Things needed :
My cooler was taken from a Volvo. Not too small, not too big. I have to saw off the metal lines and just use a little bit of the line protruding out to connect to the hoses. Make sure you clean the cooler and ensure the oil lines are not blocked. In my case one of the lines had so much rubbish it was almost clogged. Use a little degreaser and force feed the oil line with a strong water hose to clear it out.
When you sawed off the line of the original and left abit of the line protruding out to connect the hose did you flare the original pipe. If not I suggest you do as the pressure and vibration plus the slipperiness of the ATF might pop the pipe off. Use a flaring tool, if the pipe is too hard bring to machine shop to get it flared so the hose clip and the hose wont pop off.
Good DIY job by the way. I also have a similar set up on my nissan cefiro and has worked well for 14 yrs. Still using the original trans with no problems and the trans has done about 280,000km+++ with 50k oil change interval.
The Pajero cooling coil? What cooling coil? You can use the gearbox cooler from Pajero. In fact mine is a Pajero cooler. Ok what.
cooling coil ???
u meant the oil cooler is it ?
as long small one can already ... wunt drop too much pressure...
should be gearbox cooler. wont too cool ah?
not sure also. got so many cooler?
i dunno which is which.
Do u bypass the raditor?

kalau nk pasang oil engine cooler kena ad adaptor ker?
or same like atf cooler just hose only
It is a very good DIY especially for malaysian weather however my worries are only on oil line and oil cooler,it needs constant care on oil lines and cooler especially on leakage and pressure,as I know the pressure on the lines are more compared while on the gearbox itself so when there is slight leakage it burst out like open wound on the other hand if it is just the gearbox even any oil spill will not effect much as it drips slightly in longer period of time depends on the gasket.Whats ur opinion on this guys?
You should bypass the radiator because the radiator will have less heat load from the trans when its hot and vice versa the radiator will not heat the trans oil up as the radiator temp is usually about 85-90degs. Only problem with bypassing the radiator is that some trans needs to warmup to have smoother shifts without the radiator heating up the trans fluid it will take longer for the trans to warm up. If you decide to not bypass the radiator, install the external cooler after the radiator.
In the case of my Myvi and Wira though, it doesn't need warming up so it works great for me either way. For more advanced cars like the Golf and all, they work differently and usually for cars at that price range, they come with ATF coolers anyway.
The ATF cooler in my cefiro with the radiator bypassed, when its cold the shifts not so smooth.
Arlow kawan, your car is a more sophisticated, more expensive and way bigger car than my 3-speed Wira and humble Myvi!
What sort of oil does it use? Is it a normal 5-speed torque converter gearbox type?
12savefuel gave some good advice: the auto trans makes a LOT of pressure. Be sure you use good hose with flared lines. Regular fuel hose is NOT what you want... you need something with a better rating and doesnt break down.
ATF can burn and if you have a leak under pressure you risk killing the trans. All for a cooler very few cars actually need.

Do I Need An Auxiliary Automatic Transmission Cooler?
Engine oil coolers are the same as ATF oil coolers. The only difference is how they are connected to the car. Engine oil coolers need the oil filter adaptor and people usually use steel braided hoses. For ATF it's fine to just use rubber hoses and no need for adaptors.

Errrmmm, you need to be careful. Engine oil coolers are not normally the same as transmission oil coolers. At least they shouldn't be. Engine oil pumps are gear type pumps which are what they call positive displacement (i.e. high pressure). Transmission is a centrifugal pump (lower pressure). You would normally see engine oil coolers being the fin-tube of frame type, not like the radiator style of the transmission oil cooler.
