Complete transmission cooler kit for Prado 150 Diesel with Automatic Transmission
2mm thick Stainless steel cooler brackets with G8.8 bolts.  Bolts to existing holes and does not require drilling or screwing into vehicle.

Davies Craig 678 Cooler kit.  Comes with hose clamps and oil cooler hose.

1.5m of 3/8" oil cooler hose.  Extra hose that is required to install.
Allow about 1-2 hours for installation.  

You will also require 300mL of AT fluid to fill the cooler and lines.


Q:  Should I install the cooler before or after the factory cooler?

A:  The short answer is that before or after the radiator will work.

The return line is the bottom hose.  This was confirmed after the videos were made and there is a note in the video description correcting this.

Using the bottom line will place the cooler after the radiator as per Davies Craig recommendation.

Both the Prado and FJ are connected to the top line and performance of the coolers have been consistent with expectations.  Ie 20-30 reduction in ATF temp.

Barbs down may cause an air lock and not allow the cooler to fill completely reducing efficiency.  However Wholesale Automatics who are a reputable and trusted auto transmission specialist have their kits with barbs down.  I assume that they must feel it is not too much of an issue.

Maybe a easier install

I will be getting your kit for my 150 , I did have a cooler on my 120 and I didn’t go all the way to the gearbox with my hose but just put a double tail on the top hose and put the hose on that, less mess I thought less possibly contamination

Awesome Kit...

Great kit and seeing temps way lower than before... Upto 30c lower.... Impressive... A few tips.. The hose supplied is 3/8 which is 9.5mm, so slipping them on the metal return nipple is difficult. Use a bit of grease on any of the fittings to make the hose slide all the way on easily. Also fit the bracket exactly as the video says. The front grill should also be removed to make is easier. With the front grill removed you can do all the plates and cooler up loose and get it perfect. Also the genuine hose clamps are easier that the supplied hose clamps!

Fast delivery, well packaged. The kit and all the bits were machined for a perfect fit, everything aligned and all the gear to do the job was there. Good product and Aussie made.
