Coolant for gear box?

[littlebeetle]

Is this necessary to be install to cool down the gearbox especially travelling long haul.
I came to heard that this could help to prevent the gearbox from overheat.

Would like to seek for some advice.

Thanks.

u mean oil cooler? its better to have one since it keeps the temp down, good way to prolong your engine life..
what car btw?

Yup. A transmission cooler.

Mine is a Saab 93 turbo.

I understand my car has a small one...so am thinking should I still get a big on install.

if u already have one, i guess its enough.. unless u stress out the transmission like travelling with a heavy load and/or constant high speed..
one of the reason to have a tranny oil cooler is to avoid the ATF to get too hot and cause problems later but its ok since u already have one..

install a fan infront of the oil cooler....

 

[JINEIL2EN]

oso can install behind the oil cooler...

NO . For better performance , INSTALL Large Cooler for Transmission. Or else transmission too hot and Burn the Clutch plate inside

What size cooler ? i got few suggestion ..

1. ALUMINIUM Radiator Size . DAMN Cool for Auto tranny .
ps : Dont Share with engine radiator . You install NEW set of alu radiator for gearbox ..

2. Install a Cooling Coil On / Side of cooler .
use back Stock car Air Cond Cooling Coil . so that cooler will Cold like Ice ~~

Guarantee ur tranny will hav BESt Pickup .. Topspeed ..and Matspeed .. GUARANTEED ..

Dun go oversize wif ur cooler. Coz it will cause pressure to drop.

i fix 2 cooler in front of radiator...does this mean i have to install 2 fan in front? or just use the cussent 2 fan behind radiator?

cause after driving a while, when touch the cooler,walauwei damn hot takut too hot only...

 

[SkYwAlKeR]

No need fix fan laa. This is not radiator. When the car moves, rushing air will cool it down.

unless ur car racing in endurance...

 

[DanzEterna]

can the ATF cooler used for MTF cooler as well?

 

[JINEIL2EN]

oil cooler is far hotter compare to radiator... dont fix them too close together or else heat from ur oil cooler will be transfered to ur radiator... same reason why people dont fix radiator and intercooler so close together...

if u worry, go PC shop buy 4.5" casing fan fix on it lo...

can the ATF cooler used for MTF cooler as well?

no need laa... buy boron nitrate kasi spray ur whole gearbox with it can liao.... it can help dissipate heat miaa...

dont use computer fan for cai... coz at mid-high rpm, the amount of air flowing into ur intake is alot more compare to the airflow of ur computer fan... in the end, u will get a restrictive air flow at high rpm due to the fan blocking the intake path...

as for ATF cooler installing fan is different story... coz u are installing the fan at the back of ur cooler... when ur car is stationary, there is no airflow to the cooler... hence u have a fan sucking air through the cooler, cooling it down... when ur car starts to move, rushing air will take over the job, eliminating the use of ur PC fan...

just fix the pc fan behind the cooler.. total of 4 fans..but then now i have over heating problem.

i fix back the direct fan to normal that means to follow the fan switch..
but when start car, when heat up the fan didn't switch on...checked all the fius and possible wiring couldn't find.. if the fan late to switch on what could cause the problem?

termostat can control fan?
or the fan switch need to change?which i change before..

 

[DanzEterna]

sure ah can fit PC fan...? i got lots of it.....
how bout the wiring? if kena water wont rosak meh?
