CVT transmission oil cooler

The best way to eliminate or minimize "SLOW DOWN" warning (gearbox overheat) appear is by adding aftermarket ATF coolers. Currently there are many types of ATF coolers, lets disscuss it here. I'm on Hayden 677 Rapid Cool. So far no "slow down" since i install this, or maybe i havent whack my car maximum at high rev/speed.

Bro Elan,

Some Qs:

What's da damage?
Where was it installed ie at Quicksave & in front of radiator?
How long to install?
How much additional CVT oil?
Are you using both coolers or just 677 only?
Was the a measurement on temperature taken during normal drive b4 & after installing 677?
What's the temperature during idling b4 & after install?
What was the fastest you drove with this new Hayden 677 & for how long were you able to drive at that speed?


Sorry so much questions, i guess if its positive outcome, then it'll help to potential buyers to justify the change/purchase/upgrade.

Cheers!

RM280
Installation around 1 hour DIYed, bought it in KL through mudah.my
No additional cvt fluid required as it is within the medium level after installation.
Using only the 677 rapid cool paced in front of radiator for direct air.
No temperature measurement taken.
Drove 210-220 around 80 second, before and after that 180-200 for few minutes.

good product. my hyden rapidcool smaller than this.. hihh

try not to use hayden tube and fin type, it is not efficient as rapidcool.

I am using Hayden Dawg. It comes with a fan. I installed in QS. Damage = RM 880 inclusive labour + 1 litre of Mitsu CVT oil (top up).

It receives CVT oil from GB, exit to the stock CVT cooler and back to GB. In other words i get 2 times cooling before sending the oil back to GB. I had the fan tapped to aircond.

Someone commented that this set up may cause low CVT pressure and the outcome may be worse before installing. I was advised to remove stock CVT cooler to avoid low pressure.

Haven't had a chance to whack the car hard. Will try out these few days

yes bro, too long passage for the cvt fluid to travel may cause low pressure (cause the pump is small), and it may shorten the life of the cvt fluid pump.

ayoyohh.. besarnya kipas.. mine was small hyden. also attached to stock cvt cooler.
i got 'slow down' sign when speed around 220 after i installed it.
but after replace new CVT cooler on my 80k service, so far no "slow down" even go for 6500rpm & 220 speed. but not too long

bro GG, 6500rpm?

aiyooo... 6250rpm lar... sikit2 pun mau kira ke? ha2
stil cannot hack the rpm cut.

thought can 6.5 liao..that's damn blardy good news woei..LOL

Afta install steel intake pipe, suddently slow down warning apear... Aiyo...

time for u to install cvt cooler bro..

Spray boron on CVT cooler.

but it wont help much, better add aftermarket cooler.

Then sell car and buy better car lo... hehehehe

Any idea what's the optimal CVT operating temperature?

Is there any way to monitor the oil temperature?

u can add temperature gauge to monitor it.

make sure additional cvt cooler hose properly fix.. otherwise leaking like me.. wrghhkk

Bros,
I have seen all Mutiara evo x fixed with this ATF ..M7 brand...plan to install it too..

Bro... No more mod lar for ur 4b11. Save the money for ur eagle.

Hi dear

I want to install aft oil cooler on Lancer EX ,, How can I install and can you show your picture ?

How can I connect to the gear box?

Thank

Hi.

Before you install a CVT oil cooler, you can buy some simple water pipes and tubes to funnel more air to the factory installed cooler. The funnel will channel air from the front grill (lower part) and straight to the cooler.
