal). I used a wood chisel, driven sideways between the case and the bottom 'lip' on the VSS to get it broken free of its 'corrosion bond' to the case. And in two of the three cases I had to briefly heat it with my cutting torch just before driving the chisel in. After that it rotated with vise grips and I could work it up and out.

    I have no idea how I would have been able to do this with the trans in the car. Maybe a better man could have done it.

    The most recent VSS I removed will be the first one I have replaced though; as it has some stiffness when I turn it, that doesnt make me feel assured its okay.

    Not stuck

    Oh, that's admitted; I've only done ONE in my whole life, and had read the difficulties here before even trying it, so when my son said, look, dad, it was out in no time, and he thought I was crazy for all the "warnings" I had given him. So ADMITTED, it wasn't stuck, ha. We weren't smart or talented, just lucky for ONCE IN MY LIFE.

    Long story, but they say the clutch was replaced recently before I bought it in Jan 2006, so when we had to REPLACE the clutch in Jan 2008, the VSS still had not had a chance to get RE-stuck.

    Originallly, I just thought they were a troublesome item to get out due to the nature of it, but I'm seeing they "grow" attached over a period of time.

    Yes, our tranny was out on the floor, making it easier as you say.

    Long story why the clutch was changed again in only two years. I drive like an old man because I AM an old man, and I need the car to "last". The story is elsewhere in here someplace.

    Short version; I agree with you; it was easy becasue it WASN'T STUCK. ha.

    i had filled my tranny in my egt i havent seen it in here unless i missed it but anyways when i did my clutch drained my tranny and so on got the tranny back in and lifted the passenger side of the vehicle pretty high so i coulod fill and and the fluid wont pour out and i filled it thru the drixeaxle hole and then slapped the axle back in and it worked i dont know if this was correct or not thats why i threw this post in i just figured if the fluid pours out when you pull an axle you should in turn be able to fill it from there correct?? but i do have a heavy grind going into second and a slight one into 4th but its only when im gettin after it, i know this is kinda off topic now but is this a sign my tranny is on its way out or could i use gear oil rather than whats recommened to too soften the clash of the gears also the slave and clutch master cyl is new and clutch is adjusted right sooo thats wont be a cause thanks for reading and hopefully some input would be greatly appreciated

    this was a great way of doing it, watching physics at work! I undid the drain plug and wacked at the vss for a while and after not getting anywhere with that and trying to find this other fill plug on the side I tried this method and it worked like a charm. Shes now full of Mobil 1 synthetic ATF

    No one else had my luck? Doing original posters idea and bought everything mentioned. A 1/2" hose barb won't even fit In drain plug hole, and def won't thread in. After figured this out I went and got a 3/8 hose barb made of a nylon I think (worse comes to worse can wad in there) and seems to work fine with crappy screw in but snugs up and all. Doing fluid fill tomorrow so see how that goes.

    91 gt 5speed btw. Don't know if I got a "freak" tranny or what

    Manual 1996 LX here, I got the VSS out with no problem, everyone says filling from the VSS hole is easier and that's what Chilton's/haynes says but I can only get a tablespoon in every 2 minutes through that hole, is this normal?
