You will not need a tranny cooler with your 3000 stall converter. I had a 3000 in my '00 C5 for three years and the tranny fluid temps on got over 200 degrees twice in all that time. I've since installed a 3500 stall converter and my tranny temps still only average in the 160-180 degree range.
With the C5 tranny in the rear, isolated from engine heat, and better situated for fresh air cooling, auxiliary tranny coolers aren't normally needed.
Why don't you just install it without one and monitor your ATF temps via your DIS for awhile like I did? If they stay in an acceptable range then you know you're ok and if they do for some reason run higher than they should, you can always add a cooler later. I personally don't like the idea of adding one unless it's really necessary as they add that many more connections that could spring a leak. I once had a hose pop off the tranny cooler on my '99 SS while I was doing about 75 mph on the Interstate. Believe me, it wasn't pretty.
