tranny cooler questions -UPDATED, ...like...how, what, where??? Options

[naro914]

Hey all,
so it's become obvious to me that I need a transmission cooler set up. With 330 hp and using a 901 box, it's going to start destroying gears (already did this past weekend at Road Atlanta).

So, what is everyone using and how are they set up? What pump & cooler? are you using a resevior/tank? Where is the cooler mounted? and where are you getting the oil in and out of the trans?

As you can see, I'm a complete newbie about this, need to educate and do as quickly as possible...I'm running out of transmissions!

Pictures would be wonderful...

thanks!!

I used the method above and it worked just fine (details below. There are two things about the system that keep the cooling circuit from dumping the fluid back into the trans while stopped. My cooler is mounted vertically so that the inlet and outlet are on top and I have a 2-psi backflow valve at the geared (self-priming) pump.

I added nearly a quart more fluid to fill the entire cooling system.

My sequence:
1. filled the tranaxle like normal (I have a hole in my trunk floor that lets me run a funnel/line into the fill hole) The trunk-hole is then plugged with a rubber stopper.
2. disconnected the inlet line and pointed it at a catch-can on the floor
2. ran the unprimed pump until there was a steady stream of fluid out of the inlet line
3. turned the pump off and made sure the only line dumping into the case after the pump was turned off was the return line from the cooler to the case.
4. reconnected the return line and added (as it turned out) 15.5 oz more fluid.

Total line used was about 14 ft.
Total oil capacity ~3.75 quarts

Most have seen it but pix are on page three in this thread starting at post #50.
