What is the mileage done? atf not changed before?

dextron III for myvi, mineral and synthetic based.

just use synthetic based...it wont cost so much

Is it? I thought usually synthetic will cost much more.
But if doing oil pan atf change, isn't it better to use back the same brand and type as you are just mixing the atf up, unless you are doing a flush?

Guys, My ATF tends to overheat. if I install a ATF cooler, can i install the same oil and pressure sensor, just like those oil coolers? or need to modify the fittings? Hope Sifu here can enlighten me.

Any good durable ATF would recommend? Driving a old waja

perhaps can try out lubegard platinum before installing additional coolers, if it resolves your problem, thats the end of it. if it doesnt, you just waste ~rm100, not too expensive compared to going through permanent hardware changes/mods which usually cost more, and may not resolve your issue.

Yes can, but need workshop that really know what they are doing with those fitting. If money not a option then go for steel tubing -custom made line from the tran to the radiator to the atf cooler and back to tran. Install a fan too. For the ATF fluid, i think it better to use back the ori ATF fluid because the tran already old. Changing new one might lead to abnormal gearbox issue. (in some cases only)

just add one additional cooler...few hundreds.

and when u meant overheat.....how u know its overheat?

^

exactly.

Hunch?. Cause during cold start etc it's ok. After spirited drive etc, there's a delay when I shift from N to D. Delay is like close to 2 second before the car engages gear. Some of my friends told me it's the transmission overheat or most likely insufficient ATF fluid. When I let the car cool down the next day it's ok till I drive the car hard.

Yes. I heard need to pull out the transmission cover and fabricate a port. Definitely use steel braided hose since it's high pressure. As I'm well aware the transmission peak working temp is less than 110 degrees. anything above, will result in ATF fluid being burn off. Thus, I was hoping if anyone did attempt to install sensors to tap the temperature. It would be great to know we're not stressing the transmission too much

Yes. Also thinking an option to install fan. But, standard fans are too big to be fitted on the cooler. May need to go with passive cooling since there isn't much space in under the hood. Hence I need to know the temperature.

just remove d atf cooling hose from radiator to external cooler. done... dun need so complicated

some ppl do in this way (either one)

atf -> radiator -> external cooler -> back to AT

atf -> external cooler -> radiator -> back to AT

atf -> external cooler -> back to AT

which one is better is depends on individual

No harm as an external cooler is always better.
Try checking if Penzzoil Multi Vehicle ATF is compatible with your current atf. A few of my Honda friends have switched over because the Honda atf prices have sky rocketed. Penzzoil Multi Vehicle ATF is FS atf, and is quite cheap.

Added on December 28, 2011, 3:34 pmLooks like sign of overheating, but do you need steel braided hose? Your normal hoses are rubber ones, right?
Even my engine oil cooler hoses are the rubber type, and they are running hotter then the atf.....

Thanks guys. Just got my ATF cooler. It's not cooling the ATF as I thought. It's to cool the return radiator water to auto gearbox as brother Kenny mentioned. They told me to install.

atf -> radiator -> external cooler -> back to AT

Want to try

atf -> external cooler -> back to AT

But not sure if the auto transmission got pump to drive the radiator. Brother Kenny. Can help to confirm?

in our hot country better to bypass radiator completely, in cold country it serves double purpose to also warm the ATF.
Besides to me it's stupid to still use the radiator one because lets say traffic jam and the water is 80-90 degrees but the AT is only 60 degrees, it'll start heating the oil instead or the external cooler is cooling the radiator.

Plus the longer the lines the higher chance of leakage and i don't like the fact there is chance if there is a leak in the radiator one, water can get into the GB and ruin it.

Did you try to find out the cause of overheating or not first?

I whack my car too hard. Huhu.

If run external standalone cooler, I think need to make sure the placement is correct else it will suck in hot air. The radiator is tad small. Seller recommends me to install fan.

Was about to say you have spirited drive......

Many cars actually don't have an atf cooler, so I think fitting one will be good.
The only thing is the place to install it. If can face the front, I don't think you need the fan....

just make simple bracket and mount in front of radiator, no need fan, fan at high speed become a restriction as long ambient is cooler than the gb cooling willl take place

thats why la, i whack my car hard also, time to time maintain red line 6-7k rpm, also no problem shifting etc.

thats why i recommended lubegard, maybe it works for him, maybe not, however its not something permanent, and the cost isnt exactly a few hundred or so to speak.

thanks folks, my car ar... *sigh* still along list of upgrades... Next might be oil coolers...

anyone here know how to install OCT on campro?? got two holes on top of the rocker cover. which to connect? the left one I put a small breather.

Yup, some mentioned using lubegard does help too......

hence the recommendation to try, i was also specific that it may or may not help
