I may know a fix for some of the DCT issues. Hear me out.....

Let me leave a little input here.

Not sure on the MK3 focus, but my mazda6 has the transmission cooler built into the radiator. The cooler is too small and has low coolant flow for what the trans needs. It's common on all atx mazda 6s.

It will cause hard shifting, jerking during parking, and wineing when extremely hot. In 90 degree weather no matter what, you have to deal with it all day long or short drives.

Over time if nothing is done, it will cause early transmission failure. Which will force trans rebuilding or replacement.

There is a cheap fix well known in mazda community, and it maybe the answer to your DCT problems.

You will also need to get some hose to make the connections.

And here is a how-to for doing it on the mazda6.

http://www.xsadclan.com/files/6/Mazd..._cooler_6s.pdf





The kit comes with almost everything you need for the install. It comes with one hose but you will need two. Which you can order 11/32 x 4.5 hose at your local auto parts store for under 15 bucks. Much cheaper than to replace a transmission.


Here is what the kit includes.

This is not an option for DCT equipped cars.They do not have a conventional automatic with tranny lines that can be plumbed into.

The DCT is a sealed unit and doesen't rely on volumes of tranny fluid to keep it cool.

Taking off the under engine shield may help somewhat but it still won't cure a bad design.

I would have to agree, with the Mazda 6's the fluid sounds like its getting too hot, but with the DCT, even if it is getting above its optimal temp there isn't realy a way to cool the fluid even if that was the issue, it would be like trying to put a tranny cooler on a manual transmission car.

My Contour SVT with the SAME MTX-75 tranny had a transmission cooler with lines to a small radiator behind the main one.
So the MTX 75 may have the ability to have a cooler added.
I do not know if ALL of the MTX-75 have the ability to add on a cooler or not.
Just wanted to mention that SOME MTX-75 did have an external cooler OEM from Ford.

So, there was some sort of pump added to the MTX-75 on the Contour SVT, to pump gear oil through an air/oil heat exchanger (radiator)? hmmm....

There was an oil/water exchanger that was used on the Contour SVT for engine oil cooling. I think you might be confusing that with a transmission cooler.

From what I've read on the mazda forums the mtx trans they run on the V6 also has cooler. It also can over heat and can use the after market cooler. It wasn't till '06 when they came out with the 6 speed transmission did the problems go away.

If that's true, then there has to be a special pump on the mtx/V6 Mazdas to pump the trans oil through the cooler. How would you propose to pump the gear oil from the DCT through the cooler kit in your opening post? The cooler you posted is designed for ATF, which has much less viscosity than the 75W lubricant in the DCT.

Even though it doesn't apply, I'm glad to see people throwing out ideas. I still need to try dan50's intake idea.
