This is a simple DIY - and there's a fair bit of info out there but I thought I'd put what I've found together in one article.

This is the preferred connection of the trans cooler - ie before the radiator and with a bypass thermostat.

For my S-edition there's no external ATF filter so no problem with where to locate the thermostat.

This is the thermostat I bought.

And I bought a Davies Craig Cooler from SCA.

Firstly I mounted the cooler - just a couple of custom brackets required.

Next spent some time tracing the ATF lines out and back. My lines were like this: -

So then it was just a case of adding the thermostat and plumbing everything in. I found the thermostat fitted ok as shown below:-

This location allows the ATF pipes to run nicely but won't allow you to put the plastic undertray back on. I never liked it anyway. ;)

I held it in place with a cable tie then modified an L - bracket to fix it properly.
Here's how it finished up with the bumper back on.

I had a spare 1litre bottle of trans fluid at the ready for spillage and working out which was the return line. The whole 1litre went in.
Quick check for leaks on the driveway - all good - now to take her for a spin.

Hope this DIY is useful.

Nice work there smelmechiz :thumbs:
You can also take the car for a short drive, then on return have a feel of the hoses to see which one is cooler and that's your return line :ok:

Fair enough, I was a little skeptical at first about this technique, so I ended up feeling the hoses after a longer drive and noticed a difference

Confirmation that this is the correct orientation. See page 5.

Is there not any kind of thermostat in the trans already?

Not as far as I know. Basically the ATF just circulates through the transmission and heat exchanger at the bottom of the radiator and gradually heats up.
The new thermostat is supposed to stabilise temperatures of the ATF - blocking off the cooler when temps are cool, and opening up when things get hot.

I've got to get a temp. gauge so I can keep tabs on whats going on.

Anyone know if the PLX connection gets the ATF temperature direct - or am I going to need to plumb in a temp sensor?

Got the manufacturers custom bracket delivered during the week and fixed the thermostat properly.

It's now solid as.

Another way to test which is the return line is to pull one of the hoses off (add a small section of hose the now exposed hard line, and have a bucket below both hoses) then start the car and see which hose the fluid comes out of.

Did you do a flush while at it?
