hmmm...... that makes me think twice about putting the 3000 stally in behind mine... seems a waste now i got it, and also the car really does need a stally to get it up and going... but i need it to go on the highway too at legal speeds :| would a bigger tranny cooler allow it to slip more without overheating the box ??
insane should be fine mate
converters are designed to slip, as long as your tranny cooling is adequate, you wont have a problem, even on decent highway trips ....
how "big" is a big tranny cooler ??? should i run 2 ?? the size of the one i have at the moment is about 300mm x 200mm (rough estimate at the moment). If i run 2, should that be in parallel, or series (one after the other, or side by side)...
I have a big one behind the radiator and it is run in series with a small one which I have mounted on the right hand side of my Group A front spoiler air dam (oppisite to the cold air induction) Makes a big difference and keeps mine cool....
I will have to go down and measure them. I just know from looking at alot of them in my time that big is big and small is small.
I forget the brand of the small one but it has some twist design in the fins which apparently are way more effiecent than the ordinary. My original "Big One" was godd for cruising but when I put the boot into her, especially in sumer, it go pretty hot. Mind you, it is the last to get the air after thr intercooler and radiator 8O
I will go down and measure them and I will post the sizes

Ok....
The biger oe that is behind the radiator is 42x22 3.5cm. Although this is the big one, like I said, the air has to get through the intercooler and radiator before hitting it. This is then in series with the one I was describing before, or how HSVSUX decribes it "BTR cooler". This one is 30x15x2cm (that one is a little rough as I would of had to take the wheel off to get to it).
Now with those two, it sits on 180deg fahrenheit with normal cruising on a hot day. If I am down the track on a hot day, it will raise to about 220 after about 5 runs end on end. All I do then is shut her down, go have a perve and a drink then jump back in and do it all again.
When I only had the single big one. It would cruise on 200-220 and then really heat up when giving it a boot full.
If you want to keep and eye on things, install a trans temp gauge to keep an eye on it. For around $100 it is worth while! There are also additives you can add to the fluid that can help keep the fluids cooler.
Hope this helps

yep.. sure did - thanks for that info vlt06...
i have 1 tranny cooler - about the same size as your small one mounted just behind the bumper (before the radiator, so it gets the cool air first) - i assume this wont do for the 3000 stally ???
might get a temp guage for the transmission when i can to keep an eye on it..
so 180F is ok, 200F is running a bit hot, and 220F is getting up there and time to let it cool down ??
For me about a half an hour of just shut down. Or, if boosting quite a bit on the road. Just returning to normal driving will bring her down as well. Example, last night I went to fill the VL up at Albany creek (I live at Strathpine). At the servo was a Mistubishi GSR turbo thing (huge turbo & intercooler etc...). We both left the servo at the same time and raced all the way towards the city, down Rode Rd towards Nundah, then left up Sandgate Rd all the way to the Redcliffe turn off. Both of us were hammer and tongs every posible chance. By the time I finished mucking around, my box was on about 200deg. Another 15mins of normal driving brought it back to the 180 mark. Now it is not every day you are doing that kind of ****. Well, not me any way....
If you run 'Redline synthetic trans fluid' you can run it to 310F. normal fluid is shagged at 260ish.
My car on the track runs between 220 and 280 all day.
I have 2 big BTR style coolers, cruising on the street it only runs 160 - 180.
Just take a little into account about where you are and outside temperatures. Obviously, Example, places like Melbourne have considerably less temp during the day then we do in Brisbane here. Where they may be running a little cooler, we are always going to be a bit warmer :roll:
Transbrake's put enormous strain on the transmission when "popped". For the people that aren't familiar with their operation, holding the transbrake button down at the light's load's up the engine to the point where your all spooled and ready to lift off. Once the button is released, the car pick's up the wheel and goes, just like dumping the clutch in a manual car. So at the track, you have the best of both world's with the transbrake, but on the street it's a lesson in ice skating!

8O 8O 8O Why would you have a cooler behind the radiator,
I recommend you put it in front of it.

A few reasons, with the AVO II intercooler, there is not much room between the two. Then is the priorty thing, which would I rather over heat first??? engine or box??? I think box. Thirdly, I don't have a problem with heat the way it is now so there is no need to change. Maybe if I didn't have the intercooler though
