'86 430 Auto trans cooler ?

Hi all, I just found this ad (no idea if it's current or old)

http://www.kijiji.ca/v-dirt-bikes-m...ing/589083124?enableSearchNavigationFlag=true

and one of the pics of it show some kind of cooler.....is this for the water cooling or is it a gearbox cooling system - does anyone know?

would be cool to see if something like this could be modded for the 500AE.....

I don't see an oil cooler. The black shroud is for water.
On another thread, was presented an device for oil cooling
built from an 110 ATC oilpump.

ok so the hoses into the side of the gearbox are for water.....ok
it just looked so close to the oil filler cap that I thought it was for the fluid.

These pics were sended by Kartwheel.
The 110 ATC oilpump added to the cover.

I see the oil pump in front of the sprocket, what is the big round thing? im guessing its electric. not gear driven?
the oil cooler is xr250?

Oil filter !

Ah ok!, then the pump is driving off the 2/3rd gear shaft?? Nice work.
