75 smackaroos to do a fluid exchange? ><

Only need 2. Tranny takes 2.1 dry. Mine sat for a week with the plug out and 2 was still more than enough.

When I did the cluch last year I replaced my fluid with the Ford fluid.

The trans used to have a problem popping out of 2nd gear. That problem is gone.

Also, now, once the trans is warm, shifting from gear to gear is smooth as silk. On my other Focus with the MTX it's still running the original factory fill (most likely) and shifting is a lot rougher.

$25 a quart is indeed highway robbery but the reason it's so expensive is that the additive pack is patented. As you undoubtedly know Ford does not make fluid they get a oil company to make it to their specs. The Ford MTX transmission fluid is nothing more than synthetic gear oil plus that additive package, the additive package is where all the magic is.

What Ford did here is the same thing that Chrysler did with their ATF +4. Ford went to the oil company and said "you develop a fluid for free for our specs and sell it to us for $100 a barrel for our assembly lines - and in exchange we will give you an exclusive outlet for the next 15 years for you to package and sell quarts of the stuff for whatever the heck price you want to the general public"

The oil company is free to sell their patented additive package to any fluid maker who wants to sell synthetic transmission fluid for the MTX and they do. Of course, they probably charge $24 an ounce, with 1 ounced needed to treat a quart of gear oil, which is why nobody buys it and sells a competing product.

And since people have no other source to go to than the dealer, the oil company charges whatever the heck it feels like, and the dealership tacks a fat markup on that.

Don't you love a monopoly?

Well it's good to know that two will fill her up.
And if it is a "lifetime" fluid then fifty isn't too much too ask for the piece of mind of having put the right Ford stuff in it.

It isn't lifetime, it's 100,000 miles. But make sure that you call around if there is more than one dealer near you. I had a price difference of $5 a quart (26 vs. 21) between the three dealers withing 8 miles of me.

if you can do the work yourself (it's not that hard) then $50 really isn't that much. a shop would charge five times that much to do it for you. and as said above; it's well worth the cost to get the right fluid now rather than have it break on you later and need a lot more money to fix it.

[PRSman25]

Oh yeah I'm definitely doing it myself. It's too simple not to.

I use Mobile Syn 50wt oil in all the MTX-75 I do

[PRSman25]

That's basically diesel oil correct? Or is there a 50w gear oil?

Edit: I found the fluid. Delvac 50 weight manual transmission fluid.
Now, where do you get it?

The Ford honey is made in Germany FWIW

I've been looking around and have found that 75w-90 would work.
But what is "safe" for the transmission?

Regular 75W-90 gear lube is not recommended for this transmission and will destroy it.
