Moving Factory Trans Cooler

[KiwiRS4T]

I understand the need for the heat exchanger but the coolant in the radiator won't flow until the thermostat opens regardless of the size of the radiator. Here in QLD it can get to zero in winter and rise to over forty in summer. In winter I can see the need for the heat exchanger in the radiator so the plan after new year is to go to the local wreckers and pick up an old copper radiator with the auto line in it and cut it open to see what it looks like (straight pipe or fined). If it is a straight pipe I will buy an aluminum radiator and have it modified then I should have the best of both worlds (unless someone knows where I can get one ready maid)

After paying ($2,800) to have my auto overhauled I want to treat it right.

Cheers

Regardless of how cold it is the water will still heat up before the atf. In NZ I am able to buy a generic thicker radiator core with the auto connections and which fits the Stagea through Natrad. I would think they would be available in Aus and would be half the price of getting one custom made. Maybe just ask your local radiator shop to check out the availability of a suitable thicker replacement?

I have rung Natrad here in QLD Toowoomba and they told me that they did not have a listing for the stagea. If you have part # I will give them another go.

Its not a Stagea radiator - they just have a catalogue and find a picture of a radiator the right size and with the pipes in the right place. I'll go down to my local on Tuesday and see if I can get a reference.

The way your trans cooler was mounted with the hose fittings at the bottom will trap the air at the top of the cooler and not allow the oil to pass through all of the cooler fins. This is why the standard cooler is mounted with one fitting at the top and one at the bottom. It allows the air to bleed out of the cooler.

I would suggest putting the hose fittings at the top.

This is true; I assume they pressure-bled the system or something. Unfortunately it's no small feat to turn the cooler upside-down; I'll ask the transmission place about it next time I see them, thanks.
